Using a combination of field observations and experiments, I investigate how population processes, abiotic conditions and community context determine net effects of the interactions for the fitness of each participant species. Specific conceptual areas of interest include: (1) conflicts of interest between mutualists and their consequences for the maintenance of beneficial outcomes in these interactions and (2) context-dependent outcomes in both mutualisms and antagonisms. I am also collaborating on theoretical and empirical investigation of (i) the fragility of mutualisms in light of conservation threats and mechanisms of restoring disrupted interactions and (ii) the causes and consequences of “cheating” within mutualism.
My main questions involve how Sky Island native bees might respond to warming temperatures. Desert carpenter bees are common in the Southwest, but we don’t know how climate change will affect them. My goal is to understand the impacts of projected temperature increases on carpenter bees by finding their thermal tolerances and determining where they will be able to live in warmer future conditions. I enjoy sharing my love of science through K-12 and public outreach. I am currently an instructor for UA’s Sky School, and I TA undergraduate courses at UA. I also enjoy drawing, hiking, and camping with my dogs.
I am a first-year PhD student who is broadly interested in context-dependency in species interactions, and in how antagonistic and mutualistic pairwise interactions interact with each other and shape the traits of the interacting species. I received a B.A. in Biology from Amherst College in 2017, where I studied disease resistance in multi-pathogen systems. I then spent the 2017-2018 academic year on a Fulbright Research Grant at Lund University in Sweden researching the energetic costs of floral fragrance production, and how floral fragrance is affected by abiotic factors. When I’m not in the lab or the field, I enjoy playing in the UA Wind Ensemble and hiking.
I am interested in mutualistic interactions, specifically seed dispersal mutualisms and their broader impacts on species’ populations and communities. There are many desert systems, including ant dispersal of Datura seeds and the interaction between mutualists of desert mistletoe, that I am excited to explore. Furthermore, I am passionate about making the sciences an inclusive environment for LGBTQ students and increasing queer visibility within STEM fields.
Broadly, I am interested in examining the causes and consequences of multi-species interactions as they relate to community and network ecology. To that extent, I am investigating the cochineal (Hemiptera: Dactylopius spp.) – Opuntia spp. (Cactaceae) system and its community assemblage over time and space with a particular focus in urban landscapes. Additionally, I am an instructor for UA’s Sky School <http://skyschool.arizona.edu> with a strong background in science education with/for underserved students and learners in the U.S. and Latin America.
