Research Statement

Designing optimal catalysts, clean energy materials and reactivity is at the heart of chemical engineering. Finding the features which maximize the efficiency of chemical transport processes, catalyst activity and so on, can enable us to define new tools for more rapid chemical design.

In the Valleau group, we aim to search for these features and to address the questions of reactivity, exciton transport and material design by combining and developing methods from different fields: computational chemistry, biophysics and computer science. Among our goals, we want to understand how long term changes, such as biological evolution and temperature variations influence short timescale chemical transport processes.
