Physical tools to study molecules, cells, and organisms
We invent new physical tools to probe biological structures. Then we use our tools to make new measurements. We choose problems by looking in unexplored regimes of time and space; we combine protein engineering, lasers, nanofabrication, microfluidics, electronics, biochemistry, and
computers to generate data; and we apply statistics and physical modeling to understand the data.
Doctor! Doctor! (10/2013)
Congratulations to Jen and Min Ju for defending their PhD theses! Jen's topic was "Dynamics in Biological Soft Materials," and Min Ju's was "Trapping and Manipulating Single Molecules of DNA". We will miss you both!
New faces in lab (9/2013)
Jonathan Gootenberg joins as a rotation student, continuing the proud tradition of our lab importing our brains from MIT. Miao-Ping Chien joins as a postdoc from UCSD. Miao-Ping comes from Nathan Gianneschi's Lab at UCSD, where she worked on stimulus-responsive nanomaterials and drug delivery. Here she'll be helping us see what we feel. Shan Lou joins as a postdoc from Qiufu Ma's lab at the Dana Farber Cancer Institute, where she worked on the sense of touch. Here she will be imaging electrical activity in peripheral nerves. Welcome all!
Check out our kinky genes! (8/2013)
Alex's paper on Euler buckling and nonlinear kinging in double-stranded DNA
was just published in Nucleic Acids Research. Nice work, Alex!
Adam appointed HHMI Investigator (5/2013)
The Howard Hughes Medical Institute selected Adam as one of its new investigators
. Thank you Mr. Hughes!
Alex defends thesis (5/2013)
Alex passed his thesis defense with an elegant discussion of the ABEL trap, and also recent work on DNA mechanics. Congratulations Dr. Fields!
Welcome to Vedha Nathan (5/2013)
Vedha Nathan is joining the lab as a Research Assistant. She comes with many years of experience working in Howard Berg's lab. Welcome Vedha!
Arch photophysics (3/2013)
Archaerhodopsin 3 (Arch) acts as a fluorescent reporter of membrane voltage. But how does it work? Dougal, Veena, and Hohjai elucidate the mechanism
Twisty nanowires (1/2013)
Yiqiao's paper on chiroptical effects in twisted nanowire plasmonic oscillators
came out in Applied Physics Letter. A nice twist to finish your thesis.
Welcome Maggie! Thank you Jeff! (1/2013)
Maggie Kenar is taking over the administrative management of the lab from Jeff Fosdick. Thank you for all your help Jeff, and welcome to the family, Maggie.
Doctor, Doctor! (12/2012)
Congratulations to Yiqiao and Nan for successfully defending their PhD theses. First two students to graduate from the group. Nice work, guys!!
Popular Scientist (10/2012)
Adam features in this month's issue of Popular Science
as one of their "Brilliant 10". I never won a popularity contest before!
Optimal tracking of a Brownian particle (9/2012)
Congratulations to Alex on his recent paper in Optics Express
! The paper explains the theory of how to do as good a job as possible tracking a dim, quickly diffusing object.
Nice dimples -- paper in JACS (8/2012)
Min Ju's paper on trapping single molecules in nanoscale dimples will appear as an article in JACS
. Nice work Min Ju!
