Former Lab Members

Grads, Postdocs, Staff

Laura Bogar (Grad)

img_3294Laura joined the lab as a graduate student in September of 2013. She earned her undergraduate degree in Biology at Lewis & Clark College in May 2012. Laura’s research is focused on the ectomycorrhizal symbiosis between land plants and soil fungi. This relationship, in which plants trade fixed carbon (sugars) to the fungi in exchange for soil resources like nitrogen, has arisen dozens of times independently in the fungal lineages, and is critical for the nutrition of many temperate forest trees. She is interested in how this interaction functions on a physiological and genetic level, particularly with respect to compatibility between diverse plants and fungi, and how variation in symbiotic function across fungal lineages and environmental conditions contributes to the stability of the interaction over evolutionary time.

Max Segnitz (Grad)

IMG_2341Max joined the lab in 2013. He completed a B.A. at Berkeley in 2009 in Integrative Biology and Studio Art, and has since contributed to a number of research projects in various fields including plant ecophysiology, community ecology, and evolutionary ecology, conducting work in California, Panama, and Trinidad and Tobago. His interests begin broadly with large scale patterns in plant community structure across our planet’s tropical regions, but get narrower with an interest the role/mechanisms of plant-soil-feedbacks in shaping tropical forest composition & function. He has particular interest in how differences among soil fungal communities may contribute to contrasts in plant community dynamics across tropical regions.

Sonya Erlandson (Grad)

Sonya joined the lab in September 2011 as a graduate student in Plant Pathology at the U of M and joined the Stanford Biology Department with us. She completed her undergraduate degree in Biology & English at St. Olaf college. She has worked on a wide range of forest ecology projects in Sweden and for the USDA Forest Service. Sonya’s PhD. research characterized the reciprocal feedback between mycorrhizal community struture and plant ecophysiology across a strong hydrological gradient at the Cedar Creek Ecosystem Reserve. She collaborated with Prof. Jeannine Cavender-Bares, Jessica Savage, and Xiojing Sun at U of M who have carried out detailed ecophysiological characterization of Salix spp. at this site.

Marie Duhamel (Postdoc)

IMG_5763Marie joined the lab as a postdoc in August 2014. She completed her PhD in the summer of 2013 at the University of Rennes 1 (FR) and the Free University of Amsterdam, where she worked respectively with Philippe Vandenkoornhuyse and Toby Kiers. She is interested in long lasting interactions among (micro)organisms from both functional and evolutionary perspectives, and particularly in how plant and microbial symbionts are linked and interact with each other, the strategy they use to benefit most from the association and the consequences of these interactions on ecosystem functioning. At Stanford she worked on large-scale patterns of taxonomic, functional and genetic diversity of soil fungal communities and their links to plant community dynamics and ecosystem function.

Nora Dunkirk (Tech)

IMG_9775Nora started as our lab technician in Summer 2014 after earning her B.S. in Ecology and Evolutionary Biology from the University of Tennessee Knoxville, where she worked with Dr. Aimee Classen studying how litter community composition affects decomposition rate in old fields. In the Peay Lab, Nora worked on next generation sequencing projects such as the Dimensions of Biodiversity project and the Tule Elk project in Point Reyes. She worked closely with the JGI to sequence the genomes/transcriptomes and community metagenomes/metatranscriptomes of key dung fungi. Nora’s research interests include plant–fungal interactions and evolutionary connections between functionally different fungi. Nora graduated from the Peay Lab in 2016 and is currently working towards her Ph.D. as a member of Dr. Anne Pringle’s group at the University of Wisconsin.

Alison began her PhD at Stanford in September 2010 and joined our lab in December
DSC_02242012. She received a B.A. in Organismic and Evolutionary Biology at Harvard University, where she conducted her thesis research on acoustic niche partitioning. She then worked as a field assistant for a year in the Peruvian rainforest studying an ant-plant symbiosis. Alison’s PhD work, which was coadvised by Dr. Carol Boggs, focused on interactions between the gut flora and their host. Taking a nutritional perspective, her dissertation addressed the interplay between host nutritional ecology and gut bacterial symbioses in butterflies. Alison received her PhD in June 2016. Currently, she is a postdoctoral fellow at the University of Arizona, where she is studying insect–microbial symbiosis in Dr. Molly Hunter’s laboratory.

Michelle Berry (Grad)


Michelle began her master’s degree in Earth Systems in September 2012 and joined our lab in the spring of 2013. She completed a B.A. in Human Biology also at Stanford where she focused on the neural basis of animal behavior. As an undergrad, she participated in elephant behavioral research in Namibia. As a grad student, she moved on to smaller organisms, exploring interactions between Neotropical butterflies and their gut microbes in collaboration with Alison Ravenscraft. Michelle’s thesis, co-advised by Dr. Carol Boggs, examinesdthe role that host phylogeny plays in structuring gut communities and tests the hypothesis that the gut community has coevolved with its host. Michelle is currently a Ph.D. student at the University of Washington Department of Genome Sciences.

Jenny joined the lab as a postdoc in September 2011. She completed her PhD in the Spring of 2011 at UC Irvine, where she worked with Kathleen Treseder. Jenny is a chemical ecologist interested in understanding the fine-scale mechanisms that give rise to large-scale ecosystem processes. Her research is centered on the mechanisms that structurepatterns of organic matter decomposition, the role of plant-microbial mutualisms in ecosystem-level carbon and nutrient cycling and terrestrial feedbacks to global change. Jenny joined the faculty at Boston University as Assistant Professor in Biology in September 2014. Her laboratory at Boston University studies the ecology, chemistry, and biology of microbes using biochemical and next-generation sequencing analyses.
