Steve Paterson research focuses on the causes and consequences of genetic diversity in host-parasite interactions. He has worked on helminth infections since his PhD, where he investigated MHC diversity and nematode resistance in Soay sheep, followed by post-doctoral work on genetic diversity within Strongyloides populations.

In the last 10 years he has pioneered genomic and bioinformatic approaches to reveal genetic diversity in natural, experimental and clinical populatons of hosts and parasites. With colleagues, he led the first genome sequence analysis of Fasciola hepatica, revealing the complexity and genetic diversity of this important veterinary pathogen.

He is a director of the Centre for Genomic Research at the University of Liverpool, which is one of the foremost genomics facilities in Europe with a strong track-record in pathogen genomics.
