Welcome to the:

We are a group of RNA enthusiasts working on unsolved scientific mysteries related to human health and disease. Our group is particularly interested in the biochemistry of different RNases and the effects of their activation in human cells.

Welcome Anakha!

We are excited to welcome Anakha Shah as our OSU SURE summer intern. Looking forward to a great summer of research!

April 2026

Welcome Daniel, Gabby & Sydney!

February 2026

New Publication in RNA!

Our latest work “Stalled translation on transcripts cleaved by RNase L” is now out in the journal RNA.

November 2025

CRB Seed Grant Awarded

The lab has received new funding for a collaborative project with the van Hoof lab to explore the connection between ISR and tRNA introns.

Research Areas

RNases can cause the Ribotoxic Stress Response (RSR)

PolyA tail remodeling during the innate immune response

How do RNA modifications influence the innate immune response?

Collaboration with the van Hoof lab

How do lack of tRNA introns cause the Integrated Stress Response?
