Professor & Canada Research Chair @SFUPhysics. Nonequilibrium statistical biophysics
Joined January 2019
This was a stimulating and quite enjoyable melding of experiment and theory. Special salute to lead author Takahide Mishima and the rest of @TohokuBiophys, former postdoc @PhyDeepak, and current grad student Callum Wareham @SFUPhysics. Thanks to support @NSERC_CRSNG @TIPS_SPIIE

Is it more efficient to push a molecular motor with a constant force, or at a constant velocity? See our collaborative paper just out in @PhysRevLett (and the accompanying Focus article) to learn the winner, and the why (it’s all about the fluctuations).
Our new PRL paper was featured in Physics Magazine by APS. It was a joyful and stimulating collaboration with @DavidASivak group. https://t.co/9X39uHKsgX How a Molecular Motor Minimizes Energy Waste https://t.co/zOX3TAsljc

Thanks @FQXi for highlighting our work!
(Thread 1/3) Cells are noisy. And that noise may be useful. In "Maximizing power and velocity of an information engine," Bechhoefer’s team showed how a laser-trapped bead can bank energy from random jiggles, acting as an information engine with power on the scale of molecular

Kudos to Matt for his complete leadership from start to finish on this review, which was invited as a result of his compelling, cohesive, and ground-breaking graduate research!
Now out in @AnnualReviews of Physical Chemistry: @DavidASivak and I review recent work studying flows of free energy into, out of, and within molecular machines. These nanoscale protein machines convert energy within cells of all living organisms with remarkable efficiencies.

Great to see external recognition for what I experience everyday @SFU_Science: bad-a*% researcher, pioneering teacher, and tireless service as both leader and supportive colleague. (I also commend @ApsDbio for their sage decision to bask in her reflected glory.)
