Cameron Alexander is "Associate Professor & Reader in Advanced Drug Delivery" at the University of Nottingham.
As I understand it, a major part of his work is creating large molecules to act as "Trojan Horses", allowing better deliver of anti-cancer drugs to their intended destinations.
Although I think Cameron (a man with a knack for using analogies to describe his work) seems to prefer comparing the method to Russian dolls, rather than Trojan horses!
Either way, you can watch the video above to see him talk more about himself and the science he's involved with.
Part of it involves the area of synthetic life, which coincidentally has been in the news quite a bit lately.
