GREETINGS, SACKLER A letter from your Sackler Student Council By Har i Rallapalli Dear Sackler Community, Congratulations and welcome to the incoming class of 2015! We are very excited to have you join our community here at NYU School of Medicine. Orientation is a crazy time filled with learning the nuts and bolts of graduate school. We, the Sackler Student Council (SSC), are all second year PhD students, so we were in your shoes exactly a year ago and would love to share all that we?ve learned since our own Orientation. If you need advice on picking rotations, classes, or what to do on the weekends, we can help. And that help isn?t just limited to SSC members ? Sackler is a community where everyone is excited to have you and willing to give you help and advice. So don?t hesitate to speak to any of us! Looking forward, there are a few things that we as the SSC want to accomplish throughout this year. First, we are introducing a new role: a representative liaison for each year. Class liaisons will ensure that people at every stage of graduate school have a voice in the SSC. We want students in every year to feel that they are being heard and their needs are being met. We will also send a brief monthly newsletter directly to the student body to keep everyone up to date on SSC happenings. Both of these new initiatives will increase transparency and open communication be- tween the student body, the administration, and SSC. Our priority as SSC is to make the Sackler experience as wonderful as possible for every student. To that end, we will continue the role of Diversity Chair on the SSC. This will allow for a stronger focus on the issues affecting students of color and will better facilitate inclusion of our whole community. Hari Rallapalli Joshi Frenster Cassidy Reich Patty Martin Phillip Thomas Ilona Kats Lastly, we want to focus on building stronger relationships with industry to provide more opportunities for students to explore alternative careers to academia. We are all thrilled to be on SSC this year and to have the opportunity to contribute to the Sackler legacy. Don?t hesitate to contact us with any questions or concerns. Sincerely, Har i Rallapalli, President Joshi Frenster , Vice-President Cassidy Reich, Treasurer Patty M ar tin, Secretary Phillip Thomas, Diversity Chair I lona K ats, Social Chair ?

Melissa Zuroff, Student Advisor (212) 998-4249 [email protected] A LOOK BACK ON FIRST YEAR Thoughts from students who thrived during their first year at Sackler By Russell L edet These second-year students look back on their first year ? ups, downs, victories, and challenges. In this piece, they offer advice to new students just getting started on their journey through graduate school. I interviewed: Er ica Br iggs is in the Molecular Pharmacology program and has joined Dr. Susan Logan?s lab. Phillip Thomas also joined the lab of Dr. Susan Logan in the Department of Microbiology. Steven Hoang-Phou is a new member of Dr. Markus Schober?s lab in the Molecular Oncology and Tumor Immunology Program. W HAT ARE YOUR THOUGHTS REGARDING YOUR FIRST YEAR? E: First year was very exciting, but also filled with challenges. Each lab rotation introduces you to new research and lab techniques. Starting from scratch every few months is challenging, but in the end you learn a lot and feel accomplished. P: Wow, I can?t believe I made it! Graduate school has been one of the toughest academic experiences in my life, and there were many times during my first year where I was sure I wouldn?t make it. In hindsight I was wrong, but I needed that humbling experience. Not only did I grow from it, but I worked that much harder to ensure my success. S: This was definitely one of the most challenging but rewarding experiences of my life! I have never felt as pushed and motivated to learn as I have in the past year. Almost everything you learn will be applicable in some way, shape, or form during your time here. Also. Sleep, fun, and success ? sacrifice one. DO YOU HAVE ANY ADVICE ON SUCCEEDING IN FOUNDATIONS, THE FIRST COURSE FOR NEW STUDENTS? E: Be patient! Foundations differs from most undergraduate courses in that the format is more discussion-based: on lectures from PIs as well as scientific papers. Give yourself time to adjust and take your time to thoroughly examine the readings. Also, recording the lectures is very helpful when reviewing for exams. P: From Dr. Angus Wilson?s speech on the first day stating, ?Graduate school is a lifestyle? to first-test jitters, Foundations is the course that will break you into the grad school experience. My advice is to fight the notion that classes don?t matter in graduate school and take it seriously. You receive instruction by brilliant professors, and the more you put into the course, the more you?ll get out of it. S: Read! You'll need to read and research extensively to gain relevant background information for each topic. Reading and making connections between the literature, current THE SACKLER MESSENGER 5 findings, and overarching themes will definitely help when it comes to test time or (more importantly) your research, when you need to find ways of answering your own questions.? ? HOW DID YOU MANAGE THE TURBULENT TRANSITION TO GRAD SCHOOL IN THE BIG APPLE? E: Don?t be afraid to explore, but don?t go to Time Square! I really love wandering through the East Village (closer to the NYU main campus) and Chelsea (the High Line is great at sunset). You?ll find areas you like, just try new neighborhoods with your classmates each weekend. For transportation, NYC Subway apps are a must for all subway rides (it downloads the entire subway map to your smartphone)! Google Maps is always helpful for mapping trips, too. P: Moving to New York was a major adjustment for me, and I think there?s little you can do to prevent that. However, one of the ways that I eased the transition was to develop a network of friends. Being around a group of supportive people with whom you can unwind makes