Biography

Soon Li Teh began his appointment as an Assistant Professor in October 2023. He received his B.Sc. In Agronomy and Biochemistry from the University of Wisconsin-Madison. In 2018, he completed his PhD in Plant Breeding and Molecular Genetics at the University of Minnesota. His work integrated genomics and metabolomics in characterizing genetic and biochemical resistance to grape powdery mildew. After graduation, he joined Washington State University as a postdoctoral researcher, and subsequently, as a research assistant professor. Over the past five years, he led the WSU pear rootstock breeding program to breed size-controlling Pyrus rootstocks. In his current role, Dr. Teh will focus on developing high quality cold-hardy wine and table grapes to benefit growers in Minnesota and the broader cold-climate regions.

Teaching

HORT 1031: Vines and Wines (Fall semester)

Research

My research program focuses on integrating conventional and molecular plant breeding approaches to develop improved wine and table grape cultivars for cold climate production. Breeding targets include cold hardiness, resistance to various diseases and pests, as well as desirable fruit quality/biochemistry. My research aims to characterize genetic determinants of these breeding targets for development of diagnostic DNA markers to guide breeding decisions.

Outreach

Coordinated Extension activities with Madeline Wimmer (Extension educator) and Andrew Horton (enology specialist) to benefit grape growers, winemakers and producers in Minnesota. Activities include workshops, training, conferences, and educational programs.
