I am a Senior Lecturer in Mechanical Engineering at the University of Edinburgh. I am a computational engineering scientist exploring nanoscale interfacial phenomena using simulation, with a particular focus on phase change, droplet dynamics, and heat transfer at solid–liquid interfaces.  My research combines molecular dynamics (including machine-learning interatomic potentials) with continuum modelling and multiscale coupling methods to connect atomistic physics to engineering-scale behaviour. A recurring theme is understanding how nanoscale mechanisms govern macroscopic outcomes: how droplets move (and sometimes jump), how surfaces clean themselves, how ice nucleates, and how heat is transported across interfaces.  

I lead an £1.3M UKRI/ERC-funded research grant (NANO-COOL) investigating nanoscale mechanisms of phase change and their implications for thermal control, and I am a group leader within the multiscale flow (mfX) research group (with Duncan and Livio), where we develop multiscale methods and high-performance computing software for complex flow and transport problems.

I am actively involved in academic service and research leadership within the School and the wider University. I currently serve as Postdoctoral Researcher (PDRA) Champion for the School of Engineering, a role focused on improving postdoctoral support, career development, and research culture. In this capacity, I have contributed to the design and implementation of postdoctoral induction and professional development initiatives aligned with the Concordat to Support the Career Development of Researchers.

Gary's research focuses on the applications of surface coatings, and he designs and builds experiments and instrumentation to produce and understand the adhesion and friction of droplets on surfaces. He has conducted experimental research into surface coatings and their various applications. The coatings he has developed can be used in many applications, including heat and mass transfer and anti-fouling. 

As part of the WISE group, Gary collaborates with theoreticians to develop instrumentation and experiments to test and understand solid-liquid interfaces. His experimental research has led to multiple publications in high-ranking journals, with over 50 peer-reviewed articles in journals such as Langmuir, Nature Communications, Soft Matter, and the Journal of Fluid Mechanics.

We invite applications for a PhD position to advance flue gas cleaning technologies from industrial emissions, particularly in Energy-from-Waste (EfW) power plants. The EfW solutions incorporate advanced flue gas cleaning systems that notably reduce landfill waste, lower emissions, generate energy, and assist in material recovery, thus supporting a sustainable closed-loop circular economy. The appointed researcher will contribute to the EPSRC funded M2CLEAN project, which intends to thoroughly investigate the complex dynamics of particle interactions at various scales, including those between solid particles, liquid droplets, and gas phases. The research work will tackle key operational challenges such as regulating temperature and humidity, alongside optimising particle size and distribution to increase emission removal efficiency. The primary goal of this project is to create experimentally informed predictive models that detail these inter-particle interactions, enhancing understanding and efficiency of semi-dry flue gas cleaning systems.

The current Ph.D. position focuses on the experimental investigation of particle-droplet interactions under acoustic levitation. The project aims to foster a new understanding of the spatiotemporal scales and the controlling parameters of particles when subjected to varying temperature and humidity. The project offers hands-on experience in setting up multiphase experiments and using several state-of-the-art optical diagnostics, such as high-speed shadowgraphy, Particle Image Velocimetry (PIV), and Planar-Induced Fluorescence (PLIF).

The ideal candidate will be interested in fluid dynamics, reacting flows, and laser diagnostics and have programming experience in at least one language (e.g., Python, MATLAB, etc.). The selection process considers the comprehensive strength of the entire application, including the academic qualifications, personal statement, CV, and references. Ideally, candidates should have a strong background in fluid dynamics and the development of experimental methodologies.

The project includes close collaboration with TU Darmstadt, Germany and industrial partner Kanadevia INOVA, Zurich, Switzerland. This collaborative environment will offer the opportunity to learn from and contribute to a diverse team of experts. 

The intended PhD start date is in beginning of April 2026. If a suitable candidate is found, this position may close earlier than the closing date. 

Informal inquiries may be addressed to Dr Khushboo Pandey at kpandey@ed.ac.uk.

Minimum entry qualification - an Honours degree at 2:1 or above (or International equivalent) in a relevant science or engineering discipline. The candidate should have a master’s degree in either Physics or Engineering.
