Ph.D., Physics, Univ. of California, Berkeley, 1996

Research Statement:
My interest is in using physical concepts and experimental techniques to study fundamental questions in molecular biology. The biological systems under study include helicases that unzip DNA, DNA recombination intermediate called Holliday junction and its associated enzymes, folding and catalysis of hairpin and VS ribozymes, DNA replication machinery, and chromatin remodeling complexes. Our main experimental tool is single-molecule fluorescence spectroscopy and microscopy, supported by nano-mechanical tools such as magnetic and optical tweezers.
Research Interests:
  • DNA-protein and protein-protein interactions, protein and RNA folding, membrane biophysics, fluorescence microscopy of biological systems, single molecule spectroscopy and manipulations, biologically inspired nano-mechanical devices, RecA.
  • Ph.D. Thesis Title: Fluorescence spectroscopy of single molecules at room temperature and its applications.
Undergraduate Research Opportunities:
My lab reaches out to undergraduate students and over the years I have tutored over 12 undergraduate students who have gone on to apply for graduate schools, either at Illinois or other universities. Currently, there are several physics undergraduate students who are working on projects in my lab, including engineering a helicase mutant that reverses its natural direction of movement, and two computer science undergraduate students who are writing codes for super-resolution imaging. One of the missions of the Center for the Physics of Living Cells is to tutor the next generation of scientists in the physics of living cells, thus we have an active group of undergraduate students working on various aspects of this important vision.
