Welcome to the "De Roode" lab at Emory University.

We are in the Department of Biology and the Population Biology, Ecology and Evolution graduate program.

We study the ecology and evolution of parasites and their hosts as well as the genetics of monarch butterfly migration.

We use monarch butterflies, human malaria, honeybees, fruit flies and worms to understand the evolution of parasite virulence, animal medication and drug resistance.

In addition to our research, we teach pre-college, undergraduate and graduate courses, and also organize outreach to the community.


Latest news

Summer 2016

Jaap worked with Ted-Ed to produce an online lesson on the parasite Toxoplasma. See video to the right and the full lesson here.

Undergraduate student Helen Li and former graduate student Amanda Pierce published a paper in Animal Migration, showing that migratory monarchs have evolved bigger wings than non-migratory monarchs.

Leiling Tao and Kevin Hoang showed that the use of medicinal plants by monarchs comes at substantial costs, akin to the side effects of many drugs.

Jaap taught an Emory course on insect biology at James Cook University. See photos here.

Spring 2016

Congrats to Mary, Zach and Travis for publishing papers on within-host competition in human malaria, fruit fly immune system evolution and population genetics of honeybee Varroa mites respectively. And Andrew Mongue and Michelle Tsai showed that monarch butterflies can suffer from inbreeding depression.

Congratulations to Michelle Tsai, Kevin Hoang, Jessie Cai and Aamina Ahmed, who graduated from Emory College.

Jaap de Roode's, Nicole Gerardo's and Mark Hunter's grant application on monarch immunity and gut microbiome was recommended for funding by NSF. The aims of the project are to study how milkweeds affect monarch resistance to parasites by altering immunity and gut microbiota.

Fall 2015

Belowground mycorrhizal fungi can indirectly affect monarch butterfly disease by altering milkweed chemistry. See Leiling's new paper in Proceedings B and news article in Science.

Kevin and Jaap organized workshops at the Chautauqua Weekend Event on The Rosalynn Butterfly Trail in Plains, Georgia, with President and Mrs. Carter. See photos here.

Jaap started his one-year sabbatical at the University of Amsterdam, and co-authored a Science review on the community ecology of infectious disease.

Summer 2015

Amanda is now Dr. Amanda, after having successfully defended her PhD thesis. Congratulations!

Spring 2015

Jaap worked on an online lesson on parasites with TED-Ed. See the video to the right and this link to the full lesson.

Members of the de Roode lab will present monarch butterflies at the Wild Poisons Day at Fernbank Museum of Natural History on Saturday March 14.

Jaap talked about Darwinian Medicine at the Darwin Day Dinner, organized by the Atlanta Science Tavern.

Male monarchs can pass on food-derived parasite protection from their milkweed food plants to their offspring. See our paper in the Journal of Animal Ecology.

Fall 2014

Jaap co-authored a paper in Nature that identified genes involved in monarch migration and warning coloration. The paper was a collaboration led by Marcus Kronforst (University of Chicago) and Shuai Zhan (Chinese Academy of Sciences). See news coverage in Nature, Science, the New York Times and National Geographic.

Erica received a pre-doctoral research development grant from the Social Science Research Council Mellon Mays Graduate Initiatives program for her work on the effects of milkweeds on the monarch butterfly microbiome. And Amanda received an EDEN Research Exchange Grant to visit Marcus Kronforst's lab to further her work on monarch migration genetics. Congrats to both!

Jaap gave a talk on animal self-medication at TEDYouth in New York (see video on the right). For an interview, see here.

Kevin, Michelle, Jaap and his children attended President Jimmy Carter's 90th birthday, at which the new Jimmy and Rosalynn Carter pollinator garden - built in collaboration between the Carter Center, Trees Atlanta and the De Roode lab - was opened. A news story can be found here.

Monarchs dispersed from North America across the Pacific and Atlantic Oceans, losing genetic diversity in the process. See our paper in Proceedings of the Royal Society Series B here.

Amanda won the first Graduate Program in Biology Academic and Professional Achievement Award.

Welcome to Wen-Hao Tan and Signe White who joined the PBEE program and are doing their first research rotations in the De Roode lab, and undergraduate student Sasha Heaven.

Summer 2014

Several lab members joined Trees Atlanta and Carter Center staff and volunteers to create a pollinator and monarch garden at the Carter Center.

Amanda published her paper on monarch butterfly population genetics in Hawaii in PLoS One. The paper can be found here.

Spring 2014

Welcome to Aamina Ahmad, who joined our lab in May. And goodbye to Jessica Nguyen who graduated from Emory.

Jaap, Andrew and Camden developed and taught a new 3-week course on insect biology. Read more here.

Camden and Andrew both received multiple offers from graduate schools and decided to join the University of Michigan and the University of Kansas respectively. Congratulations and good luck!

Erica and Travis received NSF Graduate Research Fellowships. Many congratulations!

Congrats to Michelle and Itai, who were admitted to the SURE program to continue working in the lab during summer 2014.


Research Highlights    

Infectious diseases are part of ecological communities. Insights from community ecology are crucial to control infectious diseases. See our review in Science.

  Drug-sensitive malaria parasites suppress resistant parasites in human infections, potentially slowing down resistance spread. See our paper in Proceedings of the Royal Society Series B.