it harder to miss home. It?s also much easier to explore and do new things when you?re with a group rather than by yourself. Or, if you're in a rush, pro-tip: Halal carts are amazing. W HAT QUESTIONS SHOULD FIRST-YEARS ASK W HEN SELECTING ROTATION LABS? E: Try to figure out how well you communicate with your PI. Feel free to ask him/her about their management style. You should also speak with other graduate students in their lab. This will give you a good idea of the lab dynamics (from the PI and the student perspectives) before the rotation. P: The one thing that I would suggest to ask a PI during the rotation period is their mentoring style. You want them to expand on this answer, and you want to evaluate the things they speak on. You want to ensure that the things they mention are compatible with the things that you need as a student to be successful. As students we are often intimidated by PI?s, and will often be so caught up in the idea of making a good impression that we wont ask the tough questions that are most important to us. We have to fight that fear, and ensure that this relationship contains the aspects of it that we as students need to be successful. S: Make friends and explore everywhere (but don't get carried away)! Time management will be very important. Food is expensive and the portions are smaller here. Learn to cook. S: Always ask about the research going on in the lab - chances are you'll be working on a part of an existing project. It also doesn't hurt to know whether or not the PI will actually be accepting any students and what their avail- Erica Briggs Phillip Thomas 6 THE SACKLER INSTITUTE ability is like (are they always travelling, etc). Make an effort to also talk to the other grad student lab members before/during your rotations about their experiences also since you may very well be in their shoes soon. HOW DID YOU MASTER TIME MANAGEMENT W HILE JUGGLING LAB AND COURSEW ORK? E: PIs usually understand your coursework demands, so keep an open line of communication. If you need additional study time, tell your PI and work out a schedule to accommodate both coursework and research. When studying is light, you can dedicate more time to your lab work and make up for any lost ground. P: One of the things that I found most valuable in managing lab work along with my course work was creating a routine. I had set days/times where I would focus mainly on the work I had for courses and other times for lab. Lab is often unpredictable, but I put in a massive amount of work to ensure that nothing would throw off my routine. S: Speaking of time management, things are always guaranteed to take longer than you'll think so plan ahead and get things done early! There is usually plenty of downtime in the lab during incubations. Make the most of it ? you can use that time to catch up on reading for classes. ? Steven Hoang-Phou FROM WAYWARD TO WISE Tips on securing the right graduate mentor for you By Lydia Gr mai Scene: You?re in lab at 10 PM on a Sunday night, woefully finishing a Western blot to repeat an experiment for the third time in a week. You?re dreading your 8 AM Monday morning meeting (because your boss has to know every result immediately and has back-to-back meetings all day). You?re wondering why your PI couldn?t just wait another day for the result. And the worst part: this isn?t an anomalous weekend for you. Each week, Dr. PI wants to see the outcome of every single experiment, and fewer than two productive weekly meetings is an obvious sign of laziness. You drag yourself through 12-hour day after 12-hour day in lab, wondering why you can?t just analyze your data over the weekend instead of making a figure that your PI expects in his/her inbox by Friday night?s end. Sounds miserable, right? This is (I hope) a gross exaggeration of a ?micro-managing? PI. But save for hyperbolic atrocities, such a PI is not uncommon in academia. And such a lab environment may, in fact, sound truly awful to you. The grad student depicted above is probably chatting with first years during orientation, warning them to steer clear of this lab at all costs. But is this really the correct advice to give to newly minted grad students? As Dr. Indira Raman from Northwestern University puts it, ?one person?s neglect can be another person?s freedom [and] one person?s micromanagement can be another?s nurturing.? Dr. Ben Barres, a neurobiologist at Stanford University School of Medicine, underscores the importance of choosing the right thesis advisor for ensuring a graduate student?s long-term success. This is to say that the chances of a grad student ?making it? aren?t a direct reflection of rote intelligence or scientific capabilities (we are all brilliant and capable, that?s why we are here), but rather of proper guidance through the academic journey. In his article (published in Neuron in 2013), he suggests a two-part screening process for first-year grad students looking to select a thesis advisor. So what are these two parts? According to Dr. Barres, the only two things that should be sought in a thesis advisor are: 1) a good scientist, and 2) a good mentor. Notice that he didn?t say ?sought in a thesis lab.? Dr. Barres cautions against putting too much emphasis on the research topic when selecting a lab. To echo advice given to me as a first-year student that resonated with this article: ?Find a good mentor. You?re a scientist ? you?ll fall in love with the science.? An interesting field is critical, yes ? but science is all about solving puzzles. And the thrill of solving those puzzles is the root from which our love for science often stems. The "One person'sneglect can be another person'sfreedom [and] one person's micromanagement can be another'snurturing." Flickr / Calsidyrose more important thing, he says, is to find a professor who is a good scientist that can and will turn you into one as well. To visit an excerpt from the article: ?So how can you, a mere first year graduate student, possibly