Professor Liwei Lin received his Ph.D. degree from the University of California, Berkeley, in 1993 and is Chancellor’s Professor at the Mechanical Engineering Department and Co-Director at Berkeley Sensor and Actuator Center, an NSF/Industry/University research cooperative center. He served as the Vice-Chair for graduate study for the Mechanical Engineering department from 2006~2009. His research interests are in design, modeling and fabrication of micro/nano structures, sensors and actuators as well as mechanical issues in micro/nano systems including heat transfer, solid/fluid mechanics and dynamics. Dr. Lin is the recipient of the 1998 NSF CAREER Award for research in MEMS Packaging and the 1999 ASME Journal of Heat Transfer best paper award for his work on micro scale bubble formation. He led the effort in establishing the MEMS sub-division in ASME and served as the founding Chair of the executive committee for the MEMS division in ASME. He holds 15 U.S. patents in the area of MEMS and NEMS.
