My research spans a large variety of frustrated constraint satisfaction problems that range from computer science to geometry, but are all inspired by physical systems such as folding proteins, colloidal suspensions, granular beds, and spin glasses. I have been working on developing a unified view of these systems by employing both information theoretical and statistical physics approaches. The work has contributed to the development of the "divide and concur" scheme, a novel general numerical approach for solving constraint satisfaction problems. In addition to the general questions regarding these systems, I am also interested in answering the specific questions that raise themselves in these fields.
