My research aims to understand the unique association of obligate endosymbionts (“gut fungi”), which can be found worldwide, attached variously to the digestive tract of their (non-predaceous) arthropod hosts. This group of fungi, traditionally placed in the Class Trichomycetes, is quite understudied—historically having been studied by only a handful of researchers at any given time in the approximate century and a half since their first discovery. The gut fungi are diverse and most surveys where we have sampled in the last 10 years (particularly for members of the order Harpellales) have revealed new taxa (as high as 1 new species per 2-3 days with 1-3 people collecting and dissecting).
My fascination is truly captured by the biology of this group of symbiotic fungi and the surprising evolutionary twists that they present when you take a closer look at them. As I arrive in Idaho (never before surveyed for gut fungi) I am particularly interested in learning more about suitable and interesting moist habitats (springs, seeps, creeks etc.) where hosts might be expected (or even well studied) to begin to assess the western species of gut fungi that will be found here.
Therefore, as I initiate a research program at Boise State there will be opportunities for basic field studies (collections of aquatic insects and other suitable arthropods from local streams, creeks etc.), training in the techniques involved in dissecting hosts, proper slide preparation and using traditional morphological approaches to identify and initiate a species list of gut fungi in Boise and the vicinity. These techniques will require patience (all of the fungi are microscopic) to develop a steady hand and to acquire “an eye” and “search image” for them. If you believe you have such an interest, I will be delighted to speak with you about possible research opportunities in my lab.
Aside from biodiversity surveys to try to discover and document new species or expand known distributions of other species—using morphology, I also use molecular systematic tools and phylogeny reconstruction to infer natural relationships among extant taxa of gut fungi and to understand how they have evolved with their hosts (the fungi exhibit varying degrees of host specificity). The data being generated from DNA sequences, especially from unculturable exemplars of the dissected microfungi, are prompting us to pause and reconsider the origins of these symbionts that have evolved so intimately with their hosts. If you think graduate studies along this molecular systematic line would be of interest, please contact me.

Over 250 samples of gut fungi (Harpellales) were preserved for DNA extraction and sequencing (in progress). After a second survey, August 17 – September 2, 2002, based at Lake Snaasavatnet Field Station (operated by University of Trondheim), our taxonomic findings (9 new species) were consolidated and have been published as the first major survey of Norwegian Harpellales (Trichomycetes).
Led the first two expeditions to survey gut fungi in Mexico [with Laia Guardia Valle (Spain) and Matias Cafaro (Puerto Rico)]. 1st survey was based in Xalapa (at Instituto de Biologia et Ecologia) Nov. 3-19, 2005, included training one Mexican graduate student (Ricardo Garcia-Sandoval). The 2nd survey was based at Los Tuxtlas Field Station (UNAM) July 21-August 13, 2006. New species (both Harpellales and Asellariales) for at least two joint papers in preparation.
