Research Interests

Computational Genomics, RNA Structure


My group develops computational methods for analysis of new and emerging genome-wide sequencing-based assays that measure structure and abundance of RNA transcripts. We also develop methods to integrate these experimental data into structure prediction algorithms to improve their accuracy and to better predict RNA-protein interactions.
