Biography

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).

Prof Walker has 40 years postdoctoral research experience in microbiology and biotechnology. He is director of the Abertay Yeast Research Group which investigates aspects of growth, metabolism and stress in yeasts of industrial, environmental and medical significance. Research funding for this 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) and professional bodies (e.g. Institute of Brewing & Distilling). He has previously supervised 19 PhD, 30 research Masters, 110 BSc Honours and 16 visiting Erasmus research students to successful completion. Collaborative research projects have been undertaken with several academic and industrial partners in the UK and internationally. Current (PhD) projects include:

- Investigating yeast biodiversity for whisky fermentations

- Evaluating legumes for brewing and distilling

- Immobilised non-Saccharomyces yeasts for wine fermentations

- Bioethanol from marine biomass

- Wood maturation of distilled spirits
