Curriculum Vitae
Blaha Research Group


Dr. Blaha obtained his Ph.D. from the Vienna University of Technology, Vienna, Austria in 2001. His doctoral work focused on investigation of the translational apparatus using structural and functional approaches. In his post-doctoral research, Dr. Blaha continued his structural research on protein translation under the guidance of Nobel Laureate Thomas Steitz. In 2012, he joined the Department of Biochemistry at UC Riverside as Assistant Professor. Since then, his research has focused on the interplay between protein translation and transcription.

Research Interests

In prokaryotes, transcription and translation are coupled. In vivo, decoupling transcription from translation leads to stalling of transcription on a genome-wide scale. This stalling causes DNA double strand breaks and therefore genome instability. Recent advances indicate that the interplay between RNA polymerase and the ribosome is at the core of this coupling. The basis of this interplay remains elusive. We are currently investigating the direct interactions between RNA polymerase and ribosomes, identifying both the interface between them and the thermodynamic and kinetic parameters for their interactions.
