Post-Graduate Students

Paul Ryan
I graduated from the University of Bristol with an MSci in chemistry in June of 2016. I joined Dr Payne’s group at the beginning of 2017 to start a project investigating metal/ metal-oxide support interfaces and their effects and importance for heterogeneous catalysis, with a specific focus on iron oxide supports. I will be utilising ambient pressure and diffractional photoelectron techniques throughout the project and will be situated at both Imperial and Diamond light source in Harwell. During my final year at Bristol, I undertook a project formulating Pickering stabilised water-in-water emulsions and investigated the effect that polymers, adsorbed to the stabilising particles’ surface, have on the final emulsion.

Enrico Manfredi-Haylock.
I’m starting my PhD in Dr. Payne’s group looking into the chemical and electrochemical recycling of lead acid batteries. My specific interest is in developing a rationalised design strategy for the new class of “Deep Eutectic Solvent” systems that are being explored to efficiently dissolve lead compounds based on ab-initio and machine learning methods. I will then move on to using this design process to select an optimal solvent to prepare a full engineering demonstration rig at the end of my doctorate.

Vincent Chung
To be completed very soon.


Xiaoru Li
I graduated from Harbin Institute of Technology in Materials Science and Engineering with a bachelor’s degree and completed MEng at the University of Manchester in June of 2018. Then I joined Dr. Payne’s group as a PhD to study the basic mechanisms of metallic nanoparticles such as silver and gold. Novel behaviours have been observed in-situ via a high-resolution transmission electron microscope. I am trying to principally understand the adhesion and deformation of particles at the interface and simulate the realignment process.


Yanying Wang
I graduated from Loughborough University with an MSc in Materials in September of 2018. I then started my PhD in Payne’s group looking for green methods to reduce the environmental impact of lead. The research includes lead acid battery recycling and lead contaminated water purification. I will try to find an optimal solvent and prototype to offer the possibility for industrial application.


Syuhada Binti Mohd Tahir
I joined this research group in April 2019 as PhD candidate, co-jointly supervised Dr David Payne and Prof Martin Heeney. My interest is on work function modification of conjugated polymer electrolyte (CPE) as promising interfacial layer materials in organic energy devices. The effect of varying ionic density in CPE on the work function modification will be studied using X-ray photoelectron spectroscopy in order to understand the underlying mechanism that cause the electronic level rearrangement. Previously, I graduated with MSc in Chemistry from National University of Malaysia in 2010 and have been working with MARA University of Technology, Malaysia, since 2011.


Alexis Belessiotis (Lead supervisor: Professor Molly Stevens, Imperial College London)
I graduated from Imperial College with an MEng in Materials Science & Engineering in June of 2016. I then joined the Advanced Characterization of Materials Centre for Doctoral Training (ACM CDT) for a PhD working jointly with Prof. Molly Stevens, Dr David Payne at Imperial and Prof. Giuseppe Battaglia at UCL. My project focuses on the fabrication and characterization of porous Silicon nanoneedles for use in direct cellular manipulation. These needles are highly efficient in delivering drugs into cells and my goal is to understand the basic science behind the biointerface between the cell membrane and this inorganic material.