decide which advisors are good scientists? After all, the whole point of earning a PhD is to learn the difference between good and bad science and you haven?t learned how to do that yet!? Excellent point, Dr. Barres ? but wait, he?s not finished? ?The hallmark of a good scientist is generally that he or she asks important questions and makes mechanistic or conceptual steps forward in answering them.? What questions, you ask? Well, the scientist he refers to, my friend, is you! And according to Barres, you should be inquiring about the PI?s rate of publication (a quick PubMed search should do the trick) and whether or not THE SACKLER MESSENGER 7 their work sounds interesting to you. Other factors of varying relevance included their level of grant support, H-index (a measure of citation frequency), and CV. And of course, it goes without saying that advice from senior faculty, deans, and graduate advisors is invaluable. We grad students think we have it all figured out, but if we aren?t careful, that stubbornness can come back to haunt us. Be proactive in seeking such advice, and be open to receiving it. The second part of this process, as Dr. Barres lays out, is ensuring you are selecting a good mentor. You want a mentor who will design experiments with you, discuss science with you frequently, give you advice and/or experience in grant writing, peer review, and presentation skills. Some of this will be difficult to extract from a cursory meeting with the PI, and so this is where that ?advice? thing comes in handy. Talk to current members of the lab and/or postdocs and faculty who can comment on the PI?s mentoring style. See how happy his/her grad students are as a general gauge of how well you?ll fare if you decide to join. Look at that PI?s track record of mentoring success (pro tip: most lab websites have a list of ?former members? to aid in this search). Ideally, some of their former trainees have gone on to a career in science (whether academia or industry). You?ll be working for this person for at least four years, and you want to be sure this person is equipped to lead you to a successful scientific career. article and see for yourself), I hope what you?ve read here sheds a little light on the advisor selection process. If you can take a few things away from this article, I ask that you choose from these: look for a PI who loves and excels at their science, value a PI who will invest in your long-term success, and heed advice from older grad students, postdocs, and (most importantly) faculty. They?ve been in the game longer than us, and if they are taking the time to offer advice, it?s certainly worth listening to. And lastly, don?t be surprised if you find yourself in lab late on a Sunday night anyway. Don?t always blame it on your boss ? you?re a scientist. You?ll fall in love with the science! ? While this synopsis will do little justice to the mounds of useful advice Dr. Barres supplies in his article (I urge you to read the entire ALUMNI REFLECTIONS Thoughts from past graduates of the Sackler Institute By Paul Chang and M edeva Ghee Paul Chang, PhD Sackler Class of 2006 Neuroscience & Physiology Vice President, Medical Director Cline Davis and Mann yourself and you?ll find that self-awareness will allow you to grow, not just as a scientist, but also as a person. The answers to these difficult questions will help you crystalize your goals and set you on the career path that?s right for you. [email protected] Welcome to Sackler!

From academia, to industry, to strategic consulting, to law, to medical education, to promotional advertising, everyone is looking to employ our most talented. During your scientific training, you may realize a few of these ?alternate? scientific careers appeal to you. But even if you?ve already decided your goal is to start your own laboratory, here are some tips to help prepare you for success, regardless of what that may look like in your future: Explore Your Self. Utilize this opportunity to learn more about yourself. What do you enjoy doing? What are your strengths? How can you improve your weaknesses? Be honest with 8 THE SACKLER INSTITUTE Think Bigger. Are you choosing your discipline or laboratory based purely on personal interests? Will your short-term decisions set you up for long-term success? Will they lead to better publications or collaborations? Which topics resonate beyond academia? Can your research translate into medical and real-world opportunities? Your answers should drive your key decisions just as much as other criteria. Pr ior itize Tr ansfer able Skills. Academia will push you to develop deep scientific expertise on your research topic, but you should really focus on improving the skills that got you there Data mining. Problem solving. Hypothesis validation. Crisis management. Collaborations. Complex idea distillation. Customized communication to different audiences. These skills will help you stand out and will always stay relevant, even when landscapes shift. Expand Your Wor ld. Identify unique ways to translate your experience to non-scientific audiences. Mentor high school or college students. Intern at a pharmaceutical company. Freelance as a medical writer in medical communications. Join consulting groups or other clubs. Volunteer in a clinical setting. You?ll not only expand your existing network, you?ll also improve communication abilities that are highly valued by all future employers. Be Br ave. Exper iment Beyond Your Exper iments. Be humble and embrace the unknown. Try to challenge yourself to explore new areas. There?s never a better time to step out of your comfort zone. It will be harder to do as your career matures. If it?s worth the calculated risk, dive in. The greatest rewards require risk taking. Few will openly admit that the world can be intimidating, full of change and uncertainty. These 5 practices have been critical to my professional growth and I?m so happy I have the opportunity to share them with you.

