Jan E. Leach is the Associate Dean for Research in the College of Agriculture, University Distinguished Professor at Colorado State University and an Adjunct Scientist at the International Rice Research Institute (Philippines). She is an authority on the molecular biology of plant– pathogen interactions. Her research focuses on understanding the molecular basis of durable disease resistance, particularly in rice-pathogen interactions. Other projects currently underway in her laboratory are related to understanding the impacts of increasing temperatures associated with a changing climate on plant disease and resistance, microbiome-insect-plant interactions, the development of novel tools for detection and monitoring of microbes associated with plants, and bioenergy (genetics of biomass production). She is a Fellow and past President of the American Phytopathological Society (APS). She is past chair of the APS Public Policy Board and led the initiation of the Phytobiomes Initiative. Dr. Leach is also a Fellow of the American Association for the Advancement of Science (AAAS). She served as Chair of the AAAS Section O (Agriculture, Food, and Renewable Resources) in 2007, and as a member of the Section O Steering Committee. Dr. Leach is a Fellow of the American Academy of Microbiology and serves on the National Science Advisory Board for Biosecurity. Prior to her appointment at CSU, Dr. Leach was named a University Distinguished Professor at Kansas State University in 1998. She served as President of the International Society of Molecular Plant–Microbe Interactions and has served on or chaired advisory committees for a number of national and international projects, programs and institutions, including the U.S. Rice Genome Sequencing Project, the Research Core for Interdisciplinary Science (RCIS) at Okayama University (Japan), Rural Development Agency (Korea), and a National Research Council (NRC) study. She has served on numerous editorial boards, and was Editor in Chief of the APS journal Molecular Plant-Microbe Interactions. Leach earned her B.S. and M.S. in Microbiology from the University of Nebraska-Lincoln, and her Ph.D. in Plant Pathology from the University of Wisconsin-Madison. She was a postdoctoral fellow at East Malling Research Station in Kent, England. Follow her on Twitter @PhytoBiomes @JanPhytoBiomes
Emily received a B.S. in Horticulture and M.S. in Entomology at Colorado State University. Currently, her research focuses on understanding the complex multi-trophic interactions in the wheat phytobiome with a focus on: wheat, Russian wheat aphid, and their associated bacteria.
Post Doctoral Fellows
I graduated with a BS in Molecular Biology and Biotechnology from Arizona State University and received my PhD from the Plant Molecular and Cellular Biology program at the University of Florida in 2012. My project involved the mapping and characterization of maize seed mutants with the aim to understand the molecular mechanisms of seed and plant development, particularly at the transcriptional and post-transcriptional level. I have held post-doctoral positions at the University of Florida as well as Colorado State University working in different aspects of post-transcriptional mechanism of gene regulation that are involved in plant development and adaptation to different environmental conditions. Building on my past experiences and looking forward to continue implementing molecular biology to understand plant adaptation, I decided to join the Leach Lab where I am currently working on a NSF funded genome editing project aimed to improve defense responses of diverse rice cultivars to invading pathogens.
Dr. Jonathan M. Jacobs joined the Leach laboratory in Spring 2017 funded by a USDA NIFA Postdoctoral Fellowship. This grant provides Dr. Jacobs two years of funding to study the evolutionary and biological basis of vascular diseases by Xanthomonas pathogens of cereal crops. Dr. Jacobs is returning stateside after a postdoc in France and Belgium funded by an NSF Postdoctoral Fellowship in Biology and a Fulbright Scholar Award. His research explores the biological and molecular aspects of the natural infection process of agriculturally important plant pathogenic bacteria. He focuses on plant disease problems faced by tropical farmers in hopes to provide research-based solutions for better disease management. Dr. Jacobs is enthusiastic about student mentorship and developing tools to enhance undergraduate teaching to allow students to the understand natural world.
Jia (John) Long
I am originally from Bogota, Colombia. Currently, I am a Ph.D. student in Plant Pathology in the Bioagricultural Sciences and Pest Management Department. I did my bachelor’s degree in biology at the Universidad Nacional de Colombia. During my undergraduate studies, I became interested in studying molecular plant-microbe interactions. Therefore, I joined the Molecular Plant Pathology research group for one year, under the advisement of Dr. Camilo López.
Afterwards, I worked as a research assistant at the International Center for Tropical Agriculture (CIAT) in the Biotechnology Research Unit, for more than 2 years. As part of the project, I was a visiting scholar at Dr. Dellaporta’s Lab at Yale University on two occasions.
My research project is aimed at finding novel resistance sources for bacterial diseases of rice in Africa and Latin America. It is a collaborative project between CSU, the International Rice Research Institute (IRRI) in the Philippines and CIAT in Colombia. My main goal is to contribute to the reduction of losses caused by pathogens in crops, which will help decrease poverty and malnutrition in developing countries. On my return to Colombia, I plan to transfer the knowledge acquired abroad, consolidate research on sustainable crop development, and strengthen the collaborative research in different countries.
Dr. Jillian M. Lang
Jillian is a Leach Lab alumna. She currently serves the College of Agricultural Sciences as Director of Strategic Partnerships but continues to conduct small scale research in the Leach Lab. She is interested in the evolution of pathogenicity in Xanthomonas species and has expertise in the development of molecular diagnostic tools for important and emerging plant pathogens. Her favorite agricultural systems are rice and corn. She has a B.S. in Biology from the State University of New York, College at Fredonia, then received her M.S. in Plant Pathology and a PhD in Cell and Molecular Biology at Colorado State University.
