Contact Details


Dylan Gwynn-Jones joined Aberystwyth University in 1999 and is currently a Reader in the IBERS Ecology Group. He previously worked as a post-doctoral researcher at the Universities of Sheffield (1994-1999) and Manchester (1992-1994) engaging with research on several European projects. Research targeted the effects of future elevated carbon dioxide and UV stress impacts on plants and communities. This followed a Ph.D. at Bangor University (1989-1992) jointly with CEH Bush in Edinburgh on the future effects of elevated carbon dioxide on trees.    

His research interests on elevated carbon dioxide and also plant stressors continue to the current day but has diversified to also include agricultural and horticultural crops. He now investigates ‘stress tools’ and using stressor exposure to manipulate plant chemistry and crop quality.    

Dylan teaches is a highly experienced teacher, a Fellow of the HEA and delivers modules to a broad range of degree scheme at undergraduate and post-graduate levels at IBERS.
