Dr. Dillman has been interested in nematology since he was an undergraduate and joined the Society of Nematologists in 2004. His first interaction with UCR faculty was as an undergraduate; he was part of a soil ecology field trip, led by UCR, to the Republic of Moldova in 2005. He has lived in California since beginning graduate school in 2007. He is happily married and has two sons. He joined the faculty in the Department of Nematology in 2015.

Research Areas

We study host-parasite interactions from both perspectives, using insect hosts as models. Our interest is in how hosts recognize and initiate an immune response to parasites and how parasites evade and/or suppress immunity. We are working to identify and characterize effector molecules used by parasites to dampen host immunity or damage host tissue. Additionally, we also study parasite host-seeking behavior and olfaction using parasitic nematodes.  

From the host perspective we study how nematode parasites are recognized and the immune response that follows. To do this we use a variety of insect hosts. As part of this work, we study host immunity generally using bacterial pathogens, nematode parasites, and other immune insults. In studying immunity we differentiate the relative roles of resistance, the ability of the host to reduce or eliminate pathogen burden, and disease tolerance or the ability of the host to manage the effects of infections.
