Mark Jermy obtained his BSc Hons. in Physics from the University of Birmingham, UK, in 1993 and his Ph.D. from the University of Kent, UK, in 1997. He worked for the UK Ministry of Defence and Cranfield University before coming to the University of Canterbury in 2005. He teaches fluid mechanics to engineering undergraduates and forensic scientists. His research mostly concerns particles carried by fluids: potentially infectious droplets and aerosol exhaled by humans, blood droplets at crime scenes, silica particles in geothermal fluids, and fuel droplets in combustors. He has also worked on gas flows in the human upper airway during non-invasive ventilation and cyclist aerodynamics.
