Dr Xiaochu Wei

Hi, I am a Research Associate working with Dr Anna Hankin and Professor Magda Titirici. I completed my PhD in 2022, supervised by Dr Anna Hankin and Professor Geoff Kelsall in Chemical Engineering Department at Imperial College London where I also obtained an MSc in Advanced Chemical Engineering in 2017. My research focuses on the development of new processes to recover critical metals from multi-chemistry, end-of-life Li-ion and Na-ion batteries.  

Dr John Rodriguez Acosta

Hello, I am working on up-scaling solar hydrogen production. I am modelling, designing, fabricating and testing novel prototype photoelectrochemical (PEC) systems. I received my Bachelor’s and PhD degrees at University of Valley, Colombia.

Visiting Researchers

Arend Moelich

Hello, I’m Arend! I’m a master’s candidate at Stellenbosch University (SU), South Africa, collaborating with Imperial College London on Solar2H2. My research is on the development of a concentrating solar optics system for photoelectrochemical hydrogen production. My background in mechanical engineering (BEng (Mechanical) at Stellenbosch University), and my love for nature, has led me to my current role as a researcher in the renewable energy field.
