Postdoc & Lecturer

University of Oxford & Wadham College

I am a CBET/EPSRC-funded postdoctoral research assistant in fluid dynamics at the Department of Engineering Science of the University of Oxford, working with Alfonso A. Castrejón-Pita in the Fluid Dynamics Laboratory. I am concurrently a lecturer in engineering at Wadham College, Oxford, teaching undergraduate engineers mathematics, thermofluids, and computer-related electrical engineering. Previously, I completed an undergraduate Mathematics degree (BSc, Leeds, 2016) and an integrated PhD/MSc in the EPSRC Centre for Doctoral Training/ Leeds Institute for Fluid Dynamics (LIFD) at the University of Leeds in 2020.

My research interests lie in fluid dynamics, especially of droplets, interfaces and complex fluids. I adopt a highly-interdisciplinary and collaborative approach to research, utilising a range of techniques including numerical simulations, laboratory (usually high-speed imaging) experiments and mathematical modelling, often in combination. Specific application areas of interest include microfluidics, inkjet and biomaterial printing, additive manufacture, aerosols (especially generation), infectious disease transmission (airborne and droplet), molecular communication and environmentally-friendly crop sprays.

Please feel free to contact me about any aspect of my work.
