Craig W. Roberts obtained a BSc (Hons) in Parasitology from the University of Glasgow and then completed a PhD in Immunology at the University of Strathclyde. During his PhD, he studied immunological control of Toxoplasma gondii infection.  A Fulbright Scholarship allowed him to spend 2 years in the USA where he continued his work on this protozoan parasite at the University of Chicago. As Professor of Parasitology, he is currently active in four broad areas: (i) the interaction of Toxoplasma gondii with its host, and how this knowledge can be harnessed to effectively control or vaccinate against this parasite; (ii) the influence of sex and pregnancy-associated hormones on immunity; (iii) identification, validation, and exploitation of antimicrobial targets in Acanthamoeba; and (iv) drug delivery systems for difficult-to-treat pandemic-capable and emerging pathogens. Craig Roberts contributes to teaching undergraduate and postgraduate degrees in SIPBS.
