Contact Details


I am a Reader in Biology and Director of Taught Postgraduate Studies in the Institute of Biological, Environmental and Rural Sciences at Aberystwyth University. I am scheme coordinator for Microbiology and related degree schemes (C500, C501, C502, C509 and CC35) and for the postgraduate MRes Biosciences (C190). I am also an elected member of AU Senate and Council.Graduate of Aberystwyth University with a BSc in Zoology and Microbiology and a PhD on Flow Cytometry of Microorganisms.



Member of the Microbiology Research Group in IBERS.

Current focus

Microbial physiology using the model organism Saccharomyces cerevisiae in a biotechnologically relevant setting to understand viability and vitality, stress response and heterogeneity. Methods include flow cytometry, radio-frequency impedance spectroscopy, barcode arrays and multivariate data analysis methods. Part of this work is undertaken collaboratively with AU spin-out company Aber Instruments Ltd.
