Dr. Elka Georgieva


Title: Assistant Professor

Education: Ph.D. in Chemistry from Bulgarian Academy of Sciences with Prof. Nicola Yordanov

Postdoctoral Training:

  1. Department of Biochemistry and Biophysics, Stockholm University with Prof. Astrid Gräslund.
  2. Department of Chemistry and Chemical Biology, Cornell University with Prof. Jack Freed.

Research Area: Georgieva's group uses multidisciplinary approaches to learn the structure, conformational dynamics, and function of membrane proteins at the molecular level. Particularly, we are interested to understand the structure and functional mechanisms of:

  1. Viral protein in cellular membranes with emphasis on proteins from oncoviruses.
  2. Membrane exporters from pathogenic bacteria with emphasis on Mycobacterium tuberculosis (Mtb).
  3. Lipid-interacting human proteins linked to cancer.
