Stéphanie Valleau recently completed a postdoctoral fellowship at Stanford University, sponsored by the Simons Collaboration on Origins of Life. Stéphanie works at the intersection of chemical engineering, computer science and biophysics. Her research centers on the connection between long-term changes — biological evolution, environmental changes, transport in large networks of reactions — and short-timescale chemical transport processes, such as single-reaction kinetics and exciton transport in single complexes. Using machine learning models to understand which features maximize efficiency and how they are interconnected will enable more rapid design of better reaction networks, clean energy materials, catalysts and more.

Most recently, in collaboration with the Simons Foundation, Stéphanie has been employing large graphical processing unit computer clusters to investigate the formation of amino acids, nucleotides and lipids — the building blocks of life. While at Harvard, she received the American Chemical Society’s Graduate Student Award in Computational Physical Chemistry, which gave her access to 100,000 hours of computing time on Blue Waters, one of the most powerful supercomputers in the world.
