WSU Department of Entomology

Crowder Laboratory


Principal Investigator

Dr. David Crowder

Dave Crowder, Assistant Professor

I use theory, experiments, and observational studies to understand the impacts of land-use and environmental variability on the structure and function of insect and plant communities. more

Lab Technician

Matt Brousil

Matt has been the lab technician since 2017. He helps coordinate all of the research projects in the lab. He has a MS in Forestry Sciences from California Polytechnic Institute.

Postdoctoral Scientists

Robert Schaeffer

Robert is studying cross-kingdom interactions involving plants, pollinators, and microbes in natural and agricultural systems

Graduate Students

Paul Chisholm
PhD Candidate in Entomology.

Paul is studying plant-insect-virus interactions, using the pea aphid and legumes as a model system.

Eli Bloom
PhD Candidate in Entomology.

Eli is studying the stability and diversity of native pollinator communities in urban and organic farming systems.

Robert Orpet
PhD Candidate in Entomology (co-advised by Vince Jones)

Robert is determining if woolly apple aphid densities in organic and conventional orchards can be explained by factors such as soil quality, nutritional status of apple trees, and the presence of aphid predators and parasitoids.

Rachel Olsson
PhD Candidate in Entomology

Rachel is a recent graduate of The Evergreen State College. Her research interests include studying pollinator health and how interspecific interactions between pollinators affect foraging. Outside of the lab, Rachel enjoys knitting, listening to bluegrass music, and tasting new craft beers.

Abigail Cohen
PhD Candidate in Entomology

Abigail is working on the ecology of potato psyllids in the Pacific Northwest to understand the environmental and landscape-level factors affecting psyllid populations and Liberibacter pathogens. Abigail is also conducting experiments studying the ecology of psyllid-Liberibacter-potato interactions.

Ben Lee
PhD Candidate in Entomology

Ben is doing research on the influence of predatory insects on herbivores and the spread of plant viruses using peas as a model system. He is an amateur chef and a strong proponent of supporting local foods and farmers, and is excited to help benefit agricultural systems through research

Maggie Freeman
MS Candidate in Entomology

Maggie is conducting research on the effectiveness of parasitoids for providing biological control of lily leaf beetle

Undergraduate Students

Akaisha Charlton
Pursuing BS in Agricultural Biotechnology

Akaisha is conducting experiments to assess whether inter-cropping can reduce the spread of vector-borne pathogens.

Lucy Eggleston
Pursuing BS in Organic Agriculture

Lucy has worked in the lab since 2015, primarily on our pollinator project.

Harriet Harris
Pursuing BS in Organic Agriculture

Harriet has worked in the lab since 2016, assisting with our pollinator projects

Abagail Poelstra
Pursuing BS in Environmental and Ecosystem Sciences

Abby has worked in the lab since 2016, assisting with all of our research projects

Madison Armstrong
Pursuing BS in Biological Sciences

Madison has worked in the lab since 2017, assisting with all of our research projects

Lab Alumni (Graduate Students and Postdocs)

Dr. Ivan Milosavljevic

Ivan studied the biology, ecology, and management of wireworms, a devastating pest of wheat throughout the Pacific Northwestern United States. He did his PhD and a brief postdoc in the lab. He currently works as a postdoc at UC Riverside more

Dr. Eric Moise

Eric studied community and disease ecology, using the potato psyllid and Solanaceous plants as his model system. He is currently a research leader at the Canadian Forest Service

Dr. Elinor Lichtenberg

Dr. Elinor Lichtenberg

Elinor’s research focused on the effects of farming landscapes on pollinator behavior and interactions between pollinator species. She is currently a postdoc at the University of Arizona

Elizabeth D’Auria
MS in Entomology.

Lizz developed decision-support tools in Geographical Information systems to improve pest management for potato cropping systems. She graduated with her MS in 2015.

Elliott Moon
MS in Statistics (co-supervised with Bill Snyder).
Elliott studied landscape ecology of herbivorous and predacious insect communities. He graduated with his MS in 2013.
