# Robert Hickingbotham

# Hi There!

I am a PhD student in the Discrete Mathematics Research Group at Monash University. My supervisor is David R. Wood. I received my undergraduate degree at Monash University where I completed my Honour's project in structural graph theory with the same supervisor. I was the recipient of Monash's 2019 Pure Mathematics Prize for being the most outstanding Honour's student in pure mathematics. I co-organise the seminars for the Monash Discrete Maths Research Group. Details for upcoming talks can be viewed here.

**Research Interests**

Structural Graph Theory

Linear Layouts of Graphs
