Our research is focused on the elucidation of the molecular mechanisms of transcriptional regulation. We use single molecule techniques such as the tethered particle motion technique (TPM), magnetic tweezers (MT), atomic force microscopy (AFM) and single molecule fluorescence together with more traditional biochemical and biomolecular techniques. We develop instrumentation and computational analyses as needed to carry out our investigations. Our research interests span loop-based genetic switches, transcription roadblocks, the interplay between transcription and DNA supercoiling, topoisomerases and DNA mechanics.
