Andreas Kafizas is a Lecturer in Climate Change and the Environment at the Grantham Institute, Imperial College London. His research is focused on developing light-activated coatings that can drive useful chemistry using sunlight (e.g. coatings for building façades that can purify polluted city air). For these coatings to be commercially viable and sustainable, they are produced using low-cost, upscalable methods (e.g. chemical vapour deposition) using earth abundant, non-toxic materials (e.g. metal oxides).

Andreas is interested in developing new light-activated materials, and combinations thereof, to improve the function of these coatings. His core interests are to developing light-activated materials for renewable fuels production (e.g. hydrogen fuel from water and carbon-based fuels from CO2), air remediation (NOx removal) and water remediation (arsenic removal). Andreas also have experience developing coatings for thermochromic and electrochromic windows. He also has a keen interest in combinatorial materials discovery, and has developed novel high throughput strategies for optimising functional materials. Moreover, Andreas has studied the excited states formed in these light-activated materials using cutting-edge time resolved spectroscopies, and has been able to link their behaviour with activity and reaction mechanisms.

Andreas Kafizas completed his MSci in Chemistry at University College London in 2007, where he remained to undertake his PhD under the supervision of Prof. Ivan Parkin. Upon completing his PhD in 2011, he was awarded the Ramsay Medal for best graduating doctor in the Department of Chemistry. In 2012, he was awarded the Ramsay Fellowship, where he studied under Prof. James Durrant at Imperial College London. In 2016, he was awarded a Junior Research Fellowship, Imperial College London. In 2018, he was awarded a Lectureship at the Grantham Institute, Imperial College London.

During his research career, he has published over 60 peer-reviewed papers, written 4 book chapters (1800 citations, h-index 28).

Andreas is actively involved in showcasing his research to the public, recently taking part in Pint of Science, the Imperial College Festival and Outreach in schools.
