Pronouns: they/he
I am a Professor of Pure Mathematics and Head of the Geometry and Mathematical Physics Research Group at the University of Birmingham. My research is in algebraic geometry and mirror symmetry. My research group is supported by a UKRI Future Leaders Fellowship.
Travel plans:
I am spending Winter 2024 at the University of Minnesota. I am spending Spring 2024 at Institut Mathématiques de Jussieu - Paris Rive Gauche, Sorbonne Université, as an FMSP Invited Professor.

Diversity in Mathematics:
With Alex Bond, I am a co-chair of the LGBTQ+ STEM Project which runs the LGBTQ+ STEMinar, the largest event in the UK for researchers in STEM.
I am on the advisory board for the potential new Academy for the Mathematical Sciences in the UK. My participation is focussed on the equality, diversity and inclusion workstream in the creation of the new academy.
I am a member of the Women and Diversity in Mathematics committee for the London Mathematical Society. Please get in contact regarding this work if you are interested or have any questions about the LMS initiatives with respect to reducing the gender gap in mathematics or broader diversity issues.
Lastly, I am the Staff Advisor for the University of Birmingham's oSTEM (out in Science Technology Engineering and Mathematics) organisation, the longest continuously running oSTEM chapter in the UK. They are an inspiring group of students and have won multiple university awards. Their annual event STEM LGBTQ and You was on the Guardian's list of top ten places to celebrate LGBTQ+ History Month in 2023.
If you are looking for consultancy with someone doing LGBTQ+ inclusion in Higher Education since 2007 with an expertise in STEM, then you are more than welcome to inquire about my rates via email.
