Research

I am an interdisciplinary geochemist, modeler and data scientist. My research broadly uses data-driven and model-driven approaches to quantify the patterns of element flux and isotope behavior involved in the global carbon and biogeochemical cycles, especially under periods of climatic perturbations.

 

Extensive data mining, data assimilation, large-scale spatial-temporal statistical analysis, and machine learning are frequently used by my research group. We believe geo-statistics and machine learning could reveal the intrinsic patterns of nature’s processes that are sometimes extremely difficult to be captured by classical physical process models. With that being said, in areas where data is extremely limited or data-driven approaches are not suitable, numerical modeling (e.g., modeling the global carbon cycle) also serves as a critical tool in our research.

 

Some of my current research topics include building inverse modeling frameworks to understand the Earth-surface processes during carbon cycle perturbations, using geo-statistics to quantify the groundwater carbon flux to the ocean, and applying machine learning techniques to constrain the biogeochemical cycles (such as silicate weathering flux, seafloor bioturbation intensity, and stable isotope fractionations in natural environments).

 

Graduate Students Opportunities

 

I am searching for motivated MS and PhD students that are excited about biogeochemical cycles, numerical modeling and data science. Interested students should check our departmental website (https://ocean.tamu.edu/academics/graduate-programs/index.html) for the admission requirements. I strongly encourage prospective students to reach out to me by email to learn more about opportunities in my research group.
