PRESENT RESEARCH INTERESTS
Development of Drosophila as a model for reproductive toxicity
Understanding the link between Diabetes and xenobiotics
SUMMARY OF RESEARCH
Development of Drosophila as a model for reproductive toxicity
Reproduction is fundamental to life and hence rapid decline in male fertility around the globe
is of serious concern. Several studies attributed this decline to the exposure to environmental

chemicals. In this era of industrialization, evaluation of umpteen numbers of chemicals for
their potential to disrupt male reproduction is a challenging mission and accordingly requires
quick and sensitive evaluation strategies. To date, mammalian models have been on the
forefront of reproductive toxicity assessment for their extrapolation to humans; however,
several issues limit their utility for high-throughput screening. It is pertinent to note that other
in vivo models, apart from these, are relatively scarce. In this context, Drosophila with its
well characterized male reproductive biology has the potential to facilitate quick reproductive
toxicity screening, but this model remains underutilized. To address this issue, in the present
study, we attempted to develop Drosophila based end points for reproductive toxicity
assessment. Development of this system will help to provide a new, rapid, and economical
Drosophila bioassay useful in the preliminary screening of chemicals for their potential to
induce reproductive toxicity.
Understanding the link between Diabetes and xenobiotics
Diabetes is one of the prominent metabolic disorders in India. Approximately, 20% of the
world diabetic cases are reported from India. Several studies have looked into the etiology
and therapeutics of diabetes. However, the link between diabetes and xenobiotics remains
neglected. In this age of industrialization and indiscriminate use of chemicals/pesticides,
understanding the effects of xenobiotics on diabetes/diabetic individuals is essential.
Therefore, we are employing transgenic Drosophila to provide insights to the effects of
environmental chemicals under diabetic conditions and also help to understand the
consequences of chemical exposure in a diabetic scenario with potential implications for the
management of diabetes.
Teaching statement/interests
A teacher has the greatest and sensitive responsibility of shaping up students who in turn
determine the future of a nation/world. In my perspective, a teacher is a facilitator, moderator
and a guide. Biology is something that we are all exposed to everyday and acquainting the
student with the same is what makes me excited about teaching. During my Ph. D., I was
involved in lab courses for the masters’ students in zoology/genetics and demonstrated
cytogenetic techniques or polyacrylamide gel electrophoresis for protein analysis to a class of
30 students. I also mentored two undergraduates in summer research programs and four
students conducting Masters’ dissertation research on topics ranging from basic behavioral
biology in Drosophila to identifying enzymes in the serum that are used as markers for
particular human diseases. As a senior Ph. D. student, I had the opportunity to assist in
supervising four Ph. D. students whose topics included mating behavior, raciation, sexual
selection and role of seminal proteins in reproduction. As a Postdoc and Research Associate
at Cornell University, I mentored three undergraduates in molecular biology techniques
including southern blotting, establishment of and working with transgenic flies. These
experiences made me realize the importance of a “tutoring kind of environment”, where a
teacher and student can discuss the topic and try to relate it to students’ interests. I feel that
working with these students has helped me to improve my skills in explaining biology in
more general and most concise ways. Given my educational and research backgrounds, I
would like to take up teaching in General biology, Cell biology and Genetics,
Biochemistry, Reproductive biology, Toxicology, Developmental biology, Molecular
Biology, Genetic engineering, Transgenics and Evolution.
