Biography:

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.

Other academic affiliations

Faculty member of the discovery theme Sustainable & Resilient Economy (http://sre.osu.edu)
Member of Center for Applied Plant Sciences (http://caps.osu.edu/)

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.

Major Projects

Domestication and characterization of Taraxacum kok-saghyz as a novel source of rubber
Germplasm development and genetic characterization of biomaterial-related traits in outcrossing crops.
Centromere manipulation for germplasm development of outcrossing crops.
Ageing in perennial crops.

Current graduate advisees

Katherine D’Amico – joined the lab in 2017, addressing the role of epigenetics in the ageing outcrossing perennial crops using almond and the bud-failure disorder as a model. Ph.D. expected in 2020.

Matthew Willman – joined the lab in 2017, working on the genetic characterization of pomological and biochemical traits of black raspberry (Rubus occidentalis). M.Sc. expected in 2019.
