Summary

For almost 30 years, Dr Hardege has studied how animals use chemical signals. Our understanding of senses has greatly improved, but our knowledge of the importance of smell and odour in animal, microbial and plant communication systems is still relatively weak. This is challenging in the face of climate change with the reduction in the oceans' pH affecting marine organisms' ability to use chemical signals. We currently have no realistic idea as to whether animal signalling systems can adapt or have the plasticity to overcome what is known as 'olfactory disruption'. Most of Dr Hardege's research focuses on this topic.

Postgraduate supervision

Dr Hardege welcomes MSc and PhD projects that deal with animal ecology and physiology, especially when research on animal olfaction is involved. His research group also has a major interest in applied projects in areas such as aquaculture and pest control, developing sensor for animals, plant fitness and research related to the impacts of climate change (i.e. ocean acidification). These are encouraged, as are projects linking these to past extinctions or predicting future extinctions. The group's work spans areas from behaviour to physiology, including molecular aspects as well as chemistry. Completed PhDs Over the past 17 years, Dr Hardege's research group has hosted 10 PDRAs and more than 40 postgraduate students, most of whom are now in academic positions worldwide - including in China, the USA, Portugal, Uruguay, Germany, Ghana, Saudi Arabia, Egypt and the UK. Some 18 PhD research projects have been completed under his supervision, with all but one of these externally funded.
