Excited to be part of this collaboration with the Burrows lab exploring twitching and surface surface sensing by P. aeruginosa. This work further delineates a role for the T4P motor proteins and pili for surface sensing.

Please repost -- The Univ. California Davis dept of Plant Pathology is hiring a Fungal biologist / Mycologist

Applications due Dec 1

Application portal: recruit.ucdavis.edu/JPF07339

Screenshot shows part of the job posting (with alt-text of the same text)

he Department of Plant Pathology at the University of California, Davis is seeking applications for a fulltime, tenure-track Assistant Professor position in Mycology, with a focus on plant pathogenic, symbiotic,
or mycotoxigenic fungi and fungal-like organisms (e.g., oomycetes). We are looking for a highly
motivated and creative scientist with a strong background in mycology and/or the biology of fungi and
fungal-like organisms that interact with plants. The successful candidate will be expected to develop a
world-class, externally funded research program that integrates both fundamental and applied aspects
of fungal biology within the context of plant pathology. We welcome applicants pursuing a wide range
of research topics related to plant-associated fungi, including but not limited to mechanisms of fungal
pathogenesis or symbiosis with plants, population genomics and evolution of fungal plant pathogens,
plant-associated fungal microbiomes and plant-microbe interactions, and/or one health approaches to
fungal diseases and antifungal resistance. Applicants working in other relevant research areas involving
pathogenic, symbiotic, or mycotoxigenic fungi or fungal-like organisms that affect plant health are also
encouraged to apply. The successful candidate will have significant opportunities for collaboration with
faculty in plant pathology, microbiology, genomics, and agricultural sciences, and to contribute to
addressing issues of importance to California’s agricultural and natural ecosystems.
The appointee primary teaching responsibilities will be teaching Introductory Mycology, an upperdivision lab class, and SAS 30, Mushroom, Molds & Society, a general education class for non-majors.
Additional graduate and undergraduate teaching responsibilities may be assigned based on
departmental needs and the candidate’s expertise. The department offers modern instructional
facilities, including a newly renovated teaching laboratory.
