Sarah Facey

I am an Entomologist with broad interests in community and global change ecology. My PhD looked at the effects of climatic and atmospheric change on invertebrate communities in Sydney, Australia. My undergraduate and Masters studies in my native England focused on insect ecology (predominantly Lepidoptera), including phenological responses to warming and population responses to agricultural land management practices. My work here at CSU has used protein-based mark-release-recapture techniques to track the movement of the Asian citrus psyllid pest (Diaphorina citri) at the landscape-scale, adding to the body of literature showing the movement of psyllids from low management areas towards areas of higher management intensity. Currently, I am interested in the role that the psyllid microbiome plays in the mediation of pesticide resistance.


Jason Corwin

I am a quantitative geneticist and systems biologist interested in plant-microbe interactions. My previous work during my PHD has focused on plant genetic control of central and specialized metabolism as well as the importance of genetic variation in the plant host and fungal necrotrophic pathogen in quantitative resistance. My undergraduate and Master’s work explored the use of biotechnology for restoration of American chestnut (Castanea dentata) to the eastern forests of North America after the introduction of the devastating chestnut blight fungus (Cryphonectria parasitica). At CSU, I am working to understand on how plant intra-specific variation shapes host-associated microbiomes and how plant hosts can shape the microbial communities that inhabit them.


Priyanka Mittapelly

I’m an Entomologist and molecular biologist with research interests in plant-insect and insect-microbe interactions. I received my Ph.D. from The Ohio State University supervised by Dr. Andy Michel. My work at Ohio State focused on ‘Molecular interactions of brown marmorated stink bug with its bacterial endosymbiont and their role in nutrient-provisioning’. My current work at CSU with Dr. Punya Nachappa will focus on understanding the mechanisms underlying insect-vector and plant-insect interactions and ways to manage plant pests and associated diseases.


Federico Martin

I’m a native from Santa Fe, Argentina and my educational background include an B.S. from Arizona State University and a Ph.D. from the University of Florida. My main area of interest is plant molecular biology and cell development focusing mostly in cereal crops. Currently, I’m working on an NSF funded project aimed to improve rice disease resistance response utilizing genome editing technology to analyze transcriptional activation of disease resistance QTLs.


Yuan Zeng

I am originally from China, and I came to U.S. for graduate school in Auburn University (Alabama) in Forestry, Entomology, and Statistics. I joined Dr. Amy Charkowski’s laboratory in Fall 2017 at Colorado State University, and my research in San Luis Valley Research Center focuses on improving detection and management of soil-borne potato pathogens, with an emphasis on Potato mop-top virus (PMTV), a virus causes necrosis of potato, and its vector Spongospora subterranea, the agent responsible for powdery scab on potato tubers in order to aid local farmers in understanding soil-borne potato pathogens and improving management strategies.

Kevin Lehner

I am a postdoc in John McKay’s lab. I study the complex interactions between genetics and environment in corn and sorghum. My goal is to identify genes that promote stable crop yields under drought stress. Originally from the hot and humid southeast, I am a proud graduate of Santa Fe Community College and the University of Florida. I received my PhD in Genetics and Genomics from Duke University in 2018.

Vijayata Singh

I am a molecular biologist, interested in plant signaling and disease resistance. I pursued my PhD from the National Institute of Technology in India and my work was focused on genetic regulation of systemic acquired resistance in Arabidopsis thaliana. My previous post-doctoral research in the University of Urbana-Champaign focused on plant receptor kinases involved in Brassinosteroid signaling.  At CSU, I am working with Dr. Vamsi J Nalam to understand how an alternative splicing event influences plants growth, development and disease resistance in soybean.
