Ascaris infects 1.5 billion people a year (#1 geohelminth)
Ascaris epidemiology: more parasites less allergic disease
Can Ascaris products induce regulation of inflammation?
Can we exploit the Ascaris regulatory components and develop
therapeutics to prevent allergic inflammation?

Naval Biomedical Reasearch Funding is all
soft money GRANT WRITING!!!
Know how to write a good grant
Most grant submissions will not be fundedlearn from your mistakes and resubmit
Funding cont.
• NIH funding lines- 7-10%
• DTRA funding lines- 4%
• Funding is becoming more
difficult and requires
tenacity
• Think outside the box for
potential funders
