I am a quantitative disease and community ecologist. I am especially interested in disease ecology in the context of global changes such as biodiversity loss, climate change, and environmental eutrophication. I like to approach my research by combining three iterative and complementary perspectives: observations in nature inspire relevant questions, experiments test specific predictions, and mathematical models generalize and formalize theory. I mostly work in aquatic systems, focusing on parasites that infect zooplankton, but I also have a few projects in terrestrial grasslands.<\/p>\n\n\n\n

I am interested in understanding how aquatic invertebrates are affected by their environment. I am especially focused on plankton community dynamics and drivers of ecosystem change. I received my BS in marine biology from The University of New Haven in 2020, and am currently finishing my MS in Environmental Science & Ecology from SUNY Brockport. In my masters program I worked with Dr. Michael Chislock to understand how nutrient driven algal blooms and microplastics work interactively to impact aquatic communities with a focus on zooplankton community structure, and Daphnia<\/em> and the amphipod Hyallella azteca<\/em>‘s life history characteristics. <\/em> I am excited to combine my past experience with current and future research in the Strauss Lab.<\/p>\n\n\n\n

I am a parasite ecologist who works toward understanding host-parasite relationships over multiple spatiotemporal scales and am funded by a postdoctoral fellowship from Center for the Ecology of Infectious Diseases through the Provost\u2019s initiative on data science, artificial intelligence, modeling, and infectious disease dynamics. This includes everything from global trends at higher host-parasite taxonomic groupings to within-host parasite dynamics in a single location, from ecological to evolutionary timescales, and from single host-parasite populations to host-parasite communities. In particular, I seek to understand the eco-evolutionary dynamics of complex lifecycle parasites by leveraging data science approaches to uncover patterns in large datasets. To this end, I am interested in understanding macroecological and phylogenetic patterns in the evolution of complex parasite lifecycles with multiple hosts. I work with the Strauss lab using Daphnia<\/em> parasites, such as microsporidians and Alloglosidium<\/em> sp. trematodes, to understand how intermediate hosts are added and dropped from parasite lifecycles. Thus, I use fieldwork, benchwork, and computational methods to address host-parasite relationships across multiple ecological and evolutionary scales.<\/p>\n\n\n\n

I’m interested in the interactions between disease spread and community and ecosystem ecology. I especially enjoy thinking about how environmental conditions affect disease transmission and ecosystem processes. My undergrad research spanned from microbial bioremediation of selenium to the effects of metal ions on nectar microbial communities to carbon cycling and fungal disease in grasslands. I’m excited to combine different parts of these previous research experiences and learn a whole bunch of new things!

I am interested in predicting disease outcomes in complex prey\/hosts, parasites, and predator communities and how these interactions shape immune responses, including the host\u2019s decision to resist or tolerate infection. Most of my early studies use the fantastic Daphnia-Metschnikowia system and have focused largely on trait-mediated indirect effects of predators on immune responses and disease in Daphnia populations. Going forward, I will combine field observations, experiments, and mathematical models to test some intriguing ideas, including the healthy herd and terminal investment hypotheses.

I am an undergraduate Ecology student at UGA interested in infectious disease in freshwater systems. The bulk of my work in the lab has been investigating how changing temperatures affect Daphnia <\/em>growth rates as well as their host-parasite relationship with  Metschnikowia bicuspidata. <\/em>I am specifically fascinated by the interaction of community composition, predation, and disease transmission. I plan on studying this further by continuing my work with the Daphnia-Metsch <\/em>system. <\/p>\n\n\n\n
