Curriculum Vitae

Biography

I am currently a Research Scientist at Lawrence Berkeley National Laboratory. I received MS in nuclear engineering (2006), MA in statistics (2010), and PhD in nuclear engineering (2010) at University of California, Berkeley. My initial research interest was to investigate the environmental impact of nuclear waste and nuclear weapon productions. My PhD dissertation focused on Bayesian geostatistical inverse modeling for subsurface characterization at the uranium-contaminated DOE Hanford site. Since then, I have broadened my research interest to various environmental problems, including Arctic ecosystem responses to climate change, groundwater contamination, and deep-subsurface CO₂ storage. In addition to working in many interdisciplinary projects, I am a deputy lead of the site application thrust in the Advanced Simulation Capability for Environmental Management project, leading the site application at the Savannah River Site F-Area. I am also in the leadership team of Institute for Resilient Communities, which aims to prepare communities for radiological and other disasters through research, education and outreach activities.

Research Interests

My research aims to improve understanding and predictions in Earth and environmental systems through mechanistic modeling and statistical data analysis. I have been developing a Bayesian hierarchical model and other statistical methods to integrate multi-type and multiscale datasets (including point measurements, geophysical techniques, and remote sensing data) for estimating spatially heterogeneous subsurface and ecosystem properties. In parallel, I have been developing large-scale numerical models to predict future risks of environmental contamination and geological CO₂ storage, and also to develop effective remediation and monitoring strategies.

I also work extensively at the interface of modeling and data analysis to better integrate complex models and datasets. I have developed and applied various mathematical methods for the data-model integration including inverse modeling, and sensitivity/uncertainty analysis methods. I implemented the global sensitivity analysis module within environmental software (iTOUGH2), and wrote a manual and introductory paper.

My research goal is to develop a framework to connect data and models in a seamless manner, and to create a feedback loop so that we can iteratively improve our system understanding and reduce the uncertainty in overall predictions. My current research covers various topics in Earth and environmental sciences:

Groundwater contamination and remediation: I am leading an effort to develop a three-dimensional flow and reactive transport model at the Savannah River Site F-Area, which is contaminated by low-level nuclear waste solutions. We are performing parameter estimation, and uncertainty/sensitivity analysis to better understand the system and quantify the uncertainty in predictions. The goal is to design effective remediation and cost-effective long-term monitoring strategies. Here is my video (Advanced Simulation Capability for Environmental Management
Arctic ecosystem science: I have been characterizing various spatially heterogeneous properties critical to predict terrestrial feedbacks to climate change, including soil moisture, thaw depth, snow depth, vegetation dynamics, metal concentrations, and carbon fluxes. I have developed a Bayesian-based method and a cluster analysis-based method to integrate various datasets including point measurements, geophysics, and remote sensing data. Here is the highlight of the paper (Next Generation Ecosystem Experiment-Arctic)
Biogeochemical cycling: I have developed a Bayesian hierarchical model to integrate geophysical (induced polarization) and wellbore data for estimating spatially heterogeneous biogeochemical properties and identifying biogeochemical hotspots in a minimally invasive manner (Sustainable Systems Scientific Focus Area/Watershed Function Scientific Focus Area)
Radionuclide contamination after the Fukushima Nuclear Power Plant accident: I have been developing a Bayesian geostatistical method to integrate multiscale datasets of radiation dose rates, including hand-held, car-borne and airborne surveys.
Geological CO₂ storage: Using a three-dimensional multiphase flow model, I have simulated the regional pressure increase and CO₂ plume migration at Southern San Joaquin Basin in California, USA (hypothetical scenarios). The simulation results are also being used to evaluate various risks, including leakage through faults and induced seismicity (National Risk Assessment Partnership)
