Program Co-Director

Brad Linsley is a Lamont Research Professor and Director of the Lamont-Doherty Stable Isotope Laboratory. He came to Lamont in 2011 after 16 years as a Professor in the Department of Atmospheric and Environmental Sciences at the University at Albany-SUNY. Brad is from the Connecticut shore where he developed a life-long interest in the oceans. Following his Ph.D. research in marine sediment core-based paleoceanography at the University of New Mexico, Brad began working with and developing the use of massive corals as recorders of past oceanographic and climate conditions while a postdoctoral associate at Rice University in Houston. Since then the sediment and coral facets of his research have taken him to remote sites across the Pacific studying sediment cores and corals from sites in Panamá, Clipperton Atoll, California margin, Tabuaeran (Fanning Atoll), Hawaii, Rarotonga, Fiji, Tonga, American Samoa, the Great Barrier Reef, the Makassar Strait in Indonesia, the Sulu Sea, and the New Guinea margin. Back in the lab, meticulous work on the coral cores generates near-monthly resolved geochemical reconstructions of water temperature, salinity, and anthropogenic carbon flux into the ocean over the last several centuries. The sediment cores are used to make deeper-time reconstructions of surface, intermediate, and deep water conditions in the far western Pacific. Over his career, Brad has developed influential paleoclimate records from the circum-Pacific that have significantly advanced our understanding of interannual-multidecadal climate dynamics and millennial-scale variability in the ocean.


Frank Nitsche is a research scientist at the Lamont-Doherty Earth Observatory of Columbia University. He studies
sediment processes and morphological features of coastal areas including the Hudson River Estuary and the Long
Island Sound. In addition, he investigates seafloor features of the Antarctic continental margin and is reconstructing
past ice stream dynamics and the vulnerability of the Antarctic Ice Sheet. In his research he uses mostly geophysical
mapping techniques and data integration through GIS.

Nitsche teaches in Columbia’s Masters programs in Sustainability Science. He previously has taught an Environmental
Data Analysis course at Barnard College and coordinated environmental field classes on the Hudson River.

Nitsche received a Diploma (Master of Science) in geophysics from the University of Kiel, Germany and a Ph.D. from
the University of Bremen, Germany. After a post-doctoral position at ETH Zurich he came to the Lamont-Doherty
Earth Observatory of Columbia University in 2001 where he started as a postdoctoral researcher. He has participated in
nine ocean-going and numerous coastal expeditions. He has consulted on several environmental projects for New York
State and Connecticut State.


Ajit Subramaniam is a Lamont Research Professor at the Lamont-Doherty Earth Observatory. He has worked for the
National Oceanic and Atmospheric Administration Coastal Services Center in Charleston, SC, the University of
Maryland in College Park, MD, and the University of Southern California in Los Angeles. He has served as the
Program Director for the Marine Microbiology Initiative at the Gordon and Betty Moore Foundation and a program
manager in the Biological Oceanography Program at the U.S. National Science Foundation. Ajit earned his Ph.D. in
Coastal Oceanography and M.S. in Marine Environmental Science from SUNY, Stony Brook. He has a Bachelors
degree in Physics from The American College in India.

developed algorithms for detection of cyanobacterial blooms. Subramaniam has taught at the Austral Summer Institute,
Universidad de Concepción in 2004, 07, and 10 and was awarded a Fulbright Specialist Award in 2010 for this. He was
awarded a Mercator Fellowship by the University of Rostock and the Baltic Sea Research Institute, Germany in 2017.


Geochemist Lex van Geen holds a research professor appointment at Lamont-Doherty Earth Observatory and is member of the Earth Institute’s faculty at Columbia University. His current research focuses on ways to reduce the impact of the environment on human health. For two decades, he coordinated earth-science and mitigation efforts under Columbia’s Superfund Research Program on the origin and health effects of elevated levels of arsenic in groundwater. A theme that runs through this and other on-going project, e.g. concerning fluoride in groundwater in India, bauxite dust in Guinea, or soil contaminated with lead from mine-tailings in Peru, is that patterns of contamination are spatially very heterogeneous. This complicates prediction but often also points the way to mitigation when the hazard can be mapped. For this reason, Van Geen is a firm believer in the more widespread use of field kits by non-specialists to reduce exposure to environmental toxicants, particularly in developing countries. He collaborates with public health and social scientists to evaluate how such kits can be deployed at scale and has published over 150 peer-reviewed papers on this and other environmental topics.   


