Roger T. Howe is the William E. Ayer Professor in the Department of Electrical Engineering at Stanford University, as well as the Faculty Director of the Stanford Nanofabrication Facility. He earned a B.S. degree in physics from Harvey Mudd College, Claremont, California and an M.S. and Ph.D. in electrical engineering from the University of California, Berkeley in 1981 and 1984. After faculty positions at Carnegie-Mellon University in 1984-1985 and the Massachusetts Institute of Technology from 1985-1987, he returned to Berkeley where he was a Professor until 2005.
His research interests include micro electromechanical system (MEMS) design, micro/nanomachining processes, and self-assembly processes. A major focus of his research from the early 1980s until recently was technologies for integrated microsystems, which incorporate both silicon integrated circuits and micromechanical structrures. Recently, his research has shifted to nano electromechanical systems (NEMS), for applications ranging from chemical sensors to relays and logic devices. Prof. Howe has made contributions to the design of MEMS accelerometers, gyroscopes, electrostatic actuators, and microresonators. He was elected an IEEE Fellow in 1996, was co-recipient of the 1998 IEEE Cledo Brunetti Award, was elected to the U.S. National Academy of Engineering in 2005. In 2015, he was co-recipient of the inaugural IEEE Electron Devices Society Robert Bosch Micro and Nano Electromechanical Systems Award for his contributions to MEMS processes, devices, and systems and the 2015 IEEE Electron Devices Society Education Award. He was a co-founder of Silicon Clocks, Inc., a start-up company that commercialized poly-SiGe integrated MEMS-on-CMOS for timing applications, which was acquired by Silicon Laboratories, Inc., in April 2010. In December 2015, he co-founded ProbiusDX based on research in his group on label-free biomolecular sensing platforms.
In December 2009, he became the Faculty Director of the Stanford Nanofabrication Facility. From 2011 - 2015, he was the Director of the National Nanotechnology Infrastructure Network (NNIN).

Dr. Chaitanya Gupta (PhD, Chemical Eng. UIUC, 2009; MSc, Physics UIUC, 2009; MSc, Chemical Eng. UIUC, 2007; B.Tech, Chemical Eng. IIT-Delhi, 2001)
My research interest is designing and engineering devices at the meso-scale, where quantum and classical phenomena co-exist. These devices exhibit characteristics that can be leveraged for new applications, as well as for improving the performance of existing sensors. The specific research goal is to engineer a platform that mimics the function of the olfactory receptor that is responsible for the sense of smell. Though our understanding of how the sense of smell works is still incomplete, recent theoretical and experimental evidence indicates that the olfactory receptor protein function not a traditional lock-and-key mechanism, but rather mimics a nanoscale MIM structure. Tunneling currents in MIM structures at low temperatures contain information on the molecular bonds in the insulator molecule. By suppressing noise at the sense electrode using voltage feedback, vibrational spectra of analyte molecules have been measured at room temperature in a nano electrochemical system. This project has many facets, including sensor design and fabrication, sample preparation, and signal acquisition and interpretation.
