Lab: Barrios

Background:

For my predoctoral work I studied under Dr. Cynthia Burrows and made several novel protein mutants to build a unique molecular device which was able to sense RNA modifications and non-conventional DNA folds which required a combination of biochemical and analytical chemistry knowledge. This work is finished, though unpublished due to a combination of the coronavirus pandemic and health issues but is forthcoming.  Thus far in my post-doctoral training under the mentorship of Dr. Amy Barrios I have used a previously described fluorescent tool to record enzyme activity in live cells.

Research interests:

Peptides, Molecular tools, Drug discovery, DNA/RNA
