Bio Sketch: Dr. Howard Wang obtained his Bachelor of Science in
Physics from the Peking University in 1992, and received his Ph.D. in
Materials Science and Engineering from the University of Pennsylvania
in 1999. After completing his postdoctoral research at the National Institute
of Standards and Technology, Wang joined the Department of Materials Science
and Engineering at the Michigan Technological University as an Assistant
Professor in 2002. Wang moved to Binghamton University in 2006.
Dr. Wang's research focuses on materials aspects of advancing nanotechnology
and biotechnology. His interdisciplinary research program integrates nanomaterials
synthesis, characterization, processing, and application. His group's
recent studies involve synthesizing carbon nanotubes, metal oxide nanowires,
metal nanoparticles, dispersing nano-objects in solutions, gels, polymers
and ceramics, assembling them into ordered structures, and fabricating
flexible electronics, nanocomposites and biosensors for applications
