Hung-Sheng Chiang, research associate

Hung-Sheng is currently a Research Associate in the Department of Electrical and Computer Engineering. He has been working on building and characterizing passively phase-locked fiber laser arrays. He experimentally demonstrated Kramers-Kronig self-phasing in this laser architecture. Recently, his research is shifting from CW lasers towards pulsed lasers. He envisages a new class of pulsed lasers that are powerful enough to ignite nuclear fusion reactions or serve as the building blocks of next-generation particle accelerators. He completed his PhD degree in Physics in 2011 here at University of Minnesota Twin Cities. He specializes in condensed-matter physics.

Di Lin, post-doc

Di received his B.S. in electrical engineering from the University of Minnesota in 2008. In 2015, he completed his dissertation on the metrology and design of gradient-index optical materials at the same institution and received his Ph.D. in electrical engineering. His current research involves image retrieval algorithms using information from indirect photons and the application of inverse methods.
