      I am working within the SPATIAL group in the Department of Geology and Geophysics. My research topics in Utah stem from the NSF-funded CO2PIP project which aims to provide updated reconstructions of atmospheric pCO2 over the past 500 million years. This will be achieved through forward modeling integrated pCO2 proxy systems (e.g., boron isotopes, pedogenic carbonate, etc.).

      • Jan 2019 - Jan 2022

      I am working closely with my postdoctoral advisor (Marina Suarez) at KU on research projects which involve: • Utilizing carbonate petrography and cathodoluminescence (CL) to identify different stages of mineral growth in paleosol carbonates from NW China. • Generating stable isotope records (δ13C, δ18O and “clumped isotopes”) from these terrestrial carbonates and interpreted changes in climate and the hydrologic cycle. • Compiling Aptian-Albian paleoclimate and sedimentological data, linking terrestrial and marine records of climate and environmental change.

      • Sep 2012 - Dec 2018

      I use fossils of single-celled calcifying marine organisms (foraminifera) to reconstruct periods of climate change in the Late Paleocene and Early Eocene by measuring the chemistry of the shells that they secrete. Geochemical proxies such as stable carbon, oxygen, and boron isotopes, as well as B/Ca and Mg/Ca measurements are utilized in order to quantify past atmospheric carbon fluctuations, seawater pH, temperature, and salinity. These data are then used as constraints on numerical climate/carbon cycle simulations in order to better understand the nature of the coupling between climate/climate feedbacks and the carbon cycle both in terms of long term climate trends and short term climate perturbations.

    • Associate Instructor
      • Apr 2017 - Jun 2017

      I served as a Graduate Student Instructor for "Elements of Field Geology" (EART-109) in the Earth and Planetary Sciences department at UC Santa Cruz. As Associate Instructor, I organized and generated new curriculum, led overnight field trips, and held lectures. The course introduced concepts in geologic mapping, stratigraphic interpretation, sedimentology, and structural geology to undergraduate students in the Earth Sciences major.

    • Stratigraphic Correlator
      • Jul 2017 - Sep 2017

      I sailed on the JOIDES Resolution as a Straitgraphic Correlator for IODP Expedition 371: Tasman Sea Subduction Initiation and Paleogene Climate. While aboard, I monitored physical properties data in real-time to inform drill decisions of secondary holes, and generated ties in order to link stratigraphically similar features from hole to hole with the goal of generating a continuous spliced record. Further, I identified Cenozoic climate events using physical properties, biostratigraphic and paleomagnetic data. Show less

  • Shell
    • Houston, Texas Area
    • Geology Post-Grad Intern
      • Jun 2014 - Sep 2014

      My research at Shell focused on geochemical proxy-based paleocenaographic reconstructions of pCO2, salinity, upwelling, and temperature gradients in the oceans in order to test the validity of numerical model simulations that have been applied to late Cretaceous Ocean Anoxic Events (OAEs), specifically OAE2 at the Cenomanian-Turonian boundary. These proxy-based reconstructions are compared to simulated output in order to determine the reliability of numerical models. This research is one part of the larger team goal of understanding depositional environments of source mudrocks during OAE2. Show less

    • Supervisor
      • Jun 2008 - Dec 2010

      I managed other technicians; fed, medicated and looked after boarded dogs, while finishing undergraduate studies. I managed other technicians; fed, medicated and looked after boarded dogs, while finishing undergraduate studies.
