Welcome

Welcome to the Blank Research Group in the Chemistry Department at the University of Minnesota.

Our research group investigates a variety of dynamic events in condensed media. The investigations range from basic chemical reaction dynamics in solution to energy and charge transfer dynamics in new materials with targets including applications in solar energy conversion. Our primary experimental tools are nonlinear time domain spectroscopies and this includes new methods developed in our laboratory. Computational tools such as time dependent density functional methods and molecular dynamics simulations are used to complement the experiments and aid in the interpretation of our data.
