Assistant Professor & Director of MEMS Research Lab, ME Dept., SDSU.

General Introduction

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, integrated micro- and nano-fabrication technologies, and bio-nanoelectronics. 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 as well as consultancy work for Corning, SAIC, Nevada Nanotech, OxyHeal, and Nokia. His 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.

Summary of Research

We are a research group in the mechanical engineering department of San Diego State University in southern California.  Our team includes mechanical, biomedical, chemical, electrical as well as materials engineers.  Our research areas include MEMS, micro- and nano-fabrication, bio-nanoelectronics, microfluidics/nanofluidics, polymer-based photovoltaic technology, emerging technologies in IMUs (applications in cell phone, navigation systems, and image stabilization), and computational sciences (modeling multi-physics and reaction engineering in life sciences and electrochemical systems). 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 joint research. Our new class 100 cleanroom facility (400 sq. ft.) is equipped for most lithography processes as well as some characterizations including 0.25 micron resolution deep UV lithography capability with Micrascan III step and scan litho system.

Current Group Members: Neeraj Yadav, Bhuvnesh Arya, Nithesh Paramesh, Nitin Hardwood, Gunay Ozturk, Namratha Tata, Vinot Vijayaraghavan, Anson Hsu, Mihir Parikh, Krishna Desai, Chintan Patel, Neha Chowdhry, Anurag Kaushik, Abhishek Khatri, Beejal Mehta, Nasim Vahidi, Mohammad Rayatparvar, and Mohammad Majzoub.

(I) Bio-Nanoelectronics Group

This group is investigating the feasibility and long-term stability of bio-nanoelectronics architecture based on our existing microarray platform. The architecture comprises of DNA molecular wires and interconnects attached to carbon microelectrodes. The boarder impact of this study is in developing nanoscale modulation of electrochemistry and electric-fields that will form basis for advancing our knowledge in large-scale bio-nanoelectronics as well as electrochemistry and electrostatics at a sub-micron-scale.

Researchers: Anson Hsu, Mohammad Rayatparvar, Neha Chowdhry, Nasim Vahidi, and Beejal Mehta.

(II) Polymer Solar Cell Group (link)

Using a hybrid bottom-up and top-down micro/nano fabrication approach, we are developing new generation of polymer-based solar cells and OLED with new electrode materials and architecture. The group also uses computational photovoltaics to develop new insights and fundamental understanding of interfacial issues between phtoactive layers and electrode materials.

Researchers: Mohammad Majzoub, Gunay Ozturk, Mihir Parikh, Krishna Desai, Anurak Kaushik, and Chintan Patel.

(III) Nanofabrication Group

We are working on innovative hierarchical micro and nanofabrication 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.


Collaborators: Dr. Moon and Morsi @ SDSU.

(IV) Computational Group

We have very active research in (i) computational electrochemsitry for micro- and nano-electrochemical systems, and (ii) computational photovoltaics to drive our experimental work in organic PV technology.

Researchers: Bhuvnesh Arya, Neeraj Yadav.

(V) IMU Group (Accelero & Gyro)

We are working on novel tunable 2-axis and 3-axis MEMS accelerometers & gyroscopes. An ongoing research project has a wide application in cell phones, gaming, energy harvesting, and image stabilization.
