Dr Oliver Janzer received his PhD in 2020, after completing his undergraduate and postgraduate studies at Trinity. He has since been a postdoctoral researcher at ETH Zürich and a Junior Research Fellow at Trinity. His research focuses on Discrete Mathematics, more specifically Graph Theory.

Graphs are mathematical objects that can be used to describe networks such as Facebook. In this talk, Oliver will give a gentle introduction to Graph Theory and discuss one of the most central problems in the field.
