My intellectual home base since 2000 is the Department of Physics at the University of Toronto (UofT). I am also cross-appointed status-only in the Department of Mathematics. UofT has a college system, and I am a Fellow of Trinity College.

The Perimeter Institute for Theoretical Physics in Waterloo, Canada, has counted me as an Affiliate since it was launched. By choice, I am a member of the Canadian Association of Physicists (CAP), the [Canadian] Institute for Particle Physics (IPP), and the American Physical Society (APS). Like my Ph.D. advisor, I do not seek membership in highly exclusive clubs like the Royal Society, for the same reason as Groucho Marx gave 70 years ago.

My research is in the general field of theoretical subatomic physics. My specific expertise is centred on the following topics:-

- String theory as a theory of quantum gravity. Quantum field theory. Applications of string theory to black holes, gauge theories, and cosmology. Holographic AdS/CFT dualities between quantum gravity in asymptotically Anti de Sitter spacetimes and large-N quantum field theories with conformal symmetry.
- Microscopic modelling of quantum black hole physics using string theory. Mechanisms for resolution of the black hole information paradox.
- Conformal field theory descriptions of quantum gravity. Holographic connections between emergence of spacetime geometry and quantum information theory.

All of my research preprints and papers have been available for free from arxiv.org and inspirehep.net since the day they were born. Here is a selection, strongly biased towards recent work.

Ever since I was a graduate student, I have really enjoyed classroom teaching and mentoring students formally and informally. Over the years, I have taught a wide variety of classes, from elementary first year undergraduate courses to advanced graduate courses. 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.

For the academic year 2018-19, I am teaching

- PMU199S Modern Physics for the Curious
- PHY483F/1483F Relativity Theory I
- PHY484S/1484S Relativity Theory II

Bringing an appreciation of academic research to a wider audience is another academic activity I value a great deal. In the past quarter century, I have given engaging talks about theoretical physics to audiences from third graders to ninety-plus year olds. I list myself in the UofT Blue Book of experts, and provide online archives of outreach talks for the lay public. See e.g. the slides and YouTube video for my most recent public lecture.

I also keep a list of news media interviews. My motivation to reach out is not just to boost my research, my field, and physics more generally, but also to exercise an academic obligation enshrined in the Education Act (1989) of my home country New Zealand: to be critic and conscience of society

Since arriving at the University of Toronto, I have been involved in fostering inclusion of women in physics, at the departmental, university, national, and international level. From 2011-2014, I served on the APS Committee on the Status of Women in Physics (CSWP). From 2017-18, I chaired the CAP Committee to Encourage Women In Physics (CEWIP), and I currently serve on the CAP EDI Committee. Since acquiring disabilities in 2003 pre-tenure, I have been involved in fostering inclusion of disabled university students and researchers (see e.g. a 2012 Editorial I wrote for the APS CSWP/COM Gazette). Since coming out as transgender in 2013, I have been involved in fostering inclusion of gender and sexual minorities on campus. I list myself on lgbtphysicists.org Out List and have spoken on a number of LGBTIQ+ panels on campus and at physics conferences. Currently I also chair our departmental Inclusivity Committee. My overall sense is that like any other workplace, universities do not have to choose between building excellence and building inclusiveness. It is entirely possible to do both, and we must, because the future health of the academic profession depends on it.
