Hermes Gadelha is mathematician who does biology. His work focuses on the synergy between mathematics and biology, encompassing areas in human and animal reproduction, such as sperm swimming dynamics, biomechanics of cytoskeletal filaments and flagella, plus bio-inspired artificial swimmers and micro-robots, membrane separation processes and water desalination, as well as pattern formation in viscous flows. Following his DPhil in Mathematics at the University of Oxford, Dr Gadelha worked as an independent scientist at the University of Cambridge, based at Trinity Hall, and later in Oxford as a Hooke Research Fellow. Today, he is a Lecturer in Applied Mathematics at the University of York, and an honorary Lecturer at the Centre for Human Reproductive Science, Birmingham Women’s NHS Foundation Trust.
