I have a passion for science, and believe it represents an important path to truth. As a physicist, I search for fundamental explanations for our experience. For me, understanding how life can arise from the physical interactions of matter and energy is the greatest mystery. In my research, I apply quantitative methods to complex biological problems.

What I Love About Emmanuel:

I love that Emmanuel is a community. It is a place where students and faculty can know each other and work together in a way that would not be possible at larger institutions.

I use quantitative science to understand the molecular basis of life. My students and I have developed methods to observe interactions between individual molecules of DNA and proteins. Our data has helped us understand how DNA binding proteins search the genome for their specific binding sites. This work has contributed to our fundamental understanding of genetic regulation in cells as well as to evolving biotechnology such as gene editing. We are also developing and applying methods in data science, such as computer vision and numerical simulations, to complex biomolecular processes.
