Weintraub Award to Daniel Hochbaum (2/2014)
Daniel Hochbaum has been awarded the Harold M. Weintraub Graduate Student Award
for outstanding achievement during graduate studies in the biological sciences. Not bad for a physicist!
Absolute Voltage (2/2014)
Jen and Veena discovered how to measure absolute membrane voltage via rhodopsin photocycle dynamics. Read about it in Biophysical Journal
. See also a nice commentary
from Jim Spudich. Cheers to Jen and Veena!
A flash of memory! (1/2014)
Veena and Daan's paper on Flash Memory
came out in JACS. They showed how one could store a long-lasting photochemical imprint of neuronal activity in a microbial rhodopsin. This suggests a path to whole-brain neural recording, though there's still a lot of work to do.
Spiking HEKs (1/2014)
We made a line of non-fluorescent HEK cells that produce spontaneous electrical spikes in confluent culture. They produce beautiful waves and spiral patters of electrical activity. Shocking! These are great for testing prospective fluorescent voltage indicators. The paper
is in PLoS One. Congratulations Jeehae and Kit!
Welcome to Xin and Yoav (12/2013)
Two new postdocs joined the lab. Yoav comes from the lab of Adi Mizrahi at Hebrew U. Yoav will be looking at optical electrophysiology in mouse brains. Xin Tang comes from the lab of Taher Saif at UIUC. Xin will study bioelectric and biomechanical effects outside the nervous system. Welcome both!
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!
