I am Zoe Wyatt, a Herchel Smith Postdoctoral Research Fellow at the Department of Pure Mathematics and Mathematical Statistics and a Junior Research Fellow at Darwin College, University of Cambridge.

My research lies at the intersection of general relativity, differential geometry and hyperbolic PDEs. I am very interested in studying PDEs derived from theories of higher dimensional gravity, string theory, particle physics and cosmology. My contact details are firstname.surname@maths.cam.ac.uk.

- I helped run a Maths Circle teacher training session for 35 teachers, plus the Maths Circle in the afternoon (235 parents and kids!), on February 29.
- I helped organise and/or present at two Virtual Maths Circles on August 5 (over 100+ participants) and on October 3 (over 150+ participants)
- I gave a talk about “Life as a PhD student” to a group of 30 female undergraduates for the Piscopia Initiative which aims to promote female students doing PhDs.

In Edinburgh in 2019:

- I helped run Maths Circle teacher training sessions for about 45 teachers on both March 2 and December 14, as well as assist at the Maths Circles on March 2, October 12 and December 14.
- I co-wrote a successful small grant proposal (£1450) for Widening Participation in the Maths Circles awarded by the Edinburgh University’s Principal’s Teaching Award Scheme (PTAS).
- I was a helper at one of the Royal Institution Mathematics Masterclass events on May 18.

- This is a picture of me doing a stand-up comedy routine about the electroweak theory of particle physics at the Glasgow Bright Club, as part of Glasgow Science Week. I also performed the same routine at the 49th Edinburgh Bright Club. You can watch the videos here and here!
- We successfully received another grant from the Glasgow Mathematical Journal Trust that will support the Maths Circle for the next 4 years
- I helped at a small Maths Circle event on October 5 as part of Maths Week Scotland, to reach out to different communities in Edinburgh.

In Edinburgh in 2018:

- We received a
*£*500 grant from the Edinburgh City Council to develop our Maths Circle resources to loan out to schools and I have been significantly involved in producing these resources. - I was awarded the Sir William Darling Memorial Prize (and an award of £1000) by Edinburgh University for my maths outreach work in founding the Edinburgh Maths Circle. The prize recognises “such student who has done in any year most to advance or enhance the reputation [through conduct, example, scholarship or pre-eminence in sport] of the University”.

In Edinburgh in 2017:

- I wrote an interactive problem and a poster explaining the maths (and relativity) behind GPS for the Edinburgh International Science Festival.
- I wrote a problem about different types of map projections for a Maths Escape Room, for the Edinburgh University Innovative Learning Week.

- We were awarded a
*£*1200 grant from the Glasgow Mathematical Journal Trust to keep running the Maths Circles.

- This is a picture of me giving a stand-up comedy performance about Black Holes at the 43rd Edinburgh Bright Club, held at the Stand comedy club in Edinburgh, see the video here!
- My former college Newnham has a Wall of Women page where I appear talking about AIMS.

In Edinburgh in 2016:

- Inspired by a similar event in Cambridge, I started the Edinburgh Maths Circle which has been very successful (averaging 200 attendees at each Circle).
- I helped organise, write problems for and run three of these Maths Circles on 28th May, 10th September and 3rd December.
- I made a poster about the physics behind building cathedrals for the Edinburgh International Science Festival.

In South Africa from 2014-2015:

- I was a tutor at AIMS South Africa for 1 year, teaching and mentoring around 60 underprivileged students from 19 African countries, as they completed their Masters program. Here is a picture of me and some of my incredible students on graduation day.

- Writing CVs and Statements, 4 page PDF which I wrote for AIMS students, but could be applicable for others.
- I gave a talk at my former high-school about what a degree in maths can do for you.

In undergrad at Cambridge:

- I helped at Cambridge Maths Circle events (2010-14).
- I did a summer internship (2011) at NRICH, writing problems and other mathematics material.
- In my second year (2012) I co-founded with Anna Seigal the Emmy Noether Society for female mathematicians at Cambridge University.
- I helped organise many events for the Emmy Noether Society.
- I appeared in a PDF about Former Students given to new Cambridge maths students.
- I taught a small group of 9/10-year-old students for a lunchtime Maths Club (2013).
- I made a poster (2014) about famous female mathematicians and another poster about the Emmy Noether Society for an open day at Cambridge University.
- I organised a Wikipedia Women in Maths Editathon (2014) at Cambridge to improve Wikipedia articles about female mathematicians.

In my spare time I love birds, bird-watching, my cat Amber, reading and cycling.
