Mariia Belaia

Postdoctoral Fellow, Harvard John A. Paulson School of Engineering and Applied Sciences

Mariia is a postdoctoral fellow at the Harvard John A. Paulson School of Engineering and Applied Sciences. She holds a PhD (Dr. rer. pol.) in economics from the University of Hamburg (Germany) and the International Max Planck Research School on Earth System Modelling (IMPRS-ESM). Mariia is an environmental economist interested in theories of economic growth, decision-making under uncertainty, and dynamical systems theory. Her particular focus is the design of integrated assessment models of climate and the economy (IAMs). In her PhD dissertation, “Integrated Assessment of Climate Tipping Points”, Mariia explored the structural  characteristics of economic impacts of climate change related to climate tipping points and their associated policy implications. She is currently  analyzing the role of ethical and empirical economic assumptions in widely applied IAMs when considering the mitigation-solar geoengineering (SG) policy mix.

John Dykema

John Dykema

Project Scientist, Harvard John A. Paulson School of Engineering and Applied Sciences

John Dykema is a Project Scientist in the Harvard John A. Paulson School of Engineering and Applied Sciences. He focuses on the development of instrumentation (particularly infrared remote sensing systems) and validation of long-term data records for atmospheric model testing applications. From this perspective, quantitatively testing model performance in simulating geoengineering impacts provides a new set of observational challenges. Recent work has assessed the measurement requirements necessary to empirically quantify the risk of ozone loss posed by geoengineering through improved understanding of stratospheric chemistry and dynamics. He holds a Ph.D. in Applied Physics from Harvard University.

Sebastian Eastham

Sebastian Eastham

Visiting Scientist, Harvard's Solar Geoengineering Research Program

Sebastian is a research scientist at the Massachusetts Institute of Technology's Laboratory for Aviation and the Environment (LAE). His previous work has covered development and application of global atmospheric chemistry and transport models, ranging from his work to implement stratospheric chemistry in the GEOS-Chem community atmospheric model, through to his recent paper discussing the possible health effects of solar geoengineering. He is currently working as a visiting scientist for the Harvard Solar Geoengineering Research Program, investigating the behavior of aircraft plumes in the stratosphere - including those which would be expected to form if stratospheric aerosol injection were ever deployed.

Pete Irvine

Pete Irvine

Postdoctoral Research Fellow, Harvard John A. Paulson School of Engineering and Applied Sciences

Pete Irvine is a Postdoctoral Research Fellow at the Harvard John A. Paulson School of Engineering and Applied Sciences. Pete conducts research on the climate and broader impacts of solar geoengineering and works to put those findings into perspective with the risks posed by climate change. He works with researchers from a range of disciplines to explore the implications of solar geoengineering as a potential means of reducing the risks of climate change. Current work includes evaluating the potential effectiveness of different solar geoengineering proposals at reducing sea-level rise to determine whether solar geoengineering deployment could be optimized to increase this effectiveness.
