Research Interests

Whenever I attend a scientific talk or read a paper, my question is always this: WHAT ABOUT THE FUNGI? So if you are looking to address this question in your own research, let me know!

Exploring the unknown, overlooked, and marginalized

​I investigate large questions in ecology and evolution using fungi as my study system. I am interested in drivers of patterns of diversity along environmental gradients, including latitudinal and elevational gradients, as well as moisture gradients across an alpine tundra. I am interested in the role of biotic interactions in driving these patterns of biodiversity.
 
Within these biotic interactions, I focus on the symbiosis continuum. 
 
I am fascinated by and drawn to the often overlooked, underappreciated, and yet integral critters of the world around us – lichens, fungi, slime molds. This fascination extends beyond my study organisms to ants, bryophytes, collembolans, mites, algae, tardigrades, and even to often-overlooked micronutrients such as sodium*.

Current Research

I am currently the Tucker Curator of Lichenology at the University & Jepson Herbaria, University of California Berkeley. 

Here I am establishing my own research program, which includes investigating the ecology and evolution of tidal lichens, a natural history survey of the California lichen flora/funga, and expanding upon my research on the molecular basis of the lichen symbiosis.

I am keen to form collaborations with artists, and other members of the community! If you are interested in learning more about what we do with the lichen collections, please contact me: lichen_curator[at]berkeley.edu

Long Term Research

One of my ongoing projects is a collaboration with Diane Ebert-May and the Niwot Ridge LTER (Long Term Ecological Research) site, monitoring lichen and vascular plant community dynamics in 30 permanently marked plots. As of right now, this is a 50 year dataset!

I am a proponent of long term ecological and evolutionary studies (the Beal seed viability experiment, the Lenski bacterial evolution experiment, the Grants’ study of the Galapagos finches, to name a few), with the understanding that, even if one were to establish a study in graduate school and run it into their 90’s, that would still serve as a mere blip from a geological or evolutionary perspective. If we are really to understand how the world works, we must begin to think on its scale. When I study lichens, I like to imagine living small and living slow. How would that change how I sense and react to the world?
