My research interests are link through sedimentary and aqueous geochemistry. I am interested in understanding the geochemistry of sedimentary basins and how their geochemistry can be used to reconstruct paleo-environments. I am particularly keen on the reconstruction of ocean conditions across the Permian-Triassic Boundary (PTB) to understand the tempo, mechanisms, and severity of the largest mass extinction in Earth’s history.

Additionally, I am equally intrigued by modern weathering impacts on black shales and how it can lead to change in the geochemical cycles within the local watershed to the global ocean. I approach this research focus by linking my expertise in stable isotope and redox-sensitive trace element geochemistry to understand the deposition and lithification of anoxic muds, and how conditions favorable for their deposition are influenced by climate forcing and local environmental impacts. 

Lastly, the successful development of unconventional oil and gas resources and its importance in the US energy portfolio has led me to study the depositional and deformational conditions responsible for shale play areas. I approach this problem by utilizing geochemical techniques in understanding how the paleo-environment and post-deposition process create these resources.

Much of my research is lab-based using a wide-array of lab instrumentation:

  • Major and minor elements: Energy Dispersive X-ray Fluorescence (ED-XRF)
  • Trace and rare earth elements: Inductively Coupled Plasma Mass Spectrometer (ICP-MS)
  • Carbon, nitrogen, and sulfur and stable isotopes: Elemental Analyzer (EA) and Isotope Ratio Mass Spectrometer (IRMS)
