Biography

Biography

I graduated from the Department of Mechanical and Aerospace Engineering at the University of Strathclyde with a 1st class BEng (Hons) degree in 2009, before starting a PhD in the same department soon after. At the end of my first year I was awarded a prestigious James Weir Postgraduate Scholarship, I was the recipient of an IMechE Thomas Andrew Common Travel Grant in 2010, and participated in a one month academic visit to the Center for Computational Sciences and Engineering at the Lawrence Berkeley National Laboratory. My doctoral work led to numerous publications covering microscale flows, hypersonics, and orbital dynamics. My thesis was entitled "Benchmarking, Development and Applications of an Open Source DSMC Solver" and was completed in early 2013.

After my PhD, I began a post doctoral research associate position, also at the University of Strathclyde, working on the EU ABLAMOD FP7 collaboration. This program aimed to increase the understanding and improve the modelling of ablative materials for use in the next generation of atmospheric re-entry heat shield technologies, and involved working with academic and industrial partners from across Europe.

I joined the Aerospace Sciences Division at the University of Glasgow as a lecturer in December 2014.

Research interests

Research Interests

My research interests are in fluid dynamics, primarily the simulation of gas flows using the direct simulation Monte Carlo method and experimental work with vacuum chambers. A key area of my work has been modifying and extending the free and open source dsmcFoam code. In addition, I am interested in continuum CFD and machine learning techniques.

Expertise

I am involved in delivering CPD training courses on the dsmcFoam code, that are normally held in April each year.
