Andreas Kafizas is a Junior Research Fellow at Imperial College London. He has experience in the fields of solar fuels generation, heterogeneous photocatalysis and functional window coatings (such as intelligent thermochromic and self-cleaning windows). He has extensive experience growing a wide range of materials using chemical vapour deposition (CVD) processes. He has also developed novel methodologies for the high throughput optimisation of material function using combinatorial CVD strategies. With expertise in transient absorption spectroscopy (TAS), he has been able to link charge carrier behaviour with photocatalytic activity for solar fuels generation.

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 the Junior Research Fellowship at Imperial College London. During his research career, he has published over 50 peer-reviewed papers, written 3 book chapters and amassed over 1400 citations, reaching an h-index of 25.
