Assistant Professor, PhD
Megan's translational research focuses on soilborne fungal pathogens that cause crop diseases. She is interested in improving disease management and environmental sustainability through considerations of pathogen biology, ecology, and epidemiology. Research questions include teasing apart the interaction of cover crops and soil health, inclusive of pathogens; predicting the impact of climate change and abiotic stress on disease development; integrating disease escape mechanisms and genetic resistance to improve soybean variety selection; harnessing the pathobiome for biological control; and understanding Sclerotinia sclerotiorum virulence factors through -omics approaches and gene silencing to better manage Sclerotinia stem rot.
Megan earned her PhD in Plant Pathology, with a minor in Plant Breeding from the University of Wisconsin, Madison; her MSc in International Agricultural Development from University of California, Davis; and a BA in Environmental Studies (with distinction) with a Biology minor from Hendrix College. She completed a USDA Postdoctoral Fellowship and the University of California, Davis and a USAID RIFA Fellowship at the University of Pretoria in South Africa.
Researchers
Kathleen Markham, Ph.D. (she/her)
Kat joined the lab in the Spring of 2023 as a researcher and is eager to get her hands dirty with soil-borne pathogens! She received her Ph.D. in Biochemistry from the University at Buffalo, where she used the mouse model to understand the role of integrin receptors in cell-cell/cell-matrix interactions. Her long-standing interest in plant biology led her to join the 2016 class of Frontiers and Techniques in Plant Science at Cold Spring Harbor Laboratory. She later pursued her postdoctoral studies at the University of Minnesota, where she sought to understand how the plant circadian clock mediates inter-tissue crosstalk in the Arabidopsis leaf using spatial transcriptomics. She is thrilled to be joining the McCaghey Lab in their important work and hopes her work here will impact Minnesota growers. Outside of lab, Kat enjoys singing, drawing (badly), and exploring Minnesota with her husband and little ones!
Alexis Shatrau Passolt, (she/her)
Alexis joined the lab in May 2025 while nearing the completion of her MS in Plant Pathology from the University of Minnesota. As Researcher II in the McCaghey lab, Alexis primarily assists in supporting the numerous field trials conducted by the laboratory during the summer months. Her research in the lab currently centers on investigating the utility of soil microbes isolated from agricultural or forested sites that may have potential biocontrol potential. In her MS work, she investigated the host range of C. gregata, a soilborne pathogen of soybean, as well as seed treatment efficacy against brown stem rot, the disease caused by C. gregata. In her free time, Alexis likes to play soccer, hike, and to bake.
Graduate Students
Hsuan-Fu Wang, MSc, (he/him)
Hsuan-Fu joined the lab as a Ph.D. student in the fall of 2022. His research is focused on characterizing aggressiveness determinants of Sclerotinia sclerotiorum using gene silencing strategies. As a master's student, he researched Fusarium spp. and worked to identify antifungal drugs to prevent tomato wilt and Panama disease. Outside of research, Hsuan Fu enjoys playing tennis and the flute, as well as painting.
Hunter Kluegel, BSc
Hunter joined the lab as an MS student in August of 2024 after graduating with a BS in Plant Science from the University of Minnesota. His research is focused on the impacts of cover crops on disease incidence and severity of Sclerotinia sclerotiorum and Rhizoctonia solani in soybean and dry bean systems. Before beginning his MS, he worked as a field technician in a Small Grains Pathology Lab that focused on screening nurseries to determine resistance to Fusarium Head Blight in barley, Bacterial Leaf Streak in wheat, and Smut in oats. Outside of his research, Hunter enjoys practicing hot yoga, singing, and exploring the local art scene of the Twin Cities.
Jasper Tao BSc, (she/they)
Jasper joined the lab in August of 2024 as a Master’s student and has transitioned to the PhD program. Graduating with a BS in Agricultural Plant & Soil Science from California State University Monterey Bay, she previously conducted research on oomycete and fungal soilborne pathogens of leafy greens, including impacts of anaerobic soil disinfestation and evaluating the potential of local Streptomyces isolates for pathogen inhibition and plant growth promotion. Jasper’s primary research in the McCaghey lab assesses impacts of deficit irrigation and nitrogen on Russet potato stem, foliar, and tuber diseases. Her second project is focused on biological control of Sclerotinia stem rot of canola, isolating sclerotia-inhabiting microbes and assessing their inhibitory modes of action. Jasper’s ultimate goal is to increase accessibility of plant pathology research in fruit and vegetable production.
