My intellectual home base since 2000 is the Department of Physics at the University of Toronto. I am also cross-appointed (status-only) in the Department of Mathematics.

The Perimeter Institute for Theoretical Physics in Waterloo, Canada, has counted me as an Affiliate since it began. By choice, I am a member of the Canadian Association of Physicists, the [Canadian] Institute for Particle Physics, and the American Physical Society.

My interests are centred around the following topics:-

- String theory as a theory of quantum gravity; quantum field theory.
- Applications of fundamental string theory to black holes, gauge theories, and cosmology.
- Microscopic modelling of black holes/branes using string theory methods.
- Conformal field theory (CFT) descriptions of quantum gravity.
- Mechanisms for resolution of the black hole information paradox (fuzzballs, firewalls,
ER=EPR

wormholes etc.). - Connections between emergence of spacetime geometry and quantum information theory.
- Holographic AdS/CFT dualities between large-N gauge field theories and gravitational string theories.
- Gravitational explorations in holography applied to modelling aspects of strongly coupled condensed matter systems.

I enjoy classroom teaching, including making connections between lecture material and research frontiers. I am committed to open access and to accommodating students with disabilities, so my courses all feature online lecture notes, and have done since I started teaching at UofT in 2000-1. Mentoring/teaching of research personnel is also a high priority. I am always on the lookout for tips for better teaching.

For the academic year 2017-18, I will be teaching

- PMU199S
*Modern Physics for the Curious* - PHY483F/1483F
*Relativity Theory I* - PHY2404S
*Quantum Field Theory II*

Our Department of Physics is strongly committed to fostering an equitable and excellent atmosphere for everyone. Since arriving at the University of Toronto, I have been involved in gender equity efforts at the departmental, university, national and international level (e.g. I served on the APS Committee on the Status of Women in Physics for 2011-14). More recently, I have also developed an interest in equity for people with disabilities (see e.g. a 2012 Editorial I wrote for the APS CSWP/COM *Gazette*) and for gender and sexual minorities. I support the UofT Positive Space Campaign and list myself on lgbtphysicists.org Out List. Currently I also chair our departmental Diversity Committee. Inclusiveness-building alongside excellence-building is a smart strategy for any workplace, and universities are no exception.

I work to bring an appreciation of my research to a wider audience. I list myself in the UofT Blue Book of experts, and provide online archives of technical talks for researchers and outreach talks for the lay public. See e.g. slides and YouTube video for my most recent public lecture. I also keep a list of news media interviews.
