Research

I am interested in developing and using genetic engineering tools and systems biology to understand how environmental stimuli affect cellular processes. My current research focuses on using advanced genetic engineering tools such as CRISPR/Cas to build sense-and-respond systems that will detect viral infection in live cells.
