University Plant Pathologist
Research scientist on the front line of potato disease
I can give you the genotype, the fungicide sensitivity, and the field history. What I can't do is promise next year looks like this year.
Faculty researcher at a land-grant or USDA ARS lab working on potato pathogens — Phytophthora infestans (late blight), Potato Virus Y and the other seed-borne viruses (PLRV, PVA, PVS, PVX), Streptomyces scabies (common scab), Spongospora subterranea (powdery scab), Pectobacterium and Dickeya (blackleg/soft rot), Verticillium wilt, Rhizoctonia, the Globodera nematodes (pale and golden cyst), and Meloidogyne (root-knot). Runs a lab with grad students and postdocs, designs field and greenhouse trials, sequences pathogen populations, publishes in Phytopathology and Plant Disease, advises growers through extension co-appointment or collaboration, and chases USDA NIFA SCRI, AFRI, and APHIS Farm Bill Section 7721 dollars.
USDA ARS labs at Beltsville MD, Prosser WA, Aberdeen ID, East Grand Forks MN, Orono ME. University programs at Cornell (Smart, late blight), NDSU (Gudmestad lineage on PVY), WSU (potato virology and Verticillium), U of Idaho (Aberdeen and Parma), U of Maine (Hao, late blight and powdery scab), Michigan State, Wisconsin (Hancock), Penn State, North Carolina State (sweet potato cross-listed). USABlight network ties the late-blight community together nationally.
Pathogen populations evolve faster than grant cycles fund the work — a new PVY strain or a fungicide-resistant late blight genotype appears mid-season and the next grant submission isn't due until January. Industry funders want a recommended cultivar or fungicide program; the data shows trade-offs and population variability. Reviewer 2 wants more replicates. Grad student funding contingent on the next SCRI award. Open-access publication fees out of dwindling indirect cost returns.
Mapping a resistance gene that breeders can stack into a commercial cultivar. Confirming a new late blight genotype via the USABlight network before it spreads to a clean region. A grad student first-author paper accepted in Phytopathology. A SCRI award funded that supports four years of population genetics. Cooperators at the research station hosting a successful field day on integrated disease management.
qPCR (TaqMan and SYBR), Illumina or Nanopore sequencing for pathogen population work, R and Python for statistical analysis and bioinformatics, GenBank and NCBI BLAST, EPPO Global Database for regulated pests, USABlight reporting, growth chambers and headhouse greenhouses, replicated field plots at the university research station, late blight DSS / BliteCast modeling, NIFA REEport, ORCID, the standard manuscript pipeline (LaTeX or Word, Phytopathology submission portal).
Field season May-October — trial planting, in-season ratings, harvest sampling. Lab and molecular work year-round but intensified November-April. Grant writing peaks December-February (SCRI, AFRI, APHIS 7721 deadlines). APS national meeting in summer (late July / early August), Potato Association of America meeting in August, regional grower winter conferences December-February. Manuscript writing on stolen evenings.
Career path
PhD in plant pathology — Cornell, NDSU, WSU, U of Wisconsin-Madison, Michigan State, NC State, U of Idaho are the dominant pipelines for potato pathology. Postdoc usually required (2-5 years), often at a USDA ARS lab or in another faculty member's program. Tenure-track faculty searches are narrow and infrequent; APS (American Phytopathological Society) job board is the central listing. Industry research roles at processors or seed companies are alternative landing spots for the same training.
Tenure-track salary on the university's faculty scale with grant overhead share, summer salary from external awards, and occasional industry-funded endowed-chair supplements. USDA ARS scientists on the GS scale (typically GS-13 to GS-15) with federal benefits and stable funding but less salary upside. Modest by biotech industry standards; the trade is intellectual freedom, lab ownership, and tenure.
