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.
April 6-9, 2017 - Laura has organized the first annual Southeastern Single Molecule Biophysics Networking Meeting, to be held at Amicalola Falls Lodge in Georgia's Chattahoochee National Forrest. For more information see the meeting website: www.southeastsm.org.
Feb 13, 2017 - Yan Yan gave a platform talk at the annual Biophysical Society meeting in New Orleans, entitled "Protein-mediated Loopts in Supercoiled DNA Create Large Topological Domains". For more information check out the abstract (DOI:10.1016/j.bpj.2016.11.938).
Dan Kovari and Zsuzsanna Vörös also gave poster presentations at the meeting. You can find Dan's abstract here (DOI: 10.1016/j.bpj.2016.11.421), and Zsuzsanna's here (DOI: 10.1016/j.bpj.2016.11.1169).
Spring 2016 - Laura is editing a Special Issue of Biophysics Reviews entitled “DNA supercoiling, protein interactions and genetic function”. The Issue will appear in early September and will contain contributions by Travers and Muskhelishvili; Levens, Baranello and Kouzine; Corless and Gilbert; Ordu, Lusser and Dekker; Ma and Wang; Dorman; Seol & Neuman; Higgins; Fenfei Leng; Laura Finzi and David Dunlap; Perez and Olson; Harris, Noy and Sutthibutpong.
