Research in the Keutsch group is aimed at improving our understanding of photochemical oxidation processes of volatile organic compounds (VOCs) that produce tropospheric ozone (O3) and are central to secondary organic aerosol (SOA) formation. O3 and aerosol affect human health and climate, and uncertainties in the radiative effects of aerosol comprise the largest uncertainties in current estimates of anthropogenic forcing of climate. Our scientific approach builds on enabling new field observations of key VOC oxidation intermediates (OVOCs) via instrumentation and method development.

Elsie Sunderland

Gordon McKay Professor of Environmental Chemistry
Professor of Earth and Planetary Sciences

Elsie M. Sunderland is the Gordon McKay Professor Environmental Chemistry at the School of Engineering and Applied Sciences and in the Department of Environmental Health in the Harvard School of Public Health, and an affiliated faculty member of the Department of Earth and Planetary Sciences.  She is a Faculty Associate in the Harvard University Center for the Environment and the Harvard Center for Risk Analysis. 

Research in the Sunderland Lab focuses on how biogeochemical processes affect the fate, transport and food web bioaccumulation of trace metals and organic chemicals. Her group develops and applies models at a variety of scales ranging from ecosystems and ocean basins (e.g., the Gulf of Maine, the North Pacific and Arctic Oceans) to global applications to characterize how changes in climate and emissions affect human and ecological health, and the potential impacts of regulatory activities. Her group also makes key measurements of chemical concentrations and reaction rates in environmental samples (natural waters, sediments, and aquatic biota) and humans (hair, blood) to parameterize and evaluate environmental models.

Ongoing research is elucidating the biogeochemical cycling of compounds with contrasting physical and chemical properties that can be used to obtain insights into the varying exposure pathways and environmental lifetimes for industrial chemicals. The innovation in this work is to quantitatively analyze the entire exposure pathway for these compounds to identify their properties in air and water (e.g., stability in the atmosphere, photodegradation in water, environmental partitioning behavior) that enhance chemical persistence and ultimate accumulation in biota.

Upwelling in the Equatorial Pacific Ocean

Vertical velocities in the ocean are prohibitively slow to measure directly, so physical oceanographers have been attempting to estimate them by other means for several decades. There is strong motivation to do so; upwelling fuels marine life by bringing nutrient-rich water into the sunlit surface layer. Upwelling also affects the atmosphere by cooling the surface, which affects wind and clouds. The surprising abundance and diversity of life—from corals to fish to seabirds—around equatorial islands, has been...

Talk Title:  From Microbial to Global: What Mercury Stable Isotopes Can Tell us about Mercury Bioaccumulation

Abstract:  Mercury (Hg) stable isotopes have become a standard approach to study Hg sources and processes in the environment. Despite the power of these tools, applying Hg isotopes to understand source to receptor relationships can be difficult due to the myriad of...

Abstract: As more than 70% of fossil fuel-based carbon dioxide (CO2) is emitted in urban areas, urban greenhouse gas (GHG) emissions play a crucial role in achieving the emission reduction goals. In addition, air pollutants, such as nitrogen oxides (NOX), and particulate matter (PM) adversely affect urban air quality and are harmful to human health. In this talk, I will present new observational methods and modelling approaches to address two of the most urgent challenges of our time: climate change and air pollution.

I will present a novel...

Ding Ma

Associate
Kuang Group

Ding Ma received his Ph.D. in Earth and Planetary Sciences from Harvard University. Advised by Prof.ZhimingKuang, his dissertation research investigated three dominant patterns of large-scale atmospheric variability, namely the South Asian monsoon, Madden-Julian Oscillation and the annular mode.Beforemoving back to Harvard, he was an Earth Institute Fellow at Columbia University, where he was working with Prof. Adam Sobel to explore extreme weather associated with large-scale variability. His work emphasizes a combination of observational analysis andnumerical modeling. Guided by observations, numerical experiments are designed and conducted to pursue a better theoretical understanding of the large-scale atmospheric variability in the past, present and future. The main goal of his work is to identify essentialphysical mechanisms governing the large-scale circulation variability.... Read more about Ding Ma
