Sukrit’s research focuses on applying photochemistry to questions related to the origin of life on Earth and the search for life on other worlds. These questions are coupled: efforts to understand the origin of life on Earth helps guide our search for it elsewhere in the cosmos, while observations of other planets help us test our theories of the prebiotic environment and of abiogenesis. To understand abiogenesis, Sukrit works to constrain the palette of environmental conditions from which life arose on Earth, to test and guide experimental studies of the origin of life. To search for life elsewhere, Sukrit works to determine observational tests by which life on other worlds may be remotely discriminated. In collaboration with experimental colleagues, Sukrit works to obtain the critical measurements of fundamental photochemical parameters required to build robust models in support of both goals.
