TzahiTzahi Cohen-Karni is an Assistant Professor at the Departments of Biomedical Engineering and Materials Science and Engineering in Carnegie Mellon University, Pittsburgh, PA, USA. 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, USA, 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. 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 He was awarded the Charles E. Kaufman Foundation Young Investigator Research Award. In 2016 Dr. Cohen-Karni was awarded the NSF CAREER Award.

Ph.D. Students

SahilSahil Kumar Rastogi (2015-present) graduated from Carnegie Mellon University in 2015 with a M.S. degree in Biomedical Engineering where he studied the influence of particle size and surface modification on the uptake efficiency of nanoparticles in live mammalian cells. He was awarded the Summer Graduate Fellowship at CMU. Prior to joining CMU, he graduated with a B.Tech. degree in Biotechnology from Indian Institute of Technology, Guwahati, India in 2013. There he received the Institute Merit Scholarship for academic excellence. In 2012, he was selected for the Undergraduate Training Program in Temasek Lifesciences Laboratory at National University of Singapore, where he worked on developing a new nano-particulate diagnostic platform for microbial diagnostics. His interests lie in the application of nanotechnology in creating diagnostic and therapeutic platforms.



Anna Kalmykov (2016-present) obtained her Master of Science degree at Boston University in Biomedical Engineering, where she worked on developing flexible electronic substrates to deliver electromechanical stimuli to regenerative cardiac patches. During the course of her graduate career, Anna interned as a catheter engineer supporting new product development and sustaining engineering for spray cryotherapy technology. Prior to her graduate career Anna worked as an associate scientist in upstream research and development laboratory, where she conducted microbial and mammalian recombinant protein expression. Anna holds a Bachelor of Science degree in Biochemistry from the University of Maryland at College Park.


M.S. Students

RaghavRaghav Garg (2015-present) graduated with distinction from Indian Institute of Technology- Kanpur (IIT-K) in 2015 with majors in Biological Sciences and Bioengineering. There he received the Academic Excellence Award for his academic performance. Throughout his undergraduate program Raghav explored cancer biology and cancer mechanism. His undergraduate project focused on defining the causality behind aberrant homeotic gene expressions and carcinogenesis. For his cancer research at IIT-K, he received the Sagnik Ray Scholarship. In the summer of 2014, Raghav conducted research at Purdue University, where he worked on developing novel therapeutics to reverse hypoxia induced methylation modifications in tumours. He received the Summer Innovation Award at IIT-K for his research at Purdue University.
