Chemistry at Illinois University of Illinois at Urbana-Champaign

Roman Boulatov

Assistant Professor of Chemistry

Roman Boulatov received his undergraduate degree from the University of St. Petersburg in 1996 and his Ph.D. from Stanford University in 2002. After completing his postdoctoral at Harvard University, Roman joined the University of Illinois in the spring of 2005. His research is in a highly-multidisciplinary area of energy transduction at the molecular, supramolecular, meso- and macroscopic scales. He is particularly interested in experimental synthetic studies of the basic principles of chemomechanical energy transduction.

Research

We study the effect of force on rates of localized chemical reactions. We are motivated by the increasing need to model quantitatively multiscale phenomena, such as directional translation of a microscopic object by structural changes in a reacting (macro)molecule (molecular propulsion), fragmentation of polymers in shear flows or on clean surfaces, propagation of cracks in polymers and operation of motor proteins. Being unsatisfied with the limited resolution of conventional force spectroscopies, we developed our own approach which uses molecular force probes to generate restoring forces in structurally diverse functional groups. Our work combines organic and inorganic synthesis, physical characterization and quantum-chemical calculations providing an opportunity for group members to gain broad expertise in methods of modern chemical science.
