Gerry Crossan is a programme leader at the MRC Laboratory of Molecular Biology (LMB), University of Cambridge, and concurrently serves as a Governing-Body Fellow and Research-Fellowships Secretary (STEM) at a Cambridge college, placing him at the intersection of cutting-edge research and academic governance.
His research seeks to understand how genetic information is transmitted faithfully across generations, with a particular emphasis on the mechanisms that protect germ-line cells from DNA damage. Trained in DNA-interstrand-crosslink repair, he pioneered studies revealing how endogenous aldehydes—common by-products of metabolism and alcohol—create genotoxic stress, damage chromosomes and fuel stem-cell mutation. His work delineated the Fanconi anaemia DNA-repair pathway as a critical guardian against such damage, demonstrated that maternal aldehyde detoxification during pregnancy safeguards the fetal genome, and identified SLX4 as a key tumour-suppressor/nuclease regulator whose loss phenocopies Fanconi anaemia. More recently his programme has expanded to primordial-germ-cell biology, demonstrating that translesion DNA synthesis is essential for genome-wide demethylation and normal germ-cell development, and uncovering protective roles of Fanconi proteins against retrotransposon activity.
Across more than two dozen high-impact publications (Nature, Nature Genetics, Molecular Cell, Blood) a clear trend emerges: integration of biochemical, genetic and whole-animal approaches to expose how everyday metabolites threaten genome integrity, how defined repair pathways counteract these threats, and how failure of such defences precipitates developmental abnormality, bone-marrow failure and cancer. These insights are already informing therapeutic strategies, exemplified by his proposal to repurpose metformin to mitigate aldehyde stress in Fanconi anaemia patients.
Within Cambridge he contributes to collegiate governance and to the selection and mentoring of incoming research fellows, underlining his commitment to nurturing the next generation of scientists.
