Assistant Professor of Computer ScienceAdjunct Assistant Professor of Biological Sciences
I am inspired by proteins. I would like to understand how each protein's function is encoded in its molecular structure and amino-acid sequence. This is a highly interdisciplinary pursuit, involving concepts from biology, physics, mathematics, computer science, and chemistry. Understanding the language of proteins will lead to cures for human diseases and will teach us how to engineer smart novel materials.
