Minjee Kim

PhD candidate in Statistics, Texas A&M

About

I am a PhD candidate in Statistics at Texas A&M University, graduating in May 2027.

My research focuses on statistical identifiability, Bayesian inference, and computational model validation. I study what can be learned from incomplete or imperfect observations, how to detect unreliable estimates, and how to quantify uncertainty in downstream predictions and decisions.

My work combines statistical methodology, Monte Carlo simulation, and applied modeling across scientific and economic problems.

Experience

Instructor, STAT 211 - Principles of Statistics I

Fall 2026
Department of Statistics, Texas A&M University
  • Undergraduate probability, estimation, testing, regression, and computation in R.

PhD statistics and data science intern

Summer 2025
Lubrizol Corporation, Wickliffe, OH
  • Credible intervals for predictive models, so uncertainty was attached to the forecast rather than reported separately.
  • Repeatability and reproducibility studies to quantify measurement variability for product validation.
  • Predictive models from chemical composition to transmission-fluid performance.

Biostatistics research assistant

Aug 2021 - May 2023
Institute of Biosciences and Technology, Texas A&M University (Kurt Zhang lab)
  • High-dimensional regression and clustering on DNA methylation data.
  • NHANES analysis of dietary risk factors for hypertension in pregnancy.
  • Developed the R package nhanesGraph for searching public-use continuous NHANES files and downloading them from the current CDC XPT URLs, 1999-2000 through August 2021-August 2023. Not an official CDC tool.
  • Analysis contributed to peer-reviewed papers listed below.

Dissertation

Chapter I — Prevalence without a gold standard. Prevalence and diagnostic accuracy are estimated from imperfect tests and heterogeneous study designs. We characterize when those parameters are identified, then estimate them with Bayesian latent-class and latent-severity models, checked by parameter-recovery simulations.

Chapter II — Cost burden. Prevalence is an intermediate. The target is a distribution over economic loss, obtained by propagating the Chapter I posterior together with uncertainty in population and cost inputs.
