Overview: I am a graduate student in University of Virginia School of Medicine Biomedical Sciences program. My Ph.D. track is in Biophysics. Broadly I am interested in applying cryo-electron microscopy to determine structures to high resolution and biophysical assays to understand biological systems.
Background: In previous research I used solution NMR along with circular dichroism, fluorecence anisotropy and mass spectrometry to look at structural components of the Type 3 Secretion System from bacteria such as B. pseudomallei. I also have experience in tissue cell culture working with the obligate intracellular pathogen C. trachomatis. Here I helped design a new tool to allow us to study Chlamydia with more ease.
Where do I see myself in 5 years? Hopefully done with my Ph.D. and heading to do a post-doc abroad.
