Joshua Kellogg

Joshua Kellogg is an Assistant Professor at Penn State University in the Department of Veterinary and Biomedical Sciences, with affiliations to the Penn State Cancer Institute, Huck Institutes of the Life Sciences, One Health Microbiome Center, and Center for Cannabis and Natural Product Pharmaceuticals (CCNPP). His research focuses on metabolomics, natural product pharmacology, and ethnobotanical analysis.

• Key Research Areas: Natural product chemistry, botanical safety assessment, mass spectrometry applications, and antimicrobial studies.
• Active Grants: Dietary phytochemicals for GI disease modulation (NIFA, 2023-2027); Artemisia-based SARS-CoV-2 therapies (NIAID, 2022-2023); Botanical mixture efficacy (NCCIH, 2018-2019).

Kellogg’s work spans metabolomics (untargeted profiling, biochemometrics), botanical drug research (LEAFBot spectral library), and environmental interactions (nutrient dynamics in aquatic ecosystems). Recent studies include predictive modeling for herbal product authentication, digital ethnobotany of Monotropa uniflora, and cannabis sativa quality control.
