José C. Casas-Martínez is a postdoctoral researcher in Physiology at the University of Galway with a BSc in Biochemistry from the University of Córdoba and a PhD in Molecular Physiology from the University of Galway, with over five years of research experience in redox biology, ageing, and cellular stress responses. His research sits at the interface between fundamental molecular mechanisms and translational medicine, with a particular focus on mitochondria–endoplasmic reticulum (ER) communication, redox signalling, and stress adaptation in ageing and disease.

He completed his doctoral training at the University of Galway, where his work elucidated how adaptive ER stress and redox regulation shape mitochondrial remodelling, longevity, and cellular resilience through mitochondria–ER contact sites (MERCS). His research has resulted in multiple peer-reviewed publications in high-impact journals, including Cell Death & Differentiation, Cellular and Molecular Life Sciences, Redox Biology, and Molecular Metabolism.

Currently, his postdoctoral research focuses on the development of novel TRPA1-targeting therapeutics derived from marine compounds for the treatment of knee osteoarthritis, funded through the Disruptive Technologies Innovation Fund. He has also contributed to academic–industry collaborations aimed at developing innovative medical devices for vascular disease. Alongside his research, he is actively involved in undergraduate and postgraduate teaching within the Department of Physiology.
