Professor Doug Kell is a systems biologist who has been studying anomalous clotting for many years, and since the pandemic began has turned his knowledge, working alongside Prof. Resia Pretorius, to explore the theory of microclots in Long Covid patients.  In this week's episode Prof. Kell explains to us the way in which these clots form, his theories behind what is occurring, and what are the current, albeit anecdotal, treatment strategies.
