There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Prof. Ralph Jimenez, University of Colorado at Boulder
Ultrafast spectroscopy and microfluidics-based methods for investigating protein dynamics
Physical Chemistry Seminar Series
My group develops optical methods to quantify biophysical phenomena such as protein dynamics and cellular mechanical properties, and biotechnologically-relevant problems such as photosynthesis and lipid accumulation in algae.
In this seminar, I will discuss one perspective on the importance of sub-nanosecond conformational fluctuations of proteins, and describe development of new methods for measuring dynamics and conformational heterogeneity with femtosecond spectroscopy. I will also describe new microfluidics-cytometry based methods for measuring the photophysical properties of red fluorescent proteins, and the prospects for a âmolecular evolutionâ approach to improving the photobleaching properties of these molecules employing a cell-sorter.
