👋About Me

I am a third-year PhD student in Management Science and Engineering (MS&E) at Stanford University, where I am advised by Professor Margaret Brandeau and Professor Marissa Reitsma. My research focuses on health policy, decision science, and clinical toxicology. Currently, I am developing AI-augmented decision models and simulations to inform the design and evaluation of health programs and interventions.

Leveraging plasma concentrations to optimize extracorporeal treatment in acute diquat poisoning: A multi-center retrospective cohort study. Clinical Toxicology, 1–12, 2025.
  • This multi-center retrospective cohort study aimed to evaluate the clinical value of plasma diquat concentrations in guiding personalized extracorporeal treatment regimens for patients with acute diquat poisoning.
  • This study included 163 patients with acute diquat poisoning, and they were divided into three groups based on plasma diquat concentrations measured upon presentation to the emergency department: low (<100 μg/L), medium (100–1,000 μg/L), and high (≥1,000 μg/L).
  • In the low concentration group, all 66 patients survived, regardless of the extracorporeal treatment used. In the medium and high concentration groups, 5 patients who refused extracorporeal treatment died, whereas 92 patients who received extracorporeal treatment had a case fatality rate of 48.9%.
  • In the high concnetration group, among those treated with a combination of hemoperfusion and continuous veno-venous hemodiafiltration, the time interval from the end of hemoperfusion session to the initiation of continuous veno-venous hemodiafiltration was, on average, shorter for survivors than deaths (3.7 h versus 4.7 h).

Severity indices of diquat poisoning for triage and prognosis in acute diquat poisoning: A multi-center prospective cohort study. Annals of Emergency Medicine, 2025, 85(6), 512-520.
  • This study developed and validated severity indices for diquat poisoning (SIDPs) that enable emergency physicians to assess mortality risk for triage and 28-day prognosis using self-reported clinical data and laboratory biomarkers.
  • This multicenter cohort study involved 204 patients. Predictors identified by the Burota algorithm and stepwise Cox regression were incorporated into Cox proportional hazards models to develop SIDPs, one for triage and one for prognosis (SIDP-T and SIDP-P, respectively).
