Sarah Horswell is a lecturer in Physical Chemistry. She has a range of research interests in the field of Surface Electrochemistry, ranging from biomimetic films to electrocatalysis. Her work has been funded by EPSRC and the EU and she is involved in several national and international collaborations.
PhD in Chemistry, University of Liverpool, 2000
MSc in Surface Science and Heterogeneous Catalysis, University of Liverpool, 1995
BA in Chemistry, Cambridge University 1994
Sarah Horswell qualified with a BA (Hons) in Chemistry from Cambridge University in 1994. She obtained an MSc in Surface Science and Heterogeneous Catalysis from the University of Liverpool in 1995 and stayed there to study for PhD in Electrochemistry of Nanostructured Systems. She then spent 15 months at the University of Guelph, Canada, where she worked in the area of interfacial electrochemistry and in situ spectroscopy. This was followed by a period of 3.5 years at the Fritz Haber Institute in Berlin, Germany, where she worked on electrochemical surface science and catalysis. She took up a position as Lecturer at Birmingham in 2004.
She teaches Physical Chemistry to students in Years 1-4 and is actively involved in teaching development activities. She leads a research group specialising in electrochemical surface science: ranging from biomimetic systems to nanostructures and surface-catalysed reaction
PhD and (formerly) MRes project supervision in the areas of solid-supported biomimetic membranes and electrocatalysis
The focus of our research is the application of in situ optical techniques, particularly infrared spectroscopy, to study adsorption processes and reactions at metal electrode surfaces. Of current interest is the effect of the electric field on the conformation adopted by phospholipid bilayers assembled on electrode surfaces and their interaction with peptides.
Our interests also include modification of surfaces with organic molecules and/or metal nanoparticles, and electrocatalysis. Classical electrochemical methodology is combined with modern in situ techniques to determine structure of our tailored surfaces and catalysts as well as reaction mechanisms. The underlying theme of our work is to understand interfacial processes at a fundamental level, with a view toward exploiting this information in the development of new materials, sensors or catalysts
