Hi! I'm Chase.

I like fungi, teaching about fungi, and learning how fungi evolve to interact with other organisms.

I support the teaching, pedagogical development, and lab components of three fungus-filled courses in the Cornell School of Integrative Plant Science:

  • Biology and Management of Plant Diseases (PLPPM 3010/5010) with Prof. Kerik Cox

  • Mycology (PLPPM 4490) with Prof. Teresa Pawlowska

  • Magical Mushrooms, Mischievous Molds (PLSCI 2010/2013) with Prof. Kathie Hodge.

Students with questions about classes should check the relevant Canvas homepages for information, or contact me at the email address above.


I research how fungi evolve over time to work with, and sometimes against, other organisms. This includes studies on fungal diversity, evolution, symbiosis, and systematics. My study systems have included:

  • Fungus-farming ambrosia beetles, their fungus pockets (mycangia), and coevolution with their fungal crops (ambrosia fungi).

  • Discovery and description of new ambrosia fungus species.

  • Genomics and population genetics of the pathogens that cause Rapid 'Ōhi'a Death (Ceratocystis lukuohia and Ceratocystis huliohia).

  • Broader studies on fungi in the family Ceratocystidaceae and other fungi that live in wood with insects.

  • Coevolution and host-symbiont patterns between arbuscular mycorrhizal fungi (AMF) and other Mucoromycetes and their endohyphal bacteria (Candidatus Glomeribacter and Candidatus Moeniiplasma).

Thanks for visiting!
