Lab Members

Open Positions

We are interested in hiring motivated and highly talented post-doctoral and post-baccalaureate fellows, particularly those with expertise in protein or nucleic acid biochemistry, mammalian cell culture, genomics and other high-throughput methods, or single-molecule microscopy.

Consistent with the NIH Unite Initiative, we strongly value diversity in hiring and strive for a welcoming and inclusive culture in the workplace.

Our Fellows

Agnes Karasik.
Agnes Karasik, Ph.D.
Postdoctoral Fellow IRTA

B.Sc. – ELTE, Hungary
M.Sc. – ELTE, Hungary
Ph.D. – Uniformed Services University of Health Sciences

Agnes studied RNase P for her PhD research and is now exploring the non-canonical role of virus activated ribonuclease L in protein translation.

Kelsey Bettridge.
Kelsey Bettridge, Ph.D.
Special Volunteer

B.A. - Lawrence University
Ph.D. - Johns Hopkins University

During her PhD studies, Kelsey used single molecule tracking to understand how RNA polymerase finds promoter sequences in bacteria. Kelsey is currently studying the dynamics of translational readthrough and reinitiation in live human cells using advanced imaging techniques.

Kyra Kerkhofs.
Kyra Kerkhofs, Ph.D.
Postdoctoral Visiting Fellow
B.S. - University of Antwerp, Belgium
M.S. - University of Antwerp, Belgium
Ph.D. - York University, Canada
As part of her PhD dissertation,Kyrastudied processing of non-coding RNAs inTetrahymena thermophila. Her current project focusses on understanding the molecular mechanism of ribosome recycling during viral infection.
Sarah Miller, Ph.D.
Postdoctoral Fellow IRTA
B.S. - Texas Tech University
Ph.D. - Texas Tech University
During her PhD studies, Sarah studied the mechanism of how mRNAs encoding secretory proteins are degraded. She is now investigating the role of quality control pathways and translation in metabolic disease.
Corey Knowles, Ph.D.
Postdoctoral Fellow IRTA
B.A. - University at Buffalo, SUNY
Ph.D. - University at Buffalo, SUNY
For his graduate studies, Corey studied mechanisms of host responsive translational regulation in the pathogenic fungus, Cryptococcus neoformans. He is now studying how stress and amino acid sequence can change gene expression at the translational level.
