Dr. M. Soledad Benitez Ponce HeadshotDr. M. Soledad Benítez Ponce
Assistant Professor

Dr. Benítez Ponce is an Assistant Professor in the Department of Plant Pathology at The Ohio State University (OSU). At OSU, Dr. Benítez Ponce is developing a research program on soil and plant-associated microbial communities, with an emphasis on agricultural production systems. A key component of her research is studying microorganisms at the community level, therefore evaluating multiple microbial taxa and their potential interactions. The Benítez Ponce laboratory focuses on measures of diversity, composition, and function of the microbial community, and their impact on plant health and yield. The laboratory applies high throughput molecular techniques and bioinformatic approaches to characterize the diversity and function of microbial communities in plants and the environment in which they grow. They combine this with field and greenhouse experimentation, on-farm surveys, and single isolate characterization; and integrate our results through multivariate data analyses. Currently, they are working on cropping systems of social and economic relevance to Ohio, in particular corn and soybean production and leafy green hydroponics.

His program has been awarded grants from industry partners, national (NSF-NIFA Joint Plant Biotic Interaction Program; USDA SCRI; USDA FACT-CIN) and state (Ohio Department of Agriculture) funding sources and his trainees have received competitive fellowships (OSU University, FAES Environmental and Diversity, OSU Presidential [post- and predoctoral] and USDA-NIFA Pre- and Postdoctoral Fellowships) to carry out impactful agricultural research. The Emerging Infectious Disease Ecology team is a diverse, interdisciplinary group dedicated to advancing plant, microbial and agricultural science. 

Dr. Alex Lindsey HeadshotDr. Alex Lindsey
Associate professor

Dr. Lindsey is an Associate Professor of Crop Ecophysiology in the Department of Horticulture and Crop Science at The Ohio State University. Since joining the faculty in 2015, he has focused on how crops interact with environmental factors to influence growth and yield. He also teaches courses on crop production, plant physiology, and seed science and serves as coordinating advisor for the Agronomy specialization of the Sustainable Plant Systems major. Dr. Lindsey received his PhD in Agronomy from The Ohio State University in 2015 under Dr. Peter Thomison, and has been a Certified Crop Advisor since 2009. Prior to coming to Ohio, he received his BS and MS degrees from Michigan State University. 

Dr. Megan Meuti HeadshotDr. Megan Meuti
assistant professor

Dr. Meuti is an Assistant Professor in the Department of Entomology at The Ohio State University. Dr. Meuti earned her PhD in Entomology from The Ohio State University in 2014. After teaching at Kenyon College as a visiting professor for one year, she joined the faculty in her home department. Dr. Meuti’s research focuses on seasonal responses in the Northern house mosquito. This species transmits West Nile virus to humans and animals throughout North America during the summer and fall, but enters a hibernation-like state in the winter where they divert their resources from reproduction and to survival. Dr. Meuti’s laboratory is characterizing how mosquitoes measure seasonal changes in day length and translate this information into hormonal and biochemical pathways. Additionally, her lab is characterizing when mosquitoes initiate and terminate their overwintering dormancy in the field and how human-mediated changes to the environment, like light pollution and higher temperatures associated with urban heat islands, impact mosquito seasonal responses and disease transmission. Dr Meuti's research is supported by the National Science Foundation and the National Institutes of Health. In addition to her research, Dr. Meuti teaches Natural Science General Education courses as well as advanced graduate classes on insect physiology and molecular biology. Dr. Meuti also translates her research to broad audiences and uses insect education outreach to increase scientific literacy and public engagement. She has won awards for both teaching and research mentorship and continually strives to conduct the highest quality research and support her students and collaborators to achieve their personal and career goals.

Dr. Dominic Petrella HeadshotDr. Dominic Petrella
assistant professor

Dr. Petrella is an Assistant Professor at The Ohio State University Agricultural Technical Institute on the CFAES Wooster Campus. Dr. Petrella is the Program Coordinator for the Turfgrass Science Program, with a 70% teaching and 30% research appointment. The focus of the 2-year Associates of Applied Science Turfgrass Science Program is to provide hands on learning opportunities for students entering into turfgrass management careers, and Dominic is particularly interested in teaching these students more about data-driven management decisions that can save resources, time, and money. His primary research interests revolve around turfgrass response to environmental cues and stresses, with most attention paid to responses to light. Dominic is most interested in turfgrass perception and acclimation to alterations to spectral light quality due to foliar shade and using this information to select and breed for shade tolerant turfgrasses. Beyond shade, Dominic has been currently investigating the role of high-intensity light stress on cold tolerance and cold acclimation in a diverse range of turfgrass species and cultivars, funded by USDA and United States Golf Association grants.   

Dr. Mitchell Roth HeadshotDr. Mitchell Roth
assistant professor

Dr. Roth is an Assistant Professor in the Department of Plant Pathology at The Ohio State University. Dr. Roth grew up on a farm in rural Michigan, but it wasn’t until a research experience in college that he became interested in biological research related to agriculture. Dr. Roth earned his BS at Grand Valley State University, then went on to earn his Ph.D. at Michigan State University studying Genetics and Plant Pathology. Broadly, he is interested in when, where, and how organisms interact. When it comes to plants and pathogens interacting, a myriad of factors affect the outcome of that interaction. Research in the Roth lab focuses on the genetic components that influence the outcome of plant-microbe interactions by using a combination of “-omics”, forward, and reverse genetic approaches. They investigate the role of pathogen genes in virulence, and the role of plant genes in resistance or susceptibility, and aim to use this knowledge to genetically engineer crops with durable resistance to pathogens.

Dr. Jonathon Van Gray HeadshotDr. Jonathon Van Gray
assistant professor

Dr. Van Gray is an Assistant Professor at The Ohio State University Agricultural Technical Institute on the CFAES Wooster campus. He grew up spending far too much time enjoying riparian areas. His research focuses on the metagenomic dynamics of the stream microbiome under increasingly modified environmental conditions. Within this context, he has three general lines of inquiry: 1) How are human-induced landscape alterations within a watershed reflected in longitudinal patterns of microbial metagenome assembly? 2) What implications do compositional changes in the microbial community have on microbially-mediated ecosystem services and can this be exploited to predict overall ecosystem health? and 3) How can this information be leveraged to better manage and restore degraded aquatic resources? Current projects include assessing microbial response to freshwater salinization syndrome through a biogeographical lens, the characterization of wastewater effluent contributions to the antibiotic resistome of headwater stream communities, and how community coalescence at stream confluences is affected by upstream dispersal dynamics.
