Anna Michalak Department of Global EcologyCarnegie Institution for Science260 Panama St.Stanford, CA firstname.lastname@example.orgBio C.V. Lab TabsOur ResearchOur research focuses primarily on two areas. We are interested in understanding the cycling and emissions of greenhouse gases at the Earth surface at urban to global scales – scales directly relevant to informing climate and policy – primarily through the use of atmospheric observations that provide the clearest constraints at these critical scales. We are also interested in climate change impacts on freshwater and coastal water quality via influences on nutrient delivery to, and on conditions within, water bodies. Our approach is highly data-driven, with a common methodological thread being the development and application of spatiotemporal statistical data fusion methods for optimizing the use of limited in situ and remote sensing environmental data.

In particular, he is interested in developing robust statistical models for estimating climate impacts 1) on large-scale nitrogen runoff, 2) on historical river temperature regimes, and 3) on the increasing likelihood of extreme river temperatures into the future. Tristan is currently a 4th year PhD student in the Department of Earth System Science at Stanford University. Mae Qiu (Scientific Programmer) Nina Randazzo (Graduate Student)Nina is a Stanford PhD candidate who researches carbon dioxide exchange between the atmosphere and terrestrial biosphere. She is particularly interested in how climatological and meteorological systems influence biospheric carbon balance. Yoichi Shiga (Postdoctoral Associate)Yoichi's work explores carbon cycle dynamics at regional to continental scales focusing on improving our understanding of both anthropogenic and natural fluxes of carbon using a combination of atmospheric trace gas measurements, remote sensing, and spatiotemporal statistical data fusion methods. AGU Outstanding Student Paper Awardee Wu Sun (Postdoctoral Associate)Wu Sun is a Postdoctoral Research Associate in Michalak Lab. His research aims to understand patterns and variability in terrestrial photosynthesis through the synergy between observations and process-based models. He is currently using geostatistical approaches to constrain the patterns of photosynthesis in North America. Before joining Michalak Lab, Wu obtained his B.Sc. in Geology from Nanjing University and Ph.D. in Atmospheric and Oceanic Sciences from UCLA. His research focused on using carbonyl sulfide (COS) to infer ecosystem photosynthesis. His Ph.D. work used chamber observations and reactive transport modeling to understand COS exchange between soils and the atmosphere. His latest work explored applications of COS as a leaf-scale tracer for stomatal conductance. He is transitioning from a frequentist to a Bayesian.
