Dr. Samuel Kassegne

Bio

Dr. Sam Kassegne holds a Ph.D. degree in engineering mechanics from Virginia Polytechnic Institute and State University. His research interests are in the areas of MEMS, bio-nanoelectronics, and integrated micro- and nano-fabrication technologies. His experimental research work is focused primarily in Organic-MEMS, novel applications of microfluidics/nanofluidics and microarray technology, new bio-nanoelectronics platforms, as well as polymer photovoltaic technology. His lab has a strong focus on developing the next generation of integrated micro- and nano-lithography technology for a variety of application areas. Other focus areas include MEMS-based IMUs.

Dr. Kassegne has an extensive industrial experience in MEMS, biotech and computational sciences acquired through his employment at Nanogen, Microfabrica and Bentley Systems in Southern California. He also has consulted for the following companies: Corning/Intellisense, SAIC, Nevada Nanotech, OxyHeal, ERC, OmniTech, KeyMark Engineering, Game Changers, Cooley LLP, and Nokia. Further, as evidenced by the breadth and depth of his publication records and the companies he has consulted for, Dr. Kassegne has a unique engineering background that spans a number of engineering disciplines.

Dr. Kassegne's research has been funded by the National Science Foundation, San Diego Foundation, CSUPERB, AlphaTec, and Amco (Korea). He has also taught MEMS & FEA courses at UCSD and UCI where he was a visiting scientist at Marc Madou's Lab.
