Dr Robert Sharwood is a VC Fellow / Senior Lecturer within the Hawkesbury Institute for the Environment and affiliated with the School of Science. His research interests centre on developing climate-adapted germplasm through discovering novel heat tolerant and drought resistance mechanisms/traits that contribute to improvements in carbon fixation under future climate scenarios. His program spans from the gene to the protein to alter the biochemistry of photosynthesis through synthetic biology approaches to ultimately tailor crops to the prevailing climate. He focuses on crops such as maize, cotton, wheat, canola and rice and a number of important Eucalypt species including E. camaldulensis and E. globulus.
To mitigate climate variability, he is currently developing a new research program to improve the performance of fruit and vegetable crops within a protected cropping scenario.
