microelectromechanical systems research
Karl F. Böhringer 
Karl Böhringer received his Diplom-Informatiker degree from the University of Karlsruhe,
Germany, in 1990 and both his master's and Ph.D. degrees in computer science from Cornell University, Ithaca, NY
(1993 and 1997 respectively). He was a visiting scholar at Stanford University (1994-1995) and a postdoctoral
researcher at the University of California, Berkeley (1996-1998). He joined the University of Washington in Seattle
in 1998, where he is Professor of Electrical Engineering and Bioengineering and Director of the Washington
Nanofabrication Facility and the National Nanotechnology Infrastructure Network site. Böhringer has held visiting
faculty positions at the Universities of Tohoku, Tokyo, Kyoto (Japan), São Paulo (Brazil) and École Polytechnique
F&eagud&eegurale de Lausanne (Switzerland). His research interests include microelectromechanical systems (MEMS),
manipulation and assembly from macro to nano scales, microfluidic systems for the life sciences and microrobotics.
Hal Holmes
Hal Holmes started his PhD studies in the Department of Bioengineering at the University of Washington in 2014.
He previously obtained both of his bachelor's degrees,in Biomedical Engineering and Electrical Engineering, from
Michigan Technological University in 2013. Hal was named a Goldwater Scholar in 2011 and recieved a National
Defense Science and Engineering (NDSEG) Fellowship in 2014. He also holds a position as an Engineering Fellow at
Conservation X Labs. His research interests include the use of MEMS and microfluidic devices for biology and conservation
Di Sun
Di Sun is a PhD student in the Department of Electrical Engineering at University of Washington since 2014.
He graduated from Xi'an Jiaotong University with a bachelor degree. He then finished his Master of Science degree
at Case Western Reserve University, focusing on non-hermetic packaging technology for implantable MEMS devices.
He joined Prof. Karl F. Böhringer's MEMS research group at University of Washington and his research topic involved
with self-cleaning surface technology based on microfluidic devices. He was a Clean Energy Institute (CEI) fellow
in 2017 and awarded with a CEI fellowship.
Zheyi Han
Zheyi is an international student from China and is currently pursuing a Ph.D. degree in the Department of Electrical Engineering.
She has earned her Bachelor’s degree in Materials Science and Engineering at Cornell University and her Master’s degree in the same major at
the University of Washington. Besides painting and reading, Zheyi volunteers regularly at the Pacific Science Center when she is off school
or work. You may meet her in Tinker Tank or any Virtual Reality exhibits on the weekends!
Ana Gomez
Ana E. Gomez has been an undergraduate in the Department of Bioengineering at the University of Washington. She is a Ronald E. McNair Scholar.
Her research interests include microfluidic devices for biology and conservation.
