Megan (Pomianek) Bolitho graduated summa cum laude from Loyola
College in Maryland in 2004 with an interdisciplinary degree in
chemistry and biology. Her academic interests at the intersection
of these two disciplines led her to join the lab of Prof. Martin
Semmelhack at Princeton University for graduate studies. Here she
pursued research projects focused on quorum sensing, a process
through which bacteria communicate with one another using small
organic molecules called autoinducers.
In the Semmelhack lab, Megan was responsible for designing and
synthesizing small molecules to probe quorum sensing systems. Her
work - together with close collaborators in molecular biology - led
to the identification of a novel autoinducer in the pathogenic
bacterium Vibrio cholerae and the first demonstration that quorum
sensing circuits may be viable targets for a novel type of
anti-microbial agents.1 Megan's graduate research was
recognized and supported by fellowships from the American Chemical
Society's Division of Medicinal Chemistry (2006), the
Horst Witzel Prize from Cephalon Corporation (2007), and prizes
awarded by Wyeth Research (2007) and Elsevier (2008). After
receiving her PhD degree in early 2009, Megan switched from working
on the chemical to the biological side of quorum sensing by joining
the lab of collaborator Bonnie Bassler, where she contributed to an
understanding of the dimerization of a quorum sensing receptor
protein.
At USF, Megan's research interests build on her background
in quorum sensing. Her lab uses the techniques of organic
synthesis, biochemistry, and molecular biology to develop
inhibitors of quorum sensing in bacterial pathogens and means of
evaluating them.
