Martin Blaser seeks to understand the relationships we have with our persistently colonizing bacteria.

His work over the past 30 years has focused on human pathogens, including Campylobacter species and Helicobacter pylori, which are model systems for understanding interactions of residential bacteria with their human hosts. Over the last decade, Blaser has actively studied the relationship of the human microbiome with humans in terms of evolution, persistence mechanisms, host-interactions and population dynamics. He has looked at extinctions of ancient microbiota constituents. This research has implications for health, relating to asthma, obesity, diabetes and allergies.
