Senior Research Fellow and former Director. Colin's research addresses fundamental aspects of the biology of the marine organisms that are of critical importance in regulation of the Earth’s climate, and which also provide ideal models for understanding fundamental aspects of cell biology. He has a primary focus on cellular transport, homeostasis and signalling in phytoplankton and multicellular algae. He studies environmentally important groups, such as the calcifying coccolithophores and adopts a multidisciplinary approach to understand the molecular mechanisms underlying major biogeochemical processes. A key strategic driver of much of this research is to provide a better understanding of how phytoplankton populations may respond or adapt to changing conditions in the oceans, including ocean acidification. Colin also uses model algal systems such as Fucus and Chlamydomonas to understand the molecular mechanisms underlying signalling in cells and flagella. Along with comparative physiological and genomic studies this research is shedding new light on the evolution of signalling mechanisms in eukaryotic organisms.
