My research interests are focused on insect-microbe interactions across ecosystems and decomposition ecology. I am interested in the use of next generation genomic methodologies to answer both basic and applied research questions focused on the successional changes of microbial communities commonly associated with insects in aquatic and terrestrial habitats.
Current assignment: Research 95% | Teaching 5%
My current teaching program consists of co-teaching a one-credit advanced undergraduate/graduate course on “Forensic Applications of the Necrobiome”. Students will learn about the interactions within the community of necrophagous organisms, defined as the necrobiome (e.g., necrophagous insects and microbes), during decomposition of animal carrion and human corpses.
I am interested in basic research questions focused on insect-microbe interactions using an interdisciplinary research approach. My research interests, background, experiences have developed into a comprehensive ecological, genomic, bioinformatic, and statistic analytical ‘toolbox’. This toolbox allows me to pursue a range of research topics using high-throughput genomic techniques (e.g., amplicon based sequencing).
Specifically, my research is centered on those questions to better understand the biological mechanics governing decomposition across ecosystems, which is a vital biological process for all ecosystems including agricultural crops to freshwater streams to forested habitats. I am also interested in exploring other research avenues that have more directed and applied research questions to solve real-world problems (e.g., insects as alternative protein sources, insect use for organic biodegradation, and use of the human post-mortem microbiome for use in forensic investigations). Currently, I am funded by the National Institute of Justice to characterize the human post-mortem microbial community structure from cadavers during routine death investigations.
