Current Research

Urban environments and the roads bisecting them contribute significantly to the high ambient levels of harmful pollutants, including particulate matter and oxides of nitrogen. These pollutants are detrimental to human health and, principal factors influencing the physiology and development of flora and fauna in urban centers. My research explores the effects urban pollutants have on invertebrate behaviour, with particular emphasis on invertebrate memory and cognitive ability. Using the European honey bee (Apis mellifera) as a model species, I principally investigate the effects of urban pollutants, including those associated with roads and vehicle exhaust, on the recognition and memory of floral-odours by honey bees.
