Greta Babakhanova, Ph.D. (Fed)



Greta Babakhanova is a Physicist in the Biomaterials Group. Previously she was a NIST-NRC Postdoctoral Research Fellow working with her advisor, Dr. Carl G. Simon Jr. Her current objective is to develop robust standard protocols for measuring cell viability in three-dimensional scaffolds.

She completed her PhD in Chemical Physics from the Advanced Materials and Liquid Crystal Institute, Kent State University in 2019. Her dissertation research was performed in the lab of Dr. Oleg D. Lavrentovich where Greta worked on characterizing twist-bend nematic liquid crystals using electro- and magneto-optical methods as well as electron microscopy techniques. She also developed stimuli-responsive elastomer coatings with pre-determined surface topographies.
