Rama Chakrabarti (Origins Fellow)
Research includes application of Nd, Sr, Pb and Hf isotopes as well as major and trace element concentrations on Proterozoic to recent Earth processes. I have worked on Proterozoic lamproites, massif anorthosites and Vindhyan basin sediments from India, Cenozoic volcanics from Western Anatolia, recent volcanics from the Nyiragongo and Nyamuragira volcano in the East African rift including a U-Th series disequilibria study of these lavas, Lonar Impact Crater in the Deccan and the Utica Shale Magnafacies of North America. In addition, I have a keen interest in Precambrian trace fossils and geochemical signatures of early life. At present, I am working on High-precision Chronology of the Early Solar System with Dr. Stein Jacobsen.

Development/optimization of new Quantum Cascade Laser (QCL) spectrometers for accurate in situ measurements of atmospheric CO, CH4, N2O, and CO2 concentrations.
Analysis of CO2 tracer clocks observed from research aircraft in the tropical tropopause layer: Inferring the mean age and age spectrum for the tropical upper troposphere and lower stratosphere (UTLS) and determining distributions in the TTL of short-lived organic/inorganic halogens and non-methane hydrocarbons with surface sources and their inputs into the stratosphere. Global-scale observations of atmospheric tracers (CO2, CH4, CO, N2O) from the surface to the tropopause through the annual cycle: Testing global transport models to distinguish which accurately simulate vertical and meridional tracer distributions and determining the distribution of sources and sinks for CO2 and other major atmospheric tracer gases.

Reginald A. Daly Post-Doctoral Fellows
Bill Boos
Dr. Boos studies the physical processes responsible for variations in tropical climate over a broad range of time scales, using theory, numerical models, and observational analyses. His doctoral research focused on understanding why the circulation in a rotating fluid in which water undergoes phase changes can intensify abruptly as a heating is slowly increased, with the motivation of understanding the abrupt onset of monsoon circulations in South Asia. Currently, he is studying the physics of a dominant type of variability in monsoon climates that produces excess or deficient rainfall on time scales of several weeks. He is more broadly interested in the interaction of moist convection and cloudiness with the large-scale atmospheric circulation, and in how this circulation might differ in past and future climates.

Matija Cuk
Dr. Cuk's interests lie mostly in the field of planetary dynamics, both in our and other solar systems. Presently, he is exploring the dynamical history of the Earth-Moon system, with the particular focus on the Lunar Cataclysm (an episode of intense impact cratering of the Moon 3.9 billion years ago). His other research topics include the interactions between planetary migration and orbital resonances during the early history of planetary systems, and the effects of absorption and re-radiation of sunlight on the orbits and spins of small asteroids and their satellites.

Giampiero Iaffaldano
Dr.Iaffaldano's research aims at a detailed understanding of the magnitude and spatial distribution of driving and resisting forces in Plate Tectonics, for which he uses numerical simulations of global lithosphere dynamics performed in conjunction with 3-D mantle circulation models.

Eric Dunham
Studies the connection between earthquake source physics and strong ground motion. This involves developing analytical and numerical models to explore the behavior of propagating ruptures. Previous work focused on the influence of rupture velocity, in particular velocities exceeding the shear-wave speed, on the character of seismic-wave radiation in the vicinity of faults. Current interests focus on the conditions that give rise to such supershear earthquakes.
