Research Interests:

Microelectromechanical systems (MEMS), microsensors, microactuators, microsystems and micromachining; magnetism and magnetic materials; neuroengineering and neuro-silicon interfaces; distributed sensors, actuators and information.

Technical Research Interest:

Prof. Judy and his research group work in two fields: (1) novel nano- and micro-electro-mechanical systems (NEMS/MEMS) and (2) application of state-of-the-art engineering technologies to brain research, a field now called neuroengineering. Specific NEMS/MEMS research activities include ferromagnetic NEMS/MEMS for physical actuation and sensing at many levels of scale and miniaturized chemical-sensing systems. Examples include ferromagnetic actuators for optical, RF, and biomedical applications and micromachined electrochemical nitrate sensors with integrated microfluidics. His lab is also actively investigating the scaling limits of ferromagnetic actuators through a study of nanomagnetomechanical devices. Specific neuroengineering research interests include technologies for improving brain-computer interfaces, such as multi-electrode neural microprobes for neural recording and stimulation and miniature wireless neural transceivers. The neural-probe technologies are being used for deep-brain-stimulation applications, such as Parkinson's disease research. The wireless neural transceivers are being developed for a wide range of behavioral and neurophysiological research projects. In addition, some research projects bridge his lab's two broad research fields NEMS/MEMS and neuroengineering. Examples include nanomachined single-cell patch-clamp instruments with integrated microfluidics and clog-resistant MEMS-enabled hydrocephalus shunts.

Additional Information:

Micromachining and microelectromechanized systems (MEMS).

Dr. Judy received the B.S.E.E. degree with summa cum laude honors from the University of Minnesota, Minneapolis, MN, in 1989, and the M.S. and Ph.D. degrees from the University of California, Berkeley, CA, in 1994 and 1996 respectively. His doctoral research concentrated on the merger of thin-film magnetic-recording head fabrication techniques and technologies with those used in the IC industry, to produce novel MEMS devices.

He worked for Silicon Light Machines, Inc., Sunnyvale, CA, a startup company commercializing a MEMS-based optical-projection system for digital-display applications, from 1996 to 1997. He joined the faculty of the Electrical Engineering Department at the University of California, Los Angeles, in 1997, where he is currently an Assistant Professor. He serves as Chair of the MEMS ad hoc major field in the EE Department, and as Chair of the Neuro-Engineering major field in the Biomedical Engineering Interdepartmental Program.

His research interests are in micromachining and MEMS technologies, including microsensors, microactuators, microsystems, and their biomedical applications.
