Klaus Lackner is the Ewing Worzel Professor of Geophysics at Columbia University, where he is also the Director of the Lenfest Center for Sustainable Energy, Director of the M.S. Program in Carbon Management, and a member of the Earth Institute faculty. From 2006 to 2012 he was the Chair of the Department of Earth and Environmental Engineering. Lackner’s current research interests include carbon capture and sequestration, air capture, energy systems and scaling properties (including synthetic fuels and wind energy), energy and environmental policy, lifecycle analysis, and zero emission modeling for coal and cement plants.

Lackner’s scientific career started in the phenomenology of weakly interacting particles. While searching for quarks, he and George Zweig developed the chemistry of atoms with fractional nuclear charge. He participated in matter searches for particles with a non-integer charge in an experiment conducted at Stanford by Martin Perl and his group. After joining Los Alamos National Laboratory (LANL) in 1983, Lackner became involved in hydrodynamic work and fusion-related research. He was a scientist in the Theoretical Division, but also an active part of the Laboratory’s upper management. He was instrumental in forming the Zero Emission Coal Alliance and was a lead author in the IPCC Report on Carbon Capture and Storage. In 2001, Lackner joined the faculty at Columbia University. In 2004, he became a member of Global Research Technologies, LLC, which is now known as Kilimanjaro Energy, Inc.

Lackner earned his degrees from Heidelberg University, Germany: the Vordiplom, (equivalent to a B.S.) in 1975; the Diplom (or M.S.) in 1976; and his Ph.D. in theoretical particle physics, summa cum laude, in 1978. He was awarded the Clemm-Haas Prize for his outstanding Ph.D. thesis at Heidelberg University. Lackner held postdoctoral positions at the California Institute of Technology and the Stanford Linear Accelerator Center before beginning his professional career, and he attended Cold Spring Harbor Summer School for Computational Neuroscience in 1985. Lackner was also awarded the Weapons Recognition of Excellence Award in 1991 and the National Laboratory Consortium Award for Technology in 2001.

Peter Kelemen has recently added mineral carbonation and hydration in peridotite and mafic rocks to my research program. This is a reactive transport problem, very similar to the work he has done on reactive transport of melt in the upper mantle and lower crust, there are fantastic field areas where active, ongoing mineral carbonation and hydration can be observed, and the physical mechanisms that control key processes are not well understood. He is focusing on understanding processes in natural systems, particularly “reaction driven cracking”, with relevance to engineered geological capture and storage of CO2, stimulation of geothermal reservoirs, in situ mining, and extraction of hydrocarbon resources from tight formations.

For decades, Kelemen’s primary research interest has been in the genesis and evolution of the Earth’s crust in the ocean basins, in arcs, and in continents. He approaches this topic from the perspective that reactions between melt and rock during transport through the upper mantle are as important as melting, mixing, and crystal fractionation processes in producing different crustal bulk compositions in different tectonic settings. He has been fascinated by the stark compositional difference between oceanic and continental crust, and in his research Kelemen has gravitated toward end-member examples of magmatic processes: oceanic spreading ridges, and subduction-related volcanic arcs such as the Aleutians where the composition of average lavas and exposed plutonic rocks closely resembles continental crust. In an ongoing effort, he has tried to develop a general theory that explains how reactive melt transport varies along different geothermal gradients, with, 1. mineral dissolution and focusing of flow into high permeability channels in hot, upwelling mantle, 2. diffuse flow where there is a low melt flux into conductively cooled, shallow mantle, and, 3. hydrofracture where high melt flux and crystallization due to cooling clog porosity, leading to ponding of magma and increasing melt pressure. He has also become very interested in gravitational instabilities that can remove dense lithologies from the base of the crust, and transport buoyant subducted sediments and felsic igneous rocks from subduction zones back into the crust, and he hopes to pursue investigations of metasediments in lower crustal granulite terrains: how do they get down there?

In studying layered intrusions and lower oceanic crust, Kelemen has tried to understand a few of the many possible mechanisms for forming both compositional and modal layering in gabbros, via injection of layer parallel sills, and via sudden changes in pressure that can modify the assemblage of minerals precipitating from a cooling magma. This research led to general ideas about formation of oceanic crust, via a “sheeted sills” mechanism in which the lower crust crystallizes from many small sills, injected at depths throughout the crust. This end-member process stands in contrast to the “gabbro glacier” hypothesis, in which all oceanic plutonic rocks crystallize in a single, shallow melt lens and undergo ductile flow downward and outward to “fill” the lower crust. A related issue is the mode of cooling of the oceanic lower crust; via conduction with limited, diffuse fluid flow, or via rapid, focused hydrothermal convection. Trying to quantify and constrain these hypotheses, and to determine which processes predominate in different tectonic settings, has motivated a lot of research over the past 15 years.

Kelemen was a founding partner of Dihedral Exploration, mineral exploration consultants specializing in field work requiring technical climbing skills. Searching for ore deposits took me to British Columbia, Alaska and Greenland. He recently started teaching a new course, Earth Resources for Sustainable Development, which covers some of that field, as well as energy resources, water, soil and fertilizer. He has also been writing general articles and giving public presentations on this topic.

Kelemen received his Ph.D. from the University of Washington, his M.S. from the University of Washington and his B.A. from Dartmouth.

Phone:(212) 854-1494

Maria Uriarte is an Associate Professor in the Department for Ecology, Evolution and Environmental Biology at Columbia University. Through an integrated program of empirical and quantitative approaches, research in her lab examines forest ecological dynamics in response to natural disturbance and human land use. Research projects focus on disturbance ecology, forest succession, and community assembly. Field sites span geographic regions where forests have been subject to different forms of anthropogenic disturbance, including fire, hurricanes, fragmentation, and expansion of tree plantations. The methodological thread that unites the diverse research projects housed in the Uriarte lab is the application of spatially-explicit modelling techniques, simulation, and other advanced statistical and modelling tools to understand and forecast the dynamics of tropical forests ecosystems in response to disturbance. Her current projects include studies of the dynamics of deforestation and reforestation in post-agricultural landscapes of Puerto Rico, the effects of fires in agriculture-forest mosaics in the Peruvian Amazon, and seed dispersal processes in fragmented forests in the Brazilian Amazon. Prior to Columbia, Uriarte was a Postdoctoral Fellow at the Cary Institute for Ecosystem Studies.

Uriarte received an M.S. in Environmental Studies from Yale University, and her Ph.D in Ecology and Evolutionary Biology from Cornell University.
