About Anna Reynal Verdu

My academic career started by studying a BSc in Chemistry at the University of Girona (Spain). I then moved to the University Rovira I Virgili (Spain) to study a MSc in Nanoscience and Nanotechnology.

During this time, I developed an interest towards renewable energies, and in 2006 I joined the research group of Dr. Emilio Palomares as a PhD student, in the Institute of Chemical Research of Catalonia (ICIQ, Spain). My thesis focused on the development and characterisation of molecular-based nanostructured devices for photovoltaic applications.

After completion of my PhD in 2010, I moved to Imperial College London (UK), to work as a Postdoctoral Research Associate in Prof. James Durrant's group. My research focused on the study of molecular and nanostructured solar-to-fuel conversion systems using advanced time-resolved spectroscopic techniques. I was awarded with a Marie Curie Career Integration Grant (CIG, 2012) and a Postdoctoral fellowship from the Spanish Government (2011). During this time, I obtained a Certificate in Supporting Learning and Teaching from Imperial College London.

My academic career continued as a Teaching Fellow at Newcastle University (UK), between 2015-2016. I delivered lectures in Inorganic and Physical Chemistry to 130 undergraduate students, and I was a senior laboratory demonstrator and tutor. I also obtained a Certificate in Learning, Teaching and Engaging Students and became an Associate Member of the Higher Education Academy.

In 2016, I became a Senior Lecturer in Inorganic Chemistry at Teesside University (UK).

In addition to my academic achievements, I think it is very important to disseminate my research to the general public. Since 2009, I have organised 7 summer schools for secondary school students, under the prestigious Spanish program "Youth and Science". I have also organised events at the Science Museum Lates (London, UK), the Big Bang Fair (London) and theGreat North Museum (Newcastle, UK).

Research interests and activities

My research interests lie in the field of solar energy conversion and storage. I have expertise in the development and characterisation of dye sensitised systems for solar cells and solar fuels. In particular, I have studied hybrid systems, composed of a nanostructured semiconductor functionalised with molecular dyes and catalysts.

My unique expertise is the study of electron transfer kinetics and reaction mechanisms using time-resolved spectroscopic techniques, such as transient absorption spectroscopy and time correlated-single photon counting.

I am interested in correlating the performance of photocatalytic systems to the molecular structure of the dyes and catalysts employed. Thus, my work aims to establish rules to control the electron transfer kinetics and mechanisms that are critical for the solar-to-fuel conversion.
