From Aug 2021- Jul 2025 I was Head of the Department of Biological Sciences. I am currently on sabbatical leave until the summer of 2026. 

As a teaching-focused academic, much of my time is spent in teaching undergraduates. I use innovative teaching methods and publish in the pedagogical literature, as well as in my discipline. My main teaching responsibility in the School of Biological Sciences is running the large 1^st year biological chemistry modules (BS1031 and BS1032). I design and teach the whole of these modules, which include a large practical component. As well as giving traditional lectures I use Pearson’s Learning Catalytics to run in-class problem-solving sessions, which improve engagement and feedback, and I deliver course content online in a blended, semi-flipped approach. I have won several Royal Holloway awards for my teaching in this course, most recently a College Excellence Teaching Commendation in 2020.

I also supervise 3^rd-year undergraduate research projects (Independent Research Project, BS3010). Some of these projects are in the areas described below, while others are in different fields, such as smartphone spectrometry, the biological uses of nanoparticles, and environmental chemistry.

Bacterial biofilms

I am interested in the growth of bacteria on surfaces, particularly in the context of biofilm-focused infections. Along with Dr Shobana Dissanayeke (RHUL), Dr Arshad Khaleel (St Peter’s Hospital, Chertsey) and various Masters students we are investigating biofilm growth and antibiotic resistance on different orthopaedic materials, with a view to reducing clinical infection rates.

Elli Amanatidou’s PhD project on antibiotic resistance in E. coli biofilms, funded by the Charles Sykes Trust and run in collaboration with Dr Ben Raymond, used a combination of microbiological, chemical and evolutionary ecology techniques to analyze the interaction of antibiotics with in vivo biofilms. We are particularly interested in the social aspects of resistance, e.g. the extent to which β-lactamase-producing cells can protect neighbouring cells within a biofilm.

Biological electrochemistry

We use electrochemical methods to probe biologically important redox reactions. Chronocoulometry may be used to measure the concentrations of redox-active antibiotics, for instance, and we use cyclic voltammetry to investigate the interactions between model membranes and the mitochondrial protein cytochrome c. In collaboration with Prof Surendra Mahapatro we are investigating the redox chemistry of substituted aryldiazonium salts, which have important uses in chemical biology.

Pedagogy

I am interested in active learning techniques in the biosciences, the use of technology in teaching and the development of novel teaching laboratory activities in biological chemistry. As well as publishing in these areas I regularly present my work on these topics, both within Royal Holloway and at national meetings. In the 2022-23 academic year I co-led the PEMENTOS peer-mentoring scheme for undergraduates in the School of Life Sciences and the Environment.
