Fiach specialises in physical chemistrry and the simulation of microfluidic and electrohydrodynamic systems.

​Fiach studied both Molecular Biology and Electrical & Computer Systems Engineering at the University of Queensland. During his undergraduate degree, he published in the field of Wireless Sensor Networks alongside the CSIRO, and joined the Australian Institute of Bioengineering and Nanotechnolgy as a summer research intern where he developed tools for the analysis of nanopore-based Resistive Pulse Sensing data. Once he completed his Bachelors of Science and Bachelors of Engineering/Masters of Engineering degrees, he joined the Trau group as a PhD student researching nanopore systems for nanoparticle trapping and single-particle characterisation. Now he works as a post-doctoral researcher for the Trau group on a number of projects, covering all aspects of physical chemistry and computational simulations/data analysis.
