He joined the Hoagland Lab as a graduate student in spring 2019 and completed his MS in December 2020. During his MS project, he investigated whether leaf mold compost could restore degraded soils and increase crop productivity in urban agricultural systems and increase survival of a beneficial microbe with antagonistic activity against tomato pathogens. He also conducted a survey of graduate students at Purdue University to identify barriers and opportunities to increase food access and nutrition via participation in urban ag gardens.

Lisseth obtained her BS in Agricultural Engineering from the University of Colombia-Bogota. During the final year of her BS degree, she conducted an internship in the Hoagland Lab, where she investigated how crop management practices could alter arbuscular mycorrhizal fungal communities and affect the potential for soybeans to tolerate water stress. After completing her degree, she returned to the Hoagland Lab as a graduate to follow up on this research, completed her MS in 2018.

Maria obtained her BS in Biology at the Antillean Adventist University in Puerto Rico. During her undergraduate studies, she conducted a research project evaluating the implications of unrestricted pesticide use on the health of local farm workers. Her interests in the health impacts of agricultural production led her to apply for a fellowship with the US-AID project, Cacao for Peace, which is aimed at supporting growth of the cacao industry in her native Colombia, by overcoming challenges associated with cadmium accumulation. She initiated her graduate studies in the Hoagland lab in 2018, and evaluating the potential for hyperspectral imaging to detect heavy metal uptake in plants, and completed her MS in 2020.

Matt obtained his BS in Microbiology and PhD in the interdisciplinary PULSe microbiology training program, both at Purdue University.
