The Basu lab focuses on multiple research areas:
- Biological control for honey bee varroa mites
- Molecular ecology
- Disease ecology
- Sustainable pest and pathogen management
Metarhizium is a sporulating soil fungus. The Basu lab studies the effects of these microbial biopesticides for varroa mite control and aims to discover new strains of Metarhizium that can be more effective and tolerant to warmer temperatures. This labs primary goal is to produce new and effective strategies for beekeepers to use, in Washington and globally. There is also interest in investigating how these microbial biopesticides can be used to control other potential plant pests to boost agroeconomy.
Molecular, biochemical, and ecological tools are utilized to study various aspects of complex species to community interactions. Previous research findings have shown that beneficial soil mutualistic microbes improve plant responses to both pathogens and pests by enhancing plant defense chemistry and nutritional quality (Basu et al. 2021, Functional Ecology; Basu et al. 2022, Basic and Applied Ecology).
Values and Philosophy
Basu Lab aims to manifest a highly collaborative environment and show mutual respect by being highly committed toward promotion of DEI principles and gender equality.
Basu lab is committed to performing excellent, original, and quality research.
