Tretiak, Sergei

An exceptionally creative chemical physicist. The overarching theme of his research is to develop a theoretical framework for electronic properties in complex molecular structures. These materials are at the center of current scientific research, with potential applications in photonics, displays and sunlight harvesting, such as photovoltaic devices based on organic and organic–inorganic active materials. His numerous significant contributions to the understanding of optical processes in advanced, reduced-dimensional materials are being developed for optoelectronics applications. His theoretical studies have provided extremely important descriptions of photo-physical-chemical phenomena in novel molecular systems. The suite of powerful theoretical techniques and elaborate codes that Tretiak developed has substantially influenced the way computational materials chemistry is currently studied worldwide. He is one of the world leaders in understanding non-linear excitations, such as in optical materials. Tretiak has mentored and trained more than 20 postdoctoral associates and 80 summer students, and he won the LANL Postdoctoral Distinguished Mentor Award in 2015. He is a world-leading electronic structure theorist who has transformed optical material science to enable next-generation energy systems.
