Fluid mechanics
Fluid mechanics (and in particular highly nonlinear interfacial flows) is my main research area at present. I started working on small scale electrohydrodynamics as part of my M.Sc. degree in Imperial and have continued being active in this field ever since [f1, f2, f3, f5, f10]. Starting with the late stages of my Ph.D. I have dedicated more and more resources towards high-speed flows and drop impact in particular [f6, f7, f8, f14, f15, f17, f19, f20, f21], which led to fruitful collaborations as part of OCIAM in Oxford. Across all areas I have also nurtured my interests in mathematical modelling, asymptotic analysis and numerical solutions for differential equations [f4, f9, f11, f12, f16], with new research strands in topics such as control theory [f13, f18].

Computational acoustics
My first research experience consisted in mathematical modelling, numerical analysis and software engineering for HIFU (high-intensity focused ultrasound) therapies at Fraunhofer MeVis Bremen. Two full-time summer stints, as well as a part-time role within my final undergraduate year resulted in expertise in wave equations and a thesis on perfectly matched layer techniques. This knowledge has then been re-deployed and advanced for both acoustic and elastic waves in a collaboration with Prof. Matthias Heil and Anton Martinsson at the University of Manchester through a project supported by Thales Underwater Systems.

Industrial mathematics
This large-scale project was initiated following promising early progress at ESGI 93 Limerick. It resulted in a consultancy role facilitated by MACSI, as well as development of dedicated methodologies for port activity planning involving mathematical modelling, statistics and queueing theory:
