JMartiny photo
Dr. Martiny received her B.S. in Ecology, Behavior, and Evolution at UC San Diego. She completed her Ph.D. in Biological Sciences at Stanford University, studying diversity patterns and conservation biology of birds, butterflies, and flies with Drs. Paul Ehrlich and Gretchen Daily. At some point, she became intrigued by the idea that most ecological theory ignored microorganisms, which make up the vast amount of biodiversity on the planet. She joined Dr. Brendan Bohannan’s lab as a postdoctoral researcher and then moved to Brown University, where she established her own lab. In 2006, she moved to UC Irvine, where she is a Professor in the Dept. of Ecology and Evolutionary Biology at UC Irvine. She is also the Director of the new UCI Microbiome Initiative.

Dr. Martiny is a fellow of the Ecological Society of America and the American Academy of Microbiology. She received several awards, including a CAREER award from NSF and a Gordon and Betty Moore Foundation Junior Investigator Award. Her work appears in both ecology and microbiology journals as well as in Science, Nature, and the Proceedings of the National Academy of Sciences.

Lab Staff

Claudia Weihe, Senior Technician and Lab Manager
Claudia has a Master’s degree in Genetics from the University of Greifswald in Germany. Previously, she worked at the Institute for Genetic Medicine at USC and the UCI School of Medicine until she joined the lab in 2007. She brings extensive experience in molecular microbiology and a sense of order to our lab. She is heavily involved in methods development in the lab as well as student training.

Visiting Scientists

Kazuo Isobe, Dept. of Applied Biological Sciences, University of Tokyo

Kazuo an Assistant Professor at University of Tokyo and is currently visiting the Allison and Martiny labs. He is interested in how microbial community dynamics alter biogeochemical cycling and influence the resilience and resistance of ecosystem functions. He completed his Ph.D. in Agricultural Sciences at University of Tokyo and studied ecological roles of N-cycling microbes in forests and agricultural fields.

2017 Lucia
Lucia Vivanco, University of Buenos Aires, Argentina
Lucia is a Research Scientist at IFEVA and is visiting to work on common projects involving microbial diversity and its role in litter decomposition.


Sydney Glassman, Postdoc
Sydney's research focuses on understanding patterns and processes governing microbial diversity, and their ecosystem functions such as terrestrial symbioses and decomposition.  As part of her dissertation research, she studied the effects of disturbances such as wildfires and invasive pathogens on ectomycorrhizal fungal communities. She received media attention for her research on ectomycorrhizal fungal recovery after the California Rim Fire, which was featured in the California Alumni magazine among other outlets. She received her B.A. in Biology at the University of Pennsylvania, where she also received a Masters of Environmental Studies. She completed her Ph.D. in Environmental Science, Policy, & Management at UC Berkeley with Prof. Tom Bruns. She will start her own lab at UC Riverside this summer!

Graduate students

Julio Avelar-Barragan, CMB PhD rotation student

Julio is working on microbial community characterization and analysis.

Alex Chase, PhD student
Alex is broadly interested in biogeographical patterns and how microbial populations shift in abundance over time. By utilizing both cultured isolates and metagenomic information, he is tracking how an abundant leaf litter bacterium, Curtobacterium, will respond across an elevational gradient.

Sarai Finks, PhD student
Sarai's research interests are horizontal gene transfer and niche differentiation in microbial communities.

Cynthia Rodriguez, PhD student
Cynthia is studying the assembly of microbial communities in the human gut, with a particular focus on the genus Bifidobacterium.

Kendra, website
Kendra Walters, PhD student
Kendra is interested in controls on the composition and function of microbial communities. Specifically, she is curious about how abiotic and biotic conditions impact communities and how changes in the environment might transform those impacts.

Recent departures

Michaeline Nelson Albright, PhD student
Michaeline is interested in the connection between microbial diversity and biogeochemical cycling. She is currently using metagenomics to investigate nitrogen cycling diversity in leaf litter bacteria.

Jonathan Abebe Independent research student. Jonathan conducted a research project on the variation in adsorption rates of different cyanophage strains using flow cytometry. Now a PhD student at Columbia University.

Alberto Lopez Independent research student. Now a PhD student at Northwestern University.

Richard Puxty, Postdoc
Rich is broadly interested in the functioning of photosynthesis in marine ecosystems. Through this he has stumbled into the field of cyanophages; viruses of cyanobacteria that are thought to modify aspects of photosynthesis for their own replication. In our lab, he is addressed the mechanisms and consequences of antagonistic co-evolution between these viruses and their hosts. He is currently a postdoc at University of Warwick with Prof. Dave Scanlan.

Jui-Ting (Tim) Tsai Independent research student.
