Sid graduated from the University of Rochester, USA with a BS in Physics and a BA in Mathematics in 2006. He then moved to Princeton University where he received a PhD in theoretical physics in 2011. He then spent three years (2011-14) at the University of California, Berkeley, as a Simons Postdoctoral Fellow in physics, before establishing an independent research group at the University of California, Irvine, where he was an Assistant Professor from 2014-2017. Sid was appointed as an Associate Professor in Quantum Condensed Matter Theory and a Tutorial Fellow in Physics at Hertford College in 2017.

Sid currently tutors the second-year mathematical methods and quantum mechanics courses. He will begin to lecture in the 2018-19 academic year.

Sid is not currently giving any graduate lectures, but expects to lecture in the 2018-19 academic year.

Sid is a theoretical physicist, whose work focuses on on quantum mechanical systems of many particles that are strongly interacting, far from equilibrium, or both.

Systems of interacting particles can display a variety of emergent cooperative phenomena that cannot be understood from their microscopic details. Usually, the study of this type of "condensed matter" builds on two key principles, namely (i) that most situations can be understood by approximately treating the constituents (such as electrons, atoms, or molecules) as weakly interacting; and (ii) that the assumption of thermal equilibrium provides a powerful way to capture the properties of complex systems using simple statistical tools.

Sid is interested in what happens when quantum systems are so strongly interacting, or so dramatically disturbed from equilibrium, that these guiding principles break down. A new set of ideas is therefore required to fully understand the behavior of such systems, and to explore their properties. Besides their great fundamental interest, many of the new phenomena displayed in these extreme regimes could have many important applications — particularly if new theoretical insights allow them to be reproduced in more conventional situations. Insights into weakly-correlated, equilibrium systems fueled the technological revolution of the second half of the twentieth century; what new and unexpected benefits might we accrue from understanding their more complex cousins? The exciting possibilities range from low-power electronics to revolutionary new technologies such as quantum computers.
