# It from Qubit: Postdocs

### Henry Maxfield

Henry Maxfield is a postdoc at McGill University. Originally from the UK, he studied mathematics at Cambridge University for his undergraduate and master’s degrees before moving to Durham, where he received his Ph.D. in 2015, supervised by Veronika Hubeny. His research centers on understanding how and why calculations quantifying quantum information map to geometric problems in gravity. Much of his recent work focuses on gravity in three space-time dimensions, where many problems become more tractable.

### Douglas Stanford

Douglas Stanford is a postdoc at the Institute for Advanced Study, in Princeton, New Jersey. He received his Ph.D. from Stanford University under the supervision of Leonard Susskind. His recent work has focused on the quantum properties of black holes and on chaotic dynamics in systems with many degrees of freedom. With Maldacena and Shenker, he proved a bound on many-body chaos that is saturated by black holes.

### Beni Yoshida

Beni Yoshida is currently a five-year senior postdoctoral researcher at Perimeter Institute for Theoretical Physics. He received his Ph.D. in physics in 2012 from Massachusetts Institute of Technology under the supervision of Edward Farhi and Peter Shor. Afterward, he was awarded the David and Ellen Lee Postdoctoral Scholarship in Theoretical Physics at California Institute of Technology (2012–2015) working in John Preskill’s group.

His research is focused on applications of quantum information theory to problems of quantum many-body physics. In particular, he has used the techniques of quantum coding theory to find novel topological phases of matter and developed a framework of classifying fault-tolerant logical gates by using topological gauge theories. More recently, he has become interested in black hole physics, trying to expand his horizons further.
