Vita

Dr. Tak-Sing Wong received his Ph.D. degree (under the guidance of Prof. Chih-Ming Ho) specializing in MEMS/Nanotechnology in the Mechanical and Aerospace Engineering Department at UCLA in June 2009, following his B.Eng. degree (under the guidance of Prof. Wen J. Li) specializing in robotics and manufacturing technologies from the Chinese University of Hong Kong in May 2003.  He has authored/co-authored 22 papers in archival journals (11) and peer-reviewed conference proceedings (11), a book chapter, and has a pending U.S. patent, all in the area of MEMS, nanotechnology, and interfacial phenomena.  He is the recipient of the Lucent Global Science Scholar Award (1 of 108 selected worldwide) and the Intel Foundation Ph.D. Fellowship (1 of 30 selected in the United States in 2007).  He received a full scholarship to participate the Complex Systems Summer School 2008 co-organized by the Santa Fe Institute, USA and the Institute of Theoretical Physics, The Chinese Academy of Sciences.  In addition, his research work in nanomanufacturing technologies has garnered best paper awards from IEEE local (Hong Kong), regional (Asia-Pacific), and International (Nano’03) student paper contests.  His current research interests are micro/nanomanufacturing, micro-electro-mechanical systems, nanoscale interfacial phenomena, and physical biology.

My current research interests include micro and nanomanufacturing, MEMS, nanoscale interfacial phenomena, and physical biology.  During my graduate study at UCLA, I have contributed to the development of a variety of micro and nanomanufacturing technologies, such as a micromachining technique for patterning silicone elastomer (Sensors & Actuators B 116, 2 – 10, 2006 & a U.S. provisional patent) and an integrated top-down/bottom-up manufacturing platform for molecular proteins assembly (Soft Matter 3, 541, 2007, cover image article, IEEE Nano’07 & IEEE Review).  Integrated systems, such as a chemical vapor sensing array and a microfluidic actuator (IEEE MEMS’05, Transducers’05, ISOEN’05), as well as an integrated magnetic cell separation system (J. Micromech. Microeng. 17, 1299, 2007, & a U.S. patent pending), were manufactured through the use of innovative micro/nanomanufacturing technologies.  Furthermore, I am interested in developing new experimental techniques to solve fundamental and challenging scientific problems in nanoscience, particularly in nanoscale wetting phenomena (Langmuir 25, 6599, 2009, top 20 most accessed article in June 2009).  On the other hand, I have developed a theory in explaining surface wetting phenomena in biological and artificial surfaces (Langmuir 25, 12851, 2009).  More recently, I have shifted my focus into bio-inspired and complexity engineering, with the aim to develop novel bio-inspired engineering devices and systems using the concepts learned from the natural complex systems.
