MIT

As a Physics of Living Systems Fellow I have been working with Arup Chakraborty and Jeremy England's groups. I am broadly interested in studying fluctuations in high-dimensional dynamical processes. See, for example, my recent papers, "Dissipation bounds all steady-state current fluctuations" and "Inferring dissipation from current fluctuations"

Berkeley

I completed my Ph.D. under the supervision of Prof. Phill Geissler, studying path sampling methods for systems driven out of equilibrium, large deviations in dynamical processes, and pattern formation.

  • Phill and I analyzed path sampling inefficiencies, and showed that in a special case of Ising model dynamics an efficient sampling algorithm can be constructed.
  • Grant Rotskoff, Suri Vaikuntanathan, and I used large deviation theory to investigate efficiency distributions in stochastic heat engines.
  • Suri, Phill, and I investigated a dynamic phase transition in simple non-equilibrium kinetic networks.

Oxford

At Oxford I worked with Dr Mark Wilson to study inorganic nanotube formation within simple models of carbon nanotubes. It has been observed that some beautifully geometric (and potentially technologically useful) salt structures can form within carbon nanotubes. It appears through some experiments, but largely through theoretical calculations, that a significantly greater variety of crystal structures could be expected to form as compared to bulk crystals. With unique structures tends to come unique physical properties, properties which may well be of technological use. Our work aimed to make better sense out of the factors influencing the formation of these intercalated crystal structures, albeit within a simpler, computationally feasible model of the system.

My Castle In the everyday macroscopic world construction is simple enough, for we can pick things up and move them around as we see fit. In contrast, when attempting to position atoms in the right manner it requires either laborious and expensive methods, for example laser tweezing, or it requires a self-assembly process whereby the atoms independently "want" to go to the right position. It is not straightforward to determine how these desires of the atom to organize are influenced by macroscopic factors that we can simply control (temperature, pressure, voltage bias on the carbon nanotube, etc.) We worked with basic classical models of metals to probe these complex interactions through computer simulation

Caltech

Metal Oxides I entered Caltech in the fall of 2004 and graduated in 2008, earning a B.S. in Chemistry with honors. While at Caltech, I briefly worked in the lab of Prof. Harry Gray studying protein folding. I later spent two years researching mixed metal oxides in the group of Prof. Nate Lewis. In my final summer after graduating and before moving away, I worked under Prof. Tom Miller studying computational protein dynamics of the Sec channel. More information about my time at Caltech can be found on my old Caltech webpage. A list of my courses is here.
