Sergei Tretiak

Biography

Sergei Tretiak received his M.S. (highest honors, 1994) from Moscow Institute of Physics and Technology (Russia) and his Ph.D. (1998) from the University of Rochester (US) where he worked with Prof. Shaul Mukamel. He was then a Director-funded Postdoctoral Fellow in Theoretical Division at Los Alamos National Laboratory (LANL) and became LANL staff scientist in 2001. Since 2006, he is a staff scientist at Center for Integrated Nanotechnologies (CINT), a DOE user facility at LANL/SNL. Sergei Tretiak received the LANL 2010 Fellow’s Prize for Research. His research interests include development of modern computational methods for molecular optical properties, nonlinear optical response of organic chromophores, adiabatic and non-adiabatic molecular dynamics of the excited states, optical response of confined excitons in conjugated polymers, carbon nanotubes, semiconductor nanoparticles, and molecular/biological aggregates. He has published over 150 papers, that have been cited over 5000 times (h-index of 42), and has given over 120 invited talks and seminars in the US and abroad.
