Irina
Catrina

Clinical Assistant Professor of Chemistry

Ph.D. Utah State University, UT - Biophysical-Organic Chemistry
B. Eng. University "Politehnica" of Bucharest, Romania- Macromolecular Compounds

 

Irina Catrina received a Physical-Organic Chemistry Ph.D. degree from Utah State University, UT, and a Chemical Engineering degree from the "Politehnica" University of Bucharest, Romania. At USU, in Alvan Hengge's laboratory, she studied the use of phosphorothioates as models for deciphering the mechanism and transition state structure of phosphoryl transfer reactions. She then studied nucleic acid folding and developed a microarray to improve prediction of RNA secondary structure in Douglas Turner's laboratory at the University of Rochester, NY. From Rochester, she moved to Worcester, MA, where she studied viral RNA replication in Maria Zapp's laboratory at the University of Massachusetts Medical School. In Diana Bratu's lab at Hunter College of CUNY, NY she used RNA visualization techniques to study endogenous and viral RNA trafficking in live fruit fly egg chambers. Her current research focuses on the development of in vitro assays to facilitate fast and easy design of efficient probes that allow the study of RNA-RNA and RNA-protein interactions that are essential for organism development.
