Our Research

Our 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.

Profile

Bio

Dr. Anna M. Michalak is the Director of the Department of Global Ecology of the Carnegie Institution for Science and a Professor in the Department of Earth System Science at Stanford University. Prior to joining Carnegie, she was the Frank and Brooke Transue Faculty Scholar and Associate Professor at the University of Michigan. She holds a Ph.D. and M.S. in Civil and Environmental Engineering from Stanford University, and a B.Sc.(Eng.) in Environmental Engineering from the University of Guelph, Canada.

Dr. Michalak studies 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. She also explores climate change impacts on freshwater and coastal water quality via influences on nutrient delivery to, and on conditions within, water bodies. Her 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.

She is the lead author of the U.S. Carbon Cycle Science Plan, a former Editor of the journal Water Resources Research, and Chair of the scientific advisory board for the European Integrated Carbon Observation System. She is the recipient of the Presidential Early Career Award for Scientists and Engineers (nominated by NASA), the NSF CAREER award, and the Leopold Fellowship in environmental leadership.

  • Tristan Ballard (Graduate Student)

    Tristan’s research focuses on understanding how historical and future meteorological and climate variability impact riverine ecosystems. 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.

     

  • Kelsey Foster (Graduate Student)

    Kelsey is a first year PhD student in the Department of Earth System Science at Stanford. She is broadly interested in the impacts of greenhouse gas emissions on different components of the Earth system. More specifically, she is interested in studying biospheric carbon flux variability and anthropogenic methane emissions. Her prior research focused on quantifying anthropogenic methane emissions in California, with a focus on emissions from oil refineries.

  • Julian Merder (Postdoctoral Fellow)

    With the help of mathematical models and statistics I try to tackle ecological questions ranging from molecular up to global scales. During my PhD, I developed statistical techniques and software to improve the performance of ultrahigh-resolution mass spectrometry and derived new ways to link the composition of dissolved organic matter to biotic and abiotic factors. I am generally interested in all branches of ecology to better understand and quantify the dangers we will face under anthropogenic climate change. In the Michalak Lab, I will develop stochastic population models in conformance with global datasets to better understand the causes and frequencies of harmful algal blooms under changing climate.

  • Mae Qiu (Scientific Programmer)
  • Nina Randazzo, Graduate Student

    Nina Randazzo (Postdoctoral Fellow)

    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.
  • Wu Sun, Postdoctoral Research Associate

    Wu Sun (Postdoctoral Fellow)

    Wu Sun is a Postdoctoral Research Associate in the Michalak Lab at the Department of Global Ecology, Carnegie Institution for Science. His research aims to understand the variability of terrestrial carbon fluxes across scales by leveraging leaf-scale, atmospheric, and space-borne observations, terrestrial biosphere models, and atmospheric inverse modeling. His current research uses atmospheric observations and remotely sensed photosynthetic proxies to constrain space-time patterns of North American carbon fluxes from divergent model estimates.

    Before joining the Department of Global Ecology at Carnegie, 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) measurements to infer photosynthesis. His Ph.D. work combined chamber observations and reactive transport modeling to understand physical and biotic drivers of COS exchange between soils and the atmosphere. His latest work explored applications of COS as a leaf-scale tracer for stomatal conductance.
