I have a broad interest in the causes and consequences of phenotypic variation within species. Much of my work has operated at the intersection of physiology and ecology, a theme that I am continuing with in my Marie-Skłodowska Curie Fellowship, in which I am collaborating with Prof. Sigurd Einum on the European Union Horizon 2020 research and innovation programme funded project ‘Adaptive plasticity meets unpredictability: how do organisms cope with changing environmental variability?’ In my fellowship, I am using the freshwater cladoceran Daphnia magna to investigate phenotypic responses to changing patterns of temperature variability: chiefly can organisms detect levels and predictability of environmental variation? How can they respond to this through phenotypic plasticity and could there be potential for such plasticity to evolve given its specific costs and benefits?
