Matthias Fresacher (he/him) is an emerging researcher whose work focuses on analysing properties of the diagram monoids. Currently a Doctor of Philosophy student at Western Sydney University under the supervision of Assoc. Prof. James East, Matthias is investigating how the diagrams and operations of the diagram monoids can be generalised and aims to establish new properties of the original diagram monoids as well as the newly established generalisations.
Completing his Master's and Bachelor's degree at the University of Adelaide and on exchange at the National University of Singapore with a published paper, Matthias strives to continue to build his academic presence by researching a growing array of problems in various areas of pure mathematics and related subjects. With a general research aim of collaborating across disciplines, Matthias looks forward to exploring new problems and collaborations in his post doctoral ambitions whilst also continuing to develop his teaching skills and experience.
Matthias has lectured at Western Sydney University where he currently is a tutor and he also is an Indigenous academic mentor at the University of Adelaide.
