http://www.fas.harvard.edu/~aecohen/  Research Interests:  Our
effort is split between developing new physical tools to probe
wet, squishy molecules and cells, and using our tools to make
new measurements. We choose problems by looking in unexplored
regimes of time and space; we combine nanofabrication, lasers,
microfluidics, electronics, biochemistry, and computers to
generate data; and we apply statistics and physical modeling to
understand the data.  Research in the lab falls roughly into 3
areas:  Single-molecule Biophysics  We developed a machine
called an Anti-Brownian Electrokinetic trap (ABEL trap) that can
immobilize a single fluorescent molecule in solution, without
any physical tethers.  The ABEL trap works by tracking the
Brownian motion of a single molecule using fluo
