Biographical Sketch

Junhong Chen got his B.S. degree (in Thermal Engineering) in 1995 at Tongji University, and his M.S. degree and Ph.D. (both in Mechanical Engineering) in 2000 and 2002, respectively at University of Minnesota. He is currently a tenured Associate Professor in the Department of Mechanical Engineering at the University of Wisconsin-Milwaukee (UWM). His research interest lies in nanoparticle synthesis, assembly, and nanofabrication; carbon nanotubes (CNTs) and hybrid nanomaterials; nanostructure-based gas sensors and biosensors; energy conversion, conservation, and renewable energy; sustainable environment and pollution control; corona discharges and plasma reacting flows. Since his postdoctoral research at California Institute of Technology (Caltech) in Chemical Engineering during 2002-2003, Junhong Chen has been working on the synthesis and assembly of various nanomaterials for application in electronic devices, particularly for targeting sustainable environment and energy. He has developed a simple and versatile mini-arc plasma source for synthesis of nonagglomerated nanocrystals of a variety of materials with controlled size. He has invented a material-independent dry technique to efficiently assemble nanocrystals onto CNTs with considerable control. The resulting nanocrystal-CNT structures provide tremendous new opportunities for nanoscience and nanotechnology applications, such as in gas sensors, biosensors, solar cells, environmental remediation, nanoelectronics, catalysis, and nanomanufacturing. The novel technique has been highlighted by Nanowerk Spotlight. He has also developed a new approach to characterize the interaction between the nanocrystal and the CNT, which has been featured on the cover of journal NANO. His work on a novel gas sensor based on hybrid nanocrystal-CNT structures have recently been demonstrated and published by Advanced Materials. And his another work on hybrid nanomaterials has been featured on the UWM front page, Science Daily, PhysOrg, Photonics Online, Nanowerk, Bio-Medicine, EurekAlert, Nanotechnology Now, and the A to Z of Nanotechnology. He has been invited for talks at University of Minnesota, University of Wisconsin-Madison, Northwestern University, Tongji University, China, University of Notre Dame, Naval Research Lab, Xerox Corporation, TSI Incorporated, and SME Nanomanufacturing Conference. His research is sponsored by US National Science Foundation (NSF), Environmental Protection Agency (EPA), Argonne National Laboratory (ANL), Xerox Corporation, Miller Electric Manufacturing, UW-System, WiSys Technology Foundation, UWM Research Growth Initiative (RGI), and UWM Research Foundation. His research has also been recognized by the 2008 Graduate School/UWM Foundation Research Award.
