Dr. Kent Wilken

Kent WilkenFaculty Co-Director

Professor Wilken works on compiler optimization, an important method for speeding up computer programs. Until recently finding exact solutions to important compiler optimizations such as instruction scheduling and register allocation was considered intractable. However our research has shown such optimizations can be solved exactly in reasonable time using methods from combinatorial optimization. The research is extremely practical (new techniques are built inside a real compiler) while being theoretically rigorous. The research includes an interesting blend of computer engineering and applied mathematics.


Corey D. Wolin

COREYLab Manager

With a background in both electrical and materials engineering, Corey assists lab members in bridging the gap between the two closely related disciplines. He serves as the lead engineer setting staff priorities to assure all of the user needs are met. He also serves as our industrial correspondent, assisting outside companies and startups with process development to meet their research goals. Due to his background in materials science, Corey has a strong understanding of various thin film deposition techniques at the atomic level, and recently performed extensive characterization on the new RF/DC Lesker sputtering system. This equipment characterization process is key to streamlining research for our users, and helps decrease the amount of trial and error required on their end. Corey also serves as the Laboratory Safety coordinator making user safety a top priority.


Dr. Yusha Bey

BeySenior Development Engineer

Yusha Bey received the B.S. degree in electrical engineering from Morgan State University in 2005 and the Ph.D. degree in Electrical Engineering from Purdue University in 2012. He was a post-doctoral research engineer with the University of California, Davis from 2012 – 2014. As a student, he was selected to participate in several student practicum, such as at the NASA Goddard Space Flight Center (2005) and Lawrence Livermore National Laboratories (2009). Throughout his graduate studies he was a key contributor to several R & D projects for government and industry, including: DARPA ASP, DARPA ART, DOE PRISM, Rockwell Collins, BAE Systems AITR, Northrop Grumman, and Raytheon.
Dr. Bey has extensive hands-on expertise in regards to the theory, design, tape-out, microelectronic fabrication, measurement, and packaging of solid state and microelectromechanical systems (MEMS) devices. In particular, he is an expert on deploying MEMS for reconfigurable radio-frequency (RF)/microwave and sensor applications. Additionally, Dr. Bey has an extensive background in the hands-on instruction of the art and practice of microelectronics fabrication for students and researchers with a wide range of experiences.


Rijuta Ravichandran

rijutaheadshot(square)Associate Development Engineer

With 3 years of extensive experience, Rijuta manages the scanning electron microscope (SEM), focused ion beam (FIB) dual beam system, and materials characterization tools at CNM2. These materials and microanalysis tools include energy-dispersive x-ray spectroscopy (EDXS), and electron backscatter diffraction (EBSD) analysis in combination with FIB/SEM. Her main responsibilities include formulating and trouble-shooting process flows for FIB in-situ TEM lamella sample preparation.  Additionally, she instructs and assists researchers on preparing, imaging, and analyzing a wide range of materials (polymers, semiconductor devices, ceramics, metal composites, etc).
Aside from her microscopy work, she assists lab members and external customers with cleanroom processing and fabrication. Her recent external projects include providing and implementing suggestions for a pressure sensor, and another for creating microfluidic channels. She is heavily involved with daily operations of the lab, tours, training and scheduling concerns. Rijuta received her B.S. in Biomedical Engineering from UC Davis in 2013.