M edeva Ghee, PhD Sackler Class of 1997 Microbiology Executive Director, The Leadership Alliance Assistant Professor of the Practice of Behavioral and Social Sciences, Brown University Despite the number of years that have passed since my first day at NYU School of Medicine as a microbiology PhD candidate, I still have vivid recollections of my graduate school journey. I?d like to share with you what I have learned as a result of my experience in graduate school as well as an administrator who helps students navigate their academic and career pathways. Star t wor king on an I ndividual Development Plan (I DP). The IDP is a tool that is used to help identify your academic and career goals and the strategies for achieving them. This is an organic and interactive process that should be done in discussions with your faculty mentor. This plan will help you shape your short and long-term goals. Attend financial liter acy classes where possible. It?s so easy to get into to debt or deeper into debt living in NYC. Financial literacy is critical to effectively managing and budgeting limited finances. Find at least one thing that you do outside of your research environment and stick to it! I enjoy cycling. Each year, I watch the Tour de France. As a graduate student, I organized my time to get some time on my bike. Numerous studies cite the benefits of regular physical activity. If you?re not sport-centric then find something you enjoy with a more creative slant. Apply for exter nal funding. Even if you are fully supported by your doctoral program, it is important to apply for external funding to support your graduate training. Writing grants is a critical skill to have as a researcher so you might as well start developing it. Consider NIH Ford Foundation pre-doctoral fellowships. In addition, obtaining travel awards for conferences is also a great way to practice grant writing. Paul Chang I dentify mentor s and a suppor tive networ k in and outside of your depar tment.

Medeva Ghee THE SACKLER MESSENGER 9 Graduate student Diana Klompstra (left, here on Splash Mountain) recently published in Nature Cell Biology about her work on PAC-1, a symmetry-breaking protein that localizes to sites of cell contacts in the developing C. elegansembryo (right, PAC-1 in red). RESEARCH AT WORK Work by graduate student Diana Klompstra sheds light on how embryos begin to differentiate the inside from the outside early in development By Evelyn L itwinoff and Anj elique Schulfer A human adult comprises about 100,000 billion cells. It is amazing to think that a human is more than just a puddle of all these cells; we have tissues and organs with highly specialized structures and functions. How does it happen? It all starts with one cell. If one cell continuously divided in half, specializations would never occur. In order to establish the different progenitors that give rise to our tissues and organs, cells must become polarized. With polarity, cells can divide asymmetrically and begin the process of developing into a complex organism. PAC-1 is a regulator of cell asymmetry and is a crucial protein for cell polarization. Studying the roundworm Caenorhabditis elegans, Dr. Jeremy Nance?s lab in the Skirball Institute identified PAC-1 several years ago and has been working on characterizing its function ever since. PAC-1 is recruited to cell contact sites and promotes asymmetry, but it was unknown how these contact sites were able to recruit PAC-1 and polarize cells. 10 THE SACKLER INSTITUTE E-cadherin, an adhesion protein, is necessary for polarization in many cell types. It is difficult to study the role of E-cadherin in cell polarization due to the fact that it is required in most model organisms for cellular adhesion, which is essential for development to ensue. One lingering question in the field is whether E-cadherin acts as a recruiter to facilitate polarization or if it merely allows proper adhesion so that other contact signals can initiate polarization. Developmental Genetics graduate student Diana Klompstra addressed this question in an exciting new paper published in Nature Cell Biology. By using worms, Diana and colleagues get around the challenges usually associated with E-cadherin studies in other model systems. In the C. elegans model, the E-cadherin homologue, HMR-1, is not required for adhesion during polarization. With this model they show HMR-1 recruits PAC-1 to contact sites for polarization initiation. Additionally, they identified the intermediate binding partners that link HMR-1 to PAC-1. Adding to the complexity of their model, they also found evidence for an E-cadherin independent pathway to recruit PAC-1 to cell contacts, which relies on the PH domain of PAC-1. When asked what she found most interesting about this work, Diana replied, "It was a pleasant surprise to see that mislocalizing Ecadherin was enough to recruit the polarity regulator PAC-1 and depolarize the worm embryo. E-cadherin?s role in polarization has been debated for years and we showed the first clear evidence that it can act instructively in this critical process." Fresh off of this high-profile publication, Diana will be graduating soon and heading to Rockefeller University for a postdoctoral fellowship in the lab of Dr. Shai Shaham. ?
