Areas of Research
Ecology and Evolution of Host-Parasite Interactions
Welcome to our research lab! We study various aspects of ecology and evolutionary biology, including the dynamics of host-parasite interactions, the evolution of immune systems, and the ecology of infectious diseases. Much of our work focuses on monarch butterflies and their parasites, asking how the milkweeds that monarchs use as caterpillars affects their susceptibility to parasite infection. We have also studied how beekeeping practices drive the spread of infectious disease in honey bees, and are currently investigating whether bees can use fungi to mitigate disease.
Genetics and Behavior
One exciting way in which animals can protect themselves against infectious diseases is by using medication. We study such behaviors in monarch butterflies, which can use toxic milkweeds as medicine, and in honey bees, where we are asking if bees can utilize fungi as medication. Another fascinating behavior we study is animal migration. Monarchs travel thousands of miles each year to reach overwintering sites in Mexico, and we study how monarchs navigate, and how this migration can help in keeping parasites at bay. As part of this work, we also study the population genetics of migratory and non-migratory monarchs around the world.
Science Communication
Communication is a key aspect of our research lab. We are passionate about effectively communicating scientific concepts to diverse audiences. From educational materials to engaging videos, we aim to make science accessible and captivating for everyone.
Our Team
Our research lab has a diverse team with members from different backgrounds. Over the years, we have had team members from many countries, including the Netherlands, United States, France, China, Taiwan, Iran, England, India, Saudi Arabia, Spain, and Nigeria. Our team generally consists of research specialists, postdocs, PhD students and undergraduate students.
Jaap de Roode
Samuel Candler Dobbs Professor of Biology
Jaap received his MSc in Population Biology from Wageningen University in the Netherlands and his PhD in Evolutionary Biology from the University of Edinburgh in Scotland. He is interested in the ecology and evolution of infectious diseases, and currently studies infectious diseases of monarch butterflies and honey bees.
Erik Edwards
Greenhouse Manager
Erik obtained a Bachelor of Agricultural Sciences at the University of Georgia and has worked as grower at several commercial greenhouses. He is in charge of the Biology Department’s greenhouse, and and the Educational Gardens on the Emory Campus.
Tiana Scott
Lab Manager
Tiana graduated from Emory University with her BS in Biology. She is the research specialist for the de Roode and Gerardo labs. She is interested in the impact of environmental change on species interactions.
Nadya Muchoney
NSF Postdoctoral Fellow
Nadya obtained her PhD from the University of Nevada, Reno, where she studied the role of host plant chemistry in anti-viral immunity in butterfly hosts. She is currently investigating how milkweed chemicals shape monarch midgut microbiomes, and how midgut microbes contribute to resistance against a protozoan parasite.
Ehsan Sanaei
Postdoctoral Researcher
Ehsan obtained his PhD from the University of Queensland, and carried out postdoctoral research at Griffith University. His main interests involve insect-microbe interactions. Having studied Wolbachia endosymbionts in scale insects, he is now using monarch butterflies to study the role of gut microbes in driving resistance to parasite infection.
Sara Gotkin
Undergraduate Student
Sara is a biology major at Emory University who is interested in the role of milkweed plant chemicals and other plant defenses in driving monarch-parasite interactions.
Julie Kong
Undergraduate Student
Julie will be studying biology or neuroscience, with a view to apply for medical school in the future. With a lifelong passion of studying monarch butterflies, she joined the de Roode lab to carry research on the interaction between monarchs, milkweeds and parasites.
Saanvi Mylavarapu
Undergraduate Student
Description: Saanvi’s academic interests lie at the intersection of biology and environmental science. She has worked on community efforts to support pollinators and expand milkweed habitats, experiences that sparked her curiosity about the complex ecology of monarch butterflies. She is interested in investigating the ecological dynamics between pollinators and their host plants.
Morgan Hampton
Undergraduate Student
Morgan is a first year at Emory University intending to major in Environmental Science. She is interested in researching the effects of cardenolides on monarch-parasite interaction as part of the De Roode lab.
Annika Bandaru
Undergraduate Student
Anika is intending to major in Human Health and is aiming to attend medical school. She has always had a special interest in butterflies, so she is excited to bring this fascination alive by researching the interaction between monarchs and parasites as well as the genetics between different populations.
Halley You
Undergraduate Student
Halley is a freshman planning to major in Biology. He is interested in host–parasite coevolution and in understanding the evolutionary dynamics between monarch butterflies and their parasites.
