A lot of people think of mosquitoes as being all the same, but did you know that Ohio has around 73 different species of mosquitoes? We know a lot about some of them, but very little about others, and my lab is working on determining how the mosquito microbiota affects our mosquitoes during their entire lifespan from larvae to adulthood.
Mosquitoes aren't the only disease vector in Ohio; ticks are common and tick-borne diseases such as Lyme disease are expanding rapidly. There has historically been much less research into ticks than mosquitoes, and there are several basic questions that we still need to answer about the tick microbiota and immune system, which we are working to address.
I also have a number of smaller ongoing projects, all at least tangentially related to disease ecology. These include looking at chytrid fungal infections in local amphibians, the alterations brought about by changing lawn care practices and many other things. If you have an idea you'd like to pursue, let me know and we'll see if we can work something out.
Following a brief stint working as a microbiology reviewer at the FDA, I returned to academia working at HMX, the online learning group for Harvard Medical School. My primary duties there were to create new online courses in immunology, I was also interested in researching the effectiveness of online courses. With other members of the HMX team, we looked at a variety of questions related to online learning that may help people create better online and in person courses.

I conducted post-doctoral research in the laboratory of Dr. Christopher Plowe in the Division of Malaria Research at the University of Maryland, Baltimore Institute for Global Health. The laboratory studies multiple facets of malaria transmission and immunity, and has field sites in Myanmar, Malawi, Mali, and other malaria endemic countries. IĀ helped with various aspects of the group's research, including leading the entomological efforts in Myanmar and Malawi, but much of my research centered on the serological response of the human adaptive immune system to Plasmodium infection.

To pursue my PhD, I moved to Dr. George Dimopoulos' laboratory at the Johns Hopkins Bloomberg School of Public Health Department of Molecular Microbiology and Immunology. Dr. Dimopouos' group works on various aspects of mosquito biology as related to vector-borne disease control. Some members of his lab study the tripartite interactions between mosquitoes, human pathogens, and endosymbiotic bacteria, while others work on applications of the insect innate immune system for disease control. I was in the latter group, and my thesis work focused on the physiological changes and fitness effects brought about by genetic modification of mosquitoes to make them resistant to Plasmodium falciparum infection.

During my years as a Master's student at Michigan State University, I worked in the laboratory of Dr. Zhiyong Xi on the three-way interactions between the dengue virus, the bacterium Wolbachia and their mutual host Aedes aegypti. This was my first intense biology research, and has formed the basis of my future vector-borne disease work. I measured the effects of Wolbachia infection on various aspects of mosquito fitness and changes in the ability of dengue virus to infect mosquitoes in the presence or absence of the bacteria.

My first research experiences occurred while I was an undergraduate student at Oberlin College. I got my start working with mosquitoes while performing independent research on the possibility that Culiseta melanura mosquitoes acted as a reservoir to maintain West Nile virus over the winter. However, the majority of my research was in the mathematics department. There, I worked with Bob Bosch on the application of math to creating visual art.
