The Garvin lab studies the ecology of disease.

Our primary focus is the transmission of parasites and viruses in wild bird populations, specifically the role of volatile and semi-volatile chemicals in the interactions between birds and mosquito vectors of virus. We’re especially interested in understanding the role of bird preen gland secretions in attracting mosquitoes to birds that serve as reservoir hosts of West Nile.

In collaboration with chemist Rebecca Whelan of the University of Notre Dame, over the past decade we’ve conducted field and lab studies to describe intra-and inter-specific variation in the components of the secretions. Most recently we’ve conducted lab bioassays to test for the effect of these compounds on mosquito blood meal choice. For this work, we maintain a mosquito colony, featured in 2018 senior Cella Wright’s award-winning documentary video .

We are also studying local tick populations to determine the prevalence of three bacterial infections, including Borrelia burgorferi, the causative agent of Lyme disease. This study is in collaboration with Ryan Ragland  ’00 of Biomeme Inc., who is involved in the development of the mobile DNA detection technology that we are currently using.

A third focus of our lab is the detection of heavy metal carcinogens in Eastern Cottonwood trees in a local cancer cluster. Through this work, a collaboration with geochemist Johan Schjiff of the University of Maryland, geologist Greg Wiles of the College of Wooster, and Rebecca Whelan, we seek to determine if abundance of carcinogenic heavy metals in samples collected within the cluster area is higher than those collected in adjacent areas.

I teach the following courses:

  • BIOL 200 Genetics, Evolution, and Ecology with Katherine Cullen, Mike Moore, and Angie Roles
  • BIOL 308 Disease Ecology and BIOL 320 Invertebrate Biology, both lecture and lab courses with field components and semester-long research projects
  • First Year Seminar 116 Ecology of the Vermilion River Watershed, in which place-based experiential learning involves weekly field trips to the local watershed. 
  • BIOL 501/502  Mentored Research, through which students belong to a research community and experience all of the joys and sorrows of the scientific process. Refer to the publications section to see the results of our work.

Oberlin to Launch Integrative Concentration in Global Health

December 1, 2020

Oberlin College will launch an integrative concentration in Global Health in fall 2021, recognizing that worldwide threats to mental and physical wellness are most successfully addressed with the holistic, interdisciplinary approach that is the core of liberal arts education.

The Teaching Garden

August 21, 2020

This academic year, many students will learn in outdoor classrooms and some will have the opportunity to explore Oberlin’s pollinator garden—a living classroom inside the Science Center.
