Callum Gray

Dr Callum Gray is a Research Fellow at the School of Biological and Behavioural Sciences, Queen Mary University of London, where he is a member of Dr Christopher Duffy's Research Group. His work is funded by the Leverhulme Trust project "Photosynthesis on Alien Worlds: What might it look like, and can it be detected?" within the Centre for Molecular Cell Biology.

Gray's research spans photosynthesis, astrobiology, and biophysics, integrating computational biology and theoretical physics to investigate light-harvesting mechanisms. He employs thermodynamics, machine learning, and fluorescence spectroscopy to model energy transfer processes in biological systems, with particular focus on extraterrestrial applications and photoprotective mechanisms in plants.

His publication record reveals a cohesive trajectory centered on photosynthetic biophysics, where computational modeling bridges experimental simulations and theoretical frameworks. Recent work demonstrates increasing emphasis on machine learning approaches to predict light-harvesting diversity and detect potential biosignatures in alien environments, while maintaining foundational contributions to understanding fluorescence kinetics and energy transfer in protein complexes.

Gray actively contributes to the Leverhulme Trust-funded "Photosynthesis on Alien Worlds" project, collaborating within Dr Duffy's research group to develop detectable signatures of photosynthetic processes on exoplanets. This work positions him at the intersection of astrobiology and molecular biophysics, with implications for future space-based observational missions.
