Jonathan Fresnedo Ramirez, Ph.D. earned his B.S. in Agronomy and Plant Production from Universidad Autónoma Chapingo in Mexico. Subsequently, he earned his Ph.D. at the University of California at Davis working on the implementation of genomics and Bayesian statistics in the genetic improvement of perennial fruits such as peach and almond. In the Institute of Biotechnology at Cornell University, he was a Postdoctoral Associate working with genomics and breeding of grapevine and related species in the genus Vitis. In August 2016, Jonathan joined the Department of Horticulture and Crop Science at The Ohio State University, established at the Ohio Agricultural and Development Center (OARDC) on the Wooster campus.

The Fresnedo lab:
Jonathan is interested in the use and implementation of genomics for efficient germplasm improvement of outcrossing species and domestication of new crops. Trait targets include the production of biomaterials. The research pursued by graduate students, visiting researchers and staff in Jonathan’s lab is expected to deliver results and technologies relevant for outbreeding species considering translational and applied perspectives. The outcomes from this research will also be developed in a perspective of a sustainable and resilient economy.
- Genomic characterization of aging and its effect in perennial crops with emphasis in almond
- Domestication and characterization of Taraxacum kok-saghyz as a novel source of natural rubber
- Integration of genomics and metabolomics for the improvement of apple (collaboration with the Cooperstone lab: https://phytochemicals.osu.edu and Dr. Diane Miller: https://hcs.osu.edu/our-people/dr-diane-miller)
Current graduate advisees
- Daniel Williams – joined the lab in 2019, his project address issues on the domestication and genetic characterization of Taraxacum kok-saghyz. Ph.D. expected in 2023.
- Camila Gutierrez Manriquez – joined the lab in 2021, her project aims the development of molecular markers for self-compatibility in Taraxacum kok-saghyz. M. Sc. expected in 2023.
Former graduate advises
- Matthew Willman – 2017-2019, earned a M. Sc. working on the genetic characterization of black raspberry (Rubus occidentalis) to enhance its breeding.
- Katherine D’Amico –2017-2020, earned a Ph.D. addressing the role of epigenetics in the ageing outcrossing perennial crops using almond and the bud-failure disorder as a model. Katie received an USDA NIFA AFRI Predoctoral Fellowship in 2018.
