Biochemistry

Our lab studies single molecule biophysics using scaning probe methods. The idea is to measure and manipulate individual molecules. The premise is that single molecules are simple enough to (eventually) be modeled accurately with computer simulations, yet, in a real environment, complex enough to reflect the variations that are important to their function. Projects include (a) A study of gene transcription using single molecule models of a gene promoter, (b) studies of conduction in single molecules aimed at laying the groundwork for molecular electronics and (c) development of new sngle molecule measurement techniques.
