Jeff Liu

Jeff Liu (Ta-Chun Liu) is a Taiwanese-born scientist and entrepreneur whose career spans computational biology, genomics, and microbiology diagnostics. He completed a DPhil at the University of Oxford, where he developed expertise in single-cell analysis and machine learning applied to microbial identification. Before his doctoral work at Oxford, he conducted research at Academia Sinica in Taiwan — one of the world's leading research institutions — as well as at the California Institute of Technology, where he gained experience in structural biology.

In 2022, Liu co-founded Ramanomics as an Oxford University spinout, applying Raman spectroscopy and machine learning to one of the most pressing problems in modern medicine: rapid identification of pathogens and their antimicrobial resistance profiles. As CEO, he leads a company whose platform can deliver results from clinical samples in under three hours — compared to the three-day wait under current standard-of-care methods.

Ramanomics has received grant funding from Innovate UK, was recognised by the UK Government as one of the country's most innovative young companies, and raised £1.8 million in 2025 to accelerate development of its culture-free diagnostic era. The company's work has particular relevance to the global antimicrobial resistance crisis, offering clinicians actionable resistance profiles at the bedside.
