My name is Belgin Seymenoğlu. I am reaching the end of my PhD in Mathematics at UCL, which is also where I gained my MSci in Mathematics with Mathematical Physics. Moreover, I have recently started teaching at the University of West London. Welcome to my academic webpage!

Many models in population genetics feature some form of convergence of the genetic state of the population, typically onto a so-called invariant manifold. This allows one to effectively reduce the the dynamical system to a problem with fewer dimensions, making it easier to investigate the stability of the fixed points in the model, as well as to predict the long-term evolution of the population.

In some models, an invariant manifold is known to exist, but with some very restrictive assumptions such as weak selection or additive fitnesses. My aim was to prove the existence of an invariant manifold for a handful of models in population genetics without relying on such assumptions, hence my results will be much more widely applicable.

I submitted my thesis this September, and had my (five-hour!) viva this month. My examiners were Rod Halburd and Josef Hofbauer. I am also turning parts of my thesis into papers.

Also, I gave a talk about my research in the Applied Mathematics Seminar at UCL this autumn! You can find the slides for the seminar here.

I investigated Cosserat models of elasticity for my MSci project. Unlike classical elastic models, which neglect the local structure of points in an elastic body, Cosserat models take into account both the change in position of points and the so-called microstructure, in which said points are allowed to undergo rigid rotations. In my project I analysed coupled elastic and rotational waves in the Cosserat model of Continuum mechanics and found some interacting soliton solutions. Moreover, I created the colourful animation below using Mathematica to visualise these waves. I have since written a paper about my project (see my list of publications).

Since then, I have started comparing my Cosserat model with Skyrme's model from particle physics. The first step will be to put together a translation from Skyrme to Cosserat!

My office is in Room M201 of the Kathleen Lonsdale Building (Tue-Thu). Instructions for finding this room are given here. This term, you can find me in the University of West London on Fridays, where I am lecturing two courses.

I am presently teaching the second-year level course **Real and Complex Analysis** for the year at the University of West London. Lecture material will be posted here very soon!

I am presently teaching the Foundation level course **Introduction to Statistics** at the University of West London. Lecture material will be posted here very soon!

In the years 2015-2017 I taught the undergraduate course **Mathematics for Engineers 1**. All the lecture material for the course can be found here:

Here is the complete set of lecture notes for the course.

I am a member of the team behind Chalkdust, a UK maths magazine for the mathematically curious.

This April the KLB had a re-opening ceremony, during which we demonstrated a pile of matchboxes that can learn how to play noughts and Crosses to David Attenborough and others. We even got him to take away three issues of our magazine!
