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.

Research Interests

  • Structural Graph Theory

  • Linear Layouts of Graphs

  • Graph Product Structure Theory

Teaching

I have worked for Monash University as a sessional teaching associate in the following units:

  • MTH1030 - Techniques for modelling

  • MAT1830 - Discrete Mathematics for Computer Science

  • MTH2021 - Linear Algebra with Applications

  • MTH3170 - Network Mathematics

Conferences

I co-organised the 2020 Australasian Graduate Symposium in Combinatorics.
