 Who am I? 
My face.
I am Matthew Scroggs. I like maths.
I have a Master's degree in mathematics from Oxford University. I am currently studying for a PhD in maths at UCL, where I work on finite element methods and boundary element methods. As part of my PhD work, I develop the open source boundary element method library Bempp. Between Oxford and UCL, I worked as a maths teacher in a secondary school. You can find more about my work on the academic page.
You can regularly find me at London MathsJam (second last Tuesday of the month), the MathsJam Gathering (yearly) and EMF Camp (every two years). I write the crossnumber (as Humbug), puzzles and articles for Chalkdust Magazine. For more non-work related articles and talks, see the talks page.
