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, polymer photovoltaic technology, bionanoelectronics,
and NeuroMEMS. His lab has a strong focus on developing the next generation
of integrated micro- and nano-lithography technology for a variety of application
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 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 variety of engineering disciplines.
Dr. Kassegne's research has been funded by the National Science Foundation, DoE, DoD (SPAWAR), San Diego Foundation, Amco (Korea), and others.
We are a research group in the Mechanical Engineering Department of San Diego State University in southern California. Our diverse team of researchers includes mechanical, chemical, and electrical engineers as well as bioengineers. Our research areas include MEMS, micro- and nano-fabrication, bionanoelectronics, microfluidics/nanofluidics, polymer-based photovoltaic technology, and computational sciences. Our group collaborates with researchers at our institution and other national MEMS programs (including the various academic and industrial groups that spun-off the core Nanogen technology). We also have an active international program involving seminars and exchange vists. Our extended class 100 cleanroom facility (MicroFab & NanoFab Facility) (1600 sq. ft.) is equipped for most lithography processes including metal desposition, dry (DRIE) and wet etching, soft lithography, as well as characterizations including 0.25 micron resolution deep UV lithography capability with Micrascan III step and scan litho system. We also have a brand new 400 sq.ft. organic solar processing, packaging and testing facility.

We are working on innovative hierarchical micro- and nano-fabrication technologies. One approach we are pursuing is IMN-litho (Integrated Micro/nano) lithography that shows promise in machining chips with both micro and nano features on the same substrate. Potential applications include bio-chips, sensors, microfluidic chips, and microarrays with a hierarchy of feature sizes starting from nanometer-level to sub-micron, micron and sub-mm interface to the outside world.
