I study geological processes utilizing isotopic effects as tracers. I have worked on diverse problems including the evolution of early earth, genesis of flood basalts, generation of oceanic lithosphere, meteorite impacts, generation of mantle heterogeneities, serpentinization and methane production on planetary surfaces, economy of osmium in the oceans and relationship between solar magnetism and terrestrial climate. More recently I have become interested in water-rock interaction during hydraulic fracturing (fracking). We are looking at diagenesis of Marcellus Shale as well as what to do with the wastewater that results from fracking. I am working on this problem with Danielle Niu (PhD student), Jessi McDaniel (MS student), Josh Landis (Research Scientist) and Prof. Devon Renock. Other projects being carried out in my lab are 1) flux of Ir and Os during the K-T boundary impact (with Prof. Jason Moore, Univ. of New Mexico and Prof. J. Kirk Cochran, Stony Brook University), 2) Test of meteorite impact hypothesis at Younger-Dryas (we are looking at Greenland ice cores with PhD student Ji-Hye Seo, Prof. Erich Osterberg,  Prof. Brian Jackson, Prof. Sungmin Hong, Korea and Dr. J. P. Steffensen, Denmark), 3) Osmium isotope composition of Solar Wind (with M.S. student Gayathri J.P., Prof. Amy Jurewicz, and Prof.  D. Burnett (Caltech) using material recovered from NASA's Genesis Mission).
