Tzahi Cohen-Karni is an Assistant Professor at the Departments of Biomedical Engineering and Materials Science and Engineering in Carnegie Mellon University. 

Dr. Cohen-Karni received the Gold Graduate Student Award from the Materials Research Society in 2009, and received the 2012 International Union of Pure and Applied Chemistry Young Chemist Award. In 2014, Dr. Cohen-Karni was awarded the Charles E. Kaufman Foundation of the Pittsburgh Foundation New Investigator Research Grant, and in 2016, he won the NSF CAREER Award. Additionally, in 2017, he won both the Cellular and Molecular Bioengineering Rising Star Award and the Office of Naval Research Young Investigator Award.

Dr. Cohen-Karni is a member of the American Chemical Society, the Materials Research Society, and the Biomedical Engineering Society.


He received both his B.Sc. degree in Materials Engineering and the B.A. degree in Chemistry from the Technion Israel Institute of Technology, Haifa, Israel, in 2004. He obtained his M.Sc. degree in Chemistry from Weizmann Institute of Science, Rehovot, Israel, in 2006 and his Ph.D. in Applied Physics from the School of Engineering and Applied Sciences, Harvard University, Cambridge MA, in 2011. He was a Juvenile Diabetes Research Foundation (JDRF) Postdoctoral Fellow at the Massachusetts Institute of Technology and Boston Children’s Hospital at the labs of Robert Langer and Daniel S. Kohane from 2011 to 2013.


Tzahi Cohen-Karni’s research has focused on the unique interfaces between biology and nanoscience and nanotechnology, by applying techniques from chemistry, physics, and materials science to explore the rich world of biology. His interests cover a broad area from the interactions of biomolecules, cells, and tissues with nanostructures (such as nanowires, nanotubes, and nanoparticles), to the electrical properties of tissues and cells interfaced with nanodevices.
