My research interests are focused on insect-microbe interactions across ecosystems and decomposition ecology. I use high-throughput “-omics” and machine learning approaches to answer both basic and applied research questions, specifically focused on the successional changes of microbial communities associated with insects and decomposing organic materials.
Current assignment: Research 95% | Teaching 5%
My current teaching program consists of graduate seminar courses. Either a 1 credit advanced undergraduate/graduate course on “Forensic Applications of the Necrobiome” or a 1 credit graduate level course on “Scientific Writing”.
My program is focused on using an interdisciplinary research approach to better understand insect-microbe interactions during decomposition. 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. The knowledge gained through basic research allows further research avenues to be explored with more directed and applied research questions to solve real-world problems. For example, how insects can be used as alternative protein sources at a global scale, how insects can improve waste management practices, and the use of the human post-mortem microbiome for use in death investigations. Insects can solve many problems, and the work being performed in my lab strives to maximize the positive impacts insects can have to improve lives.
