Jimmy Zhu

Jimmy Zhu received his B.S. in Physics from Huazhong University of Science and Technology in China and his M.S. and Ph.D., also in Physics, from the University of California at San Diego. He was an assistant professor and later associate professor in the Department of Electrical Engineering at the University of Minnesota before joining the Department of Electrical and Computer Engineering of Carnegie Mellon University in 1996. He received an NSF Presidential Young Investigator Award in 1993 and the 1996 R&D100 Award for the CPP/GMR read sensor patent, one out of the twelve U.S. patents he currently holds.

Mostafa Bedewy

Dr. Mostafa Bedewy is an Assistant Professor of Industrial Engineering at the University of Pittsburgh, where he leads the NanoProduct Lab (www.nanoproductlab.org).  Before that, he worked as a Postdoctoral Associate at the Massachusetts Institute of Technology (MIT) in the area of bionanofabrication with Professor Karl Berggren in the Research Lab for Electronics (RLE).  Also, he was previously a Postdoc at the MIT Laboratory for Manufacturing and Productivity (LMP), working with Professor John Hart on in situ characterization of carbon nanotube growth.  In 2013, he completed his PhD at the University of Michigan in Ann Arbor, where he worked with Professor Hart on studying the population dynamics and the collective mechanochemical factors governing the growth and self-organization of filamentary nanostructures.  He holds a Bachelor’s degree (honors) in Mechanical Design and Production Engineering (2006) and a Master’s degree in Mechanical Engineering (2009), both from Cairo University.  Dr. Bedewy recently received the Outstanding Young Manufacturing Engineer Award from the Society of Manufacturing Engineers (SME) in 2018, the Ralph E. Powe Junior Faculty Enhancement Award from the Oak Ridge Associated Universities (ORAU) in 2017, the Robert A. Meyer Award from the American Carbon Society in 2016, the Richard and Eleanor Towner Prize for Distinguished Academic Achievement from the University of Michigan in 2014, and the Silver Award from the Materials Research Society (MRS) in 2013.  His research interests include advanced manufacturing, nanoscale fabrication, metrology and materials characterization, chemical vapor deposition, carbon nanotubes, hierarchical nanostructure self-assembly, and biomolecular engineering.

Zachary W. Ulissi

Zachary W. Ulissi joined Carnegie Mellon University in 2017, after doing his PhD at MIT and post-doc at Stanford. His research at MIT focused on the the applications of systems engineering methods to understanding selective nanoscale carbon nanotube devices and sensors under the supervision of Michael Strano and Richard Braatz. Prof. Ulissi did his postdoctoral work at Stanford with Jens Nørskov where he worked on machine learning techniques to simplify complex catalyst reaction networks, applied to the electrochemical reduction of N2 and CO2 to fuels. The Ulissi group builds on this foundation to model, understand, and design nanoscale interfaces using modern predictive methods to guide detailed molecular simulations.
