I am retired and no longer run a laboratory of my own or supervise PhD students. I am still involved in collaborative projects with Ben Miller's lab at UEA, and with colleagues in labs in Spain, China and Saudi Arabia. Much of this work centres on varied aspects of coastal, aquatic and arid ecosystems, particularly where salinity and water stress are significant selection pressures. I am interested in the practical application of ecological principles for habitat restoration, conservation and sustainable land use.
