Research Abstract:

Work in my laboratory combines biochemical and biophysical techniques to shed light on the detailed interactions between macromolecules that are central to the biology of all organisms. In particular we use single-molecule techniques such as optical and magnetic trapping in combination with fluorescent methods to understand molecular mechanisms leading to transcription and its regulation. Current projects in the lab include open complex formation by the Eukaryotic pre-initiation complex and mechanisms of mycobacterial transcription regulation.

Mentorship and Commitment to Diversity Statement:
I believe in supporting all members of my laboratory, the program, the division, and the school. The scientific pursuit, today and tomorrow, depends on thoughtful and active student mentorship. This includes training in the scientific method itself, as well as the more technical aspects of research. I know from experience that different students often benefit from different kinds of support and try to adapt my mentoring style accordingly.

I recognize that systematic racism and sexism has resulted in a lack of diversity in scientific endeavors. Due to the systemic nature of the issue, the active engagement of all those placed in leadership roles within science is needed. Along these lines, I pledge to push the systems in which I participate including my lab, my department, my graduate program, and my university towards a more just and representative distribution of our broader community.
