Personal profile

Personal profile

I’m a Professor of Zymology and Director of the Abertay Yeast Research Group.

My PhD (1978) was in Yeast Physiology and I have over 40 years of research experience in microbiology and biotechnology.  I also act as consultant for international biotechnology companies.

My current research interests involve yeast physiology and biotechnology, with a particular focus involving optimising fermentations for alcoholic beverages, distilled spirits and sustainable biofuels. 

I have held academic positions and conducted research in the UK, Denmark, New Zealand, Ireland, Canada and the US. 

To date, I have published over 200 articles and authored several textbooks, including Yeast Physiology & BiotechnologyBioethanol and The Alcohol Textbook.


Lecturing duties in Microbiology and Biotechnology: Prof Walker acts as Module tutor and co-deliverer of modules in BSc and MSc programmes, covering topics such as Yeast Biotechnology, Fermentation/Bioprocess Technology, Food Biotechnology, Industrial & Biomedical Biotechnology, and Renewable Energy Technologies. He also supervises Research Projects (BSc Hons, MSc, MProf and PhD).


Research funding for the Abertay Yeast Research Group has been forthcoming from research councils (e.g. BBSRC), European Commission (e.g. Framework 6 Programme), industry (e.g. BP Chemicals, Glaxo, Heineken, Diageo), charities (e.g. Carnegie Trust), professional bodies (e.g. Institute of Brewing & Distilling) and governmental organisations (e.g. Technology Strategy Board, Industrial Biotechnology Innovation Centre).
