Research Areas and PhD Mentors
The heart of graduate education is research. The relatively small size of research groups in our department promotes enhanced interactions between the faculty mentors and the students, ensuring a first-rate education in impactful research areas. The Department of Chemistry at Georgetown University is equipped with state-of-the-art instrumentation to facilitate the wide array of research carried out by students, faculty, and staff. The current areas of research are listed below with faculty contact information and links to the faculty websites.
Esther Braselmann, Clare Boothe Luce Assistant Professor, firstname.lastname@example.org
Research Interests: Our group investigates RNA molecules in living cells. RNA localization within each cell is closely linked with proper cell function. Disease states disrupt RNA dynamics, including infection with intracellular pathogens. We use spectroscopic and biophysical techniques to develop RNA labeling strategies and fluorescence microscopy to label and track RNAs live.
Keywords: Fluorescence microscopy (widefield, confocal, lifetime), major biochemical techniques (cloning, protein characterization), fluorescence spectroscopy, bacterial and mammalian cell culture.
