Research Interests

back to top

Professor Lu obtained his B.Eng. degree in 1984 from Tsinghua University, Beijing, China. He received his M.Eng. and Ph.D. degrees from Osaka University, Japan in 1988 and 1991, respectively. Upon graduation from Osaka University, he joined the Department of Electrical Engineering at National University of Singapore where he served various positions. He joined the Department of Electrical Engineering at the University of Nebraska-Lincoln in September 2002.

He has an extensive research background in the areas of laser-based microscale and nanoscale material processing. Professor Lu has over 150 peer-reviewed journal publications and over 160 presentations in international conferences. He also received a number of national and international awards, including National Technology Award (Singapore, 1998), Asean Engineering Achievement Award (Asean Engineering Association, 1999), and Laser International Award (Germany, 2000). He has led the research group that pioneered laser removal of nanoparticles from solid surfaces (commonly known as laser cleaning) and nanoscale patterning by optical resonance in microparticles. He was among the first researchers to theoretically propose a model to explain the behaviors of nanoparticles on solid surface under laser irradiation, and experimentally obtained the sub-wavelength nanostructures using laser-induced optical resonance in nanospheres. His work encompasses a few important topics including laser writing of sub-wavelength structures, applications of laser removal of nanoparticles, behaviors of nanoparticles under laser irradiation, theoretical modeling, influence of laser wavelength, and particle removal with assistance of thin liquid films. He has also closely worked with industries and developed a few commercial products for laser etching, laser cleaning, laser cutting and laser surface texturing.
