Welcome to the Searle Lab website!
Our lab studies infectious disease ecology in freshwater systems. We use a combination of observational, experimental, and modeling approaches to understand the effects of community structure and composition on infectious disease dynamics.

Undergraduate students from around Purdue presented the results of their research at the Undergraduate Research and Poster Symposium. Baylie, Juliana and Mackenzie all did an excellent job presenting their posters!
Juliana presenting her poster titled "The effects of food availability and disease on invasibility of a zooplankton population."
Mackenzie presenting her poster titled "Comparing feeding rates of two species of freshwater zooplankton."
Baylie presenting her poster titled "The effects of resources and parasitism on competition between a native and invasive zooplankton."

Congratulations to Hector on receiving a College of Science International Travel Grant and an Andrews Environmental Travel Grant! Hector will be using his CoS award to travel to the Latin American Congress of Herpetology in Ecuador this June and his Andrews grant to conduct field work in Costa Rica this summer.

Spencer Siddons has joined the lab as a Ph.D. student. Spencer recently earned his master’s degree from the University of South Dakota and is broadly interested in amphibian ecology, disease dynamics, and conservation. Welcome to the lab, Spencer!

Maggie and Baylie present the results of their independent projects at the Undergraduate Research and Poster Symposium. Maggie presented the final results of her honors thesis studying the effects of food availability on competition and infection in two species of Daphnia. Baylie presented the beginning of her honors work investigating the effects of predators on disease susceptibility.

Spring semester has begun and we have two new undergraduates joining us. Welcome to the lab, Baylie and David!
December 8, 2015
Freshman biology students present the results of their group projects from the course, “Year 1 Biology Lab: Disease Ecology” taught by Dr. Searle. The students learned how to design and conduct their own ecological experiments and present their results in a poster session. Mackenzie did a great job as the undergraduate teaching assistant for this course.

Hector Zumbado-Ulate has joined the lab as a Ph.D. student. Hector has a master’s degree from the University of Costa Rica and is interested in studying parasite-mediated competition in amphibians. Welcome to the lab, Hector!
Abbie has been busy sorting through soil samples to find D. pulex ephippia to hatch.
April 14, 2015
Maggie Wigren presented the results of the first half of her honor's thesis. She studied the effects of food availability on pathogen spore production in D. dentifera. She will be continuing this work throughout the next year.

Abigail Merrick has joined the lab as a full-time technician. Abbie recently finished her bachelor's degree in agronomy from Purdue University. Welcome to the lab, Abbie!
Everyone has been very busy in the lab lately. Kaitlin and Maggie are leading their first independent projects while Abby and Mackenzie are helping Dr. Searle develop a new lab course in disease ecology.
January 12, 2015
Spring classes have begun and we have three new undergraduates joining us. Welcome to the lab Maggie, Mackenzie and Abby!
August 25, 2014
Fall classes have begun at Purdue. One brave undergraduate (Kaitlin O'Leary) will be helping Dr. Searle set up the lab this semester. We have a lot of boxes to unpack!
