In his talk, Mikael illuminates us in why and how he managed to count 266682 number of ways to tie a necktie knot and the “mathemagic” behind it. He will show us how abstract mathematics can be illustrated in our everyday life in a simple and entertaining way, hopefully encouraging you to see another side of mathematics and embrace your own inner mathematician.

Mikael is a postdoc soon-to-be professor specialised in applied algebraic topology. His research stretches from topological data analysis to enumerating novel types of necktie knots using formal language.
