Tsen's research interest focuses on the interaction of light with solid state and biological systems in particular, on the use of ultrafast laser sources to elucidate novel electron transport phenomena, dynamical properties of lattice vibrations in low-dimensional and nanostructure semiconductors as well as microscopic mechanisms in biological systems such as viruses, bacteria and cells. He has more than 160 publications and has edited 4 books in the area of ultrafast phenomena in semiconductors. Books edited: (1) Ultrafast Phenomena in Semiconductors published by Springer-Verlag (New York,2001). (2) Ultrafast Physical Processes in Semiconductors, published by Academic Press as the book Volume #67 in the series - Semiconductors and Semimetals, edited by R.K. Willardson and E.R. Weber(New York, 2001). (3) Ultrafast Dynamical Processes in Semiconductors, published as the book Volume #92 in the series - Topics in Applied Physics, by Springer-Verlag (Heidelberg, 2004). (4) Non-equilibrium Dynamics of Semiconductors and Nanostructures, published by CRC Press Inc. (New York, 2005).
