Nichar is broadly interested in understanding the mechanistic processes that operate between ecological conditions and outcomes of health relevance. Her current research explores the impact of land-use change on the dynamics of mosquito-borne disease transmission, as mediated by effects on mosquito vector life histories. Her fieldwork is carried out at the Stability of Altered Forest Ecosystems (SAFE) project sites in Malaysian Borneo, and her laboratory work at Imperial's Silwood Park campus. She is co-supervised by Dr Rob Ewers and Dr Lauren Cator.
Nichar is a NERC-funded scholar on the Science and Solutions for a Changing Planet (SSCP) Doctoral Training Partnership at the Grantham Institute for Climate Change and the Environment.
