Charishma Cohen, Ph.D.

Associate
Electrical Engineering & Computer Science

Dr. Cohen is formally trained in electrical engineering with a focus in device fabrication, solid-state physics and nanotechnology. She has experience in failure analysis of battery systems, of consumer electronics at the system, board and component level.

Prior to joining Exponent, she worked as a Research Assistant in the Bioelectronic Systems Lab at Columbia University in the department of Electrical Engineering, focusing on building a novel method to desalinate water using carbon nanotubes. The project involved a mix of electrochemistry, physics and electronics to design a single nanotube device to study ionic pump effects through the interior of sub 1nm carbon nanotubes. Through this work, she has gained experience in device fabrication and custom experimental testing of concepts. Before graduate school, she worked on separation of metallic and semiconducting carbon nanotubes that resulted in an issued US Patent on which she was a named inventor. Additionally, she has experience with characterization techniques including scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy.