Dr. Beizhan Yan received his Ph.D. in Geology in 2004 from Rensselaer Polytechnic Institute (RPI), Troy, NY and currently he is a Lamont Associate Research Professor at Lamont-Doherty Earth Observatory (LDEO) of Columbia University. His Ph.D. study at RPI (2000-2004) focused on the source apportionment of polycyclic aromatic hydrocarbons (PAHs) in urban waters. After two years of postdoc in Idaho National Laboratory, he joined Washington University in St. Louis to study nanoscale size effects on biogeochemical processes for environmental bioremediation.
This research has important implications for the immobilization of uranium and the biodegradation of aromatic compounds at contaminated sites. In 2007, he joined LDEO as an institutional postdoctoral fellow. Since then, he has established an Environmental Organic Geochemistry Lab with the ability to extract, isolate, and identify organic contaminants and
biomarkers from environmental and biological samples.

Using source-sensitive indicators and compound-specific stable isotope ratios, he has successfully traced metals and aromatic hydrocarbons in the waters and air of NYC and linked the exposures of these air pollutants to pediatric asthma outcomes. He is also leading a collaborative study to examine the association between pediatric respiratory outcomes and air pollutants in Beijing China. To determine possible impacts of hydrofracking on air and water quality and health outcomes, he is conducting a collaborative study in adjacent counties of western NY (Broome, Tioga, and Chemung) and northern PA (Susquehanna, Bradford, and Tioga).


Dr. Brendan Buckley holds the position of Lamont Research Professor, and has been a long-time member of the Tree
Ring Lab at the Lamont-Doherty Earth Observatory of Columbia University (LDEO). While he has worked in locations
around the globe, Buckley has been one of the pioneers of tropical dendroclimatology, having produced the longest and
best replicated records of absolutely dated tree ring sequences from Southeast Asia. He continues this important work
by using new methods to develop discrete seasonal reconstructions of regional hydroclimate, including measures of the strength of summer and winter monsoons, as well as the “shoulder” seasons that lead into and out of them, over the past
millennium. He has a long history of research in Asian tropics and the North American boreal forests, having conducted some of the first dendroclimatic forays in northern Canada, and North America’s northernmost trees in the Firth River of Alaska. He was also instrumental in developing the longest temperature reconstructions from the Southern Hemisphere as part of his PhD research in Tasmania and New Zealand.

Buckley received his undergraduate degree in Physical Geography from Plymouth State College in New Hampshire, a
Masters degree from Arizona State University in Tempe, and his PhD from the Institute of Antarctic and Southern Ocean Studies (IASOS) at the University of Tasmania, Australia. He held Post-doctoral positions at the University of Auckland, New Zealand and at the Lamont-Doherty Earth Observatory of Columbia University, before commencing his current LDEO position in 1999.


Dr. Chillrud, Lamont Research Professor, is an environmental geochemist interested in public health research. Much of
his work is focused on the role of particles in the transport, behavior and fate of chemical contaminants. These particles
can be fine-grained sediments in surface water bodies, such as the Hudson River, sandy particles in groundwater aquifers, or airborne particles in indoor and outdoor settings. He has worked for over 25 years studying contaminant issues at Superfund sites, including developing and testing enhanced remediation methods for contaminated aquifers.

His research on air pollution seeks to understand the sources, behavior, and exposure pathways of airborne contaminants, as well as designing and testing new air monitoring devices, either to be used at fixed indoor and outdoor locations, or to be worn by people. He also serves as the Director of the Exposure Assessment Facilities Core of the Columbia Center for Environmental Health in Northern Manhattan.
