معرفی
David M. Geiser is a Professor in the Department of Plant Pathology and Environmental Microbiology at Pennsylvania State University, where he conducts research in molecular evolutionary genetics and systematics of fungi. His work focuses on the phylogenetics and taxonomy of Fusarium and related plant pathogens, with implications for agriculture and food safety.
His research interests include molecular phylogenetics, species complex delineation, DNA sequencing, fungal genomics, and mycotoxin production. He is a leading expert in the taxonomy and identification of Fusarium, contributing to major resources such as FUSARIUM-ID. His work integrates genomic, phylogenetic, and morphological data to resolve fungal species boundaries and improve diagnostic accuracy.
The recent publications show a strong trend in phylogenomics, fungal taxonomy, and molecular diagnostics, particularly within the Fusarium genus. His research spans species discovery, misidentification issues in culture collections, trichothecene potential, and the development of genomic tools for pathogen identification. These works reflect a deep engagement with both fundamental fungal systematics and applied plant pathology.
- Elected to leadership in the Mycological Society of America
Dr. Geiser has supervised and collaborated with numerous researchers, including PhD students and postdoctoral scholars, though formal advisees are not explicitly listed. He has been involved in multiple collaborative grants focused on fungal genomics, taxonomy, and plant disease diagnostics. His laboratory is part of a broad network of fungal researchers and contributes to international efforts in fungal nomenclature and classification.
His lab is involved in high-impact collaborative research, particularly in the areas of fungal phylogenomics and diagnostic tool development. He is part of a global consortium working on fungal taxonomy and sequence-based nomenclature, contributing to standards that shape modern mycology.
