Overview

Timothy L. Friesen is affiliated with the United States Department of Agriculture in the United States. Their research primarily falls within the field of Agricultural and Biological Sciences, with a strong focus on Plant Science as evidenced by the volume of publications in the subfield.

Their work concentrates particularly on topics involving Wheat and Barley Genetics and Pathology, Plant Disease Resistance and Genetics, and Mycotoxins in Agriculture and Food. Additional areas of research include Plant Pathogens and Fungal Diseases, Plant-Microbe Interactions and Immunity, Plant pathogens and resistance mechanisms, and Genetic Mapping and Diversity in Plants and Animals.

Friesen has contributed to numerous publications, notably in venues such as bioRxiv (Cold Spring Harbor Laboratory) and Zenodo (CERN European Organization for Nuclear Research), each with 12 publications. Other frequent publication outlets include Theoretical and Applied Genetics (6 publications), Molecular Plant-Microbe Interactions (5 publications), and Phytopathology (5 publications).
