Marie E. Egan, M.D., associate professor of pediatrics and of cellular and molecular physiology, has won the Hartwell Individual Biomedical Research Award for her research on the use of nanoparticles to treat cystic fibrosis (CF). The award, given to twelve scientists per year, includes a grant of $100,000 per year for three years. The technique Egan is investigating involves replacing short fragments of DNA in the gene responsible for CF, to correct a known mutation in the common genetic disease. CF affects the entire body and can cause early death.
