People

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

Saumik Basu

Saumik is studying molecular and biochemical aspects of our model pea aphid-virus-legume system

Rob Clark

Rob is studying how host plant variation and predator effects impact aphid-virus vector biology in legumes

Graduate Students


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


Liesl Oeller
MS Candidate in Entomology
Liesl is conducting research on the pest communities in quinoa crops, and determining host plant resistance of quinoa against various pest species

Lab Alumni (Graduate Students and Postdocs)


Paul Chisholm
PhD in Entomology (May 2017)

Paul studied plant-insect-virus interactions, using the pea aphid and legumes as a model system. He currently works for the US Forest Service

Dr. Ivan Milosavljevic
PhD in Entomology (August 2015)
Postdoc (2015-2016)

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
Postdoc (2016)

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
Postdoc (2013-2015)

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 (August 2015)

Lizz developed decision-support tools in Geographical Information systems to improve pest management for potato cropping systems



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