Research Interests

I am applying a variety of evolutionary, bioinformatic, and molecular techniques to address two facets of long non-coding RNA biology: 1) I want to know how lncRNA function impacts conservation at the sequence, structural, and transcriptomic level, and 2) I would like to use evolutionary and transcriptomic analyses to identify strong candidates for functional analysis, particular stress-responsive lncRNAs.
