Overview

I am a PhD student in Statistics at Texas A&M specializing in hierarchical modeling, uncertainty quantification, and model validation. I value collaborative problem-solving, mentorship, and communicating statistical work with clarity and transparency.

Experience

Doctoral Researcher in Statistics

2022 - Present
Texas A&M University
  • Develop Bayesian hierarchical and latent-variable models for prevalence estimation and diagnostic testing without a gold standard.
  • Design simulation studies to evaluate identifiability, parameter recovery, robustness, and uncertainty quantification.
  • Develop a latent severity extension to reduce model complexity and improve estimation in sparse-data settings.

Instructor, STAT 211 - Principles of Statistics I

Fall 2026
Department of Statistics, Texas A&M University, College Station, TX
  • Serve as instructor for an undergraduate introductory statistics course covering probability, statistical inference, hypothesis testing, and regression.
  • Teach students to perform exploratory and inferential statistical analyses using R and interpret results in real-world contexts.
  • Develop and deliver course materials, assessments, and statistical computing instruction for an asynchronous online course.

PhD Statistics and Data Science Internship

Summer 2025
Lubrizol Corporation, Wickliffe, OH
  • Developed and deployed credible intervals for predictive models, improving reliability of forecast.
  • Designed repeatability and reproducibility experiments, strengthening product validation.
  • Built predictive models linking chemical composition to transmission fluid performance to guide the data-driven product development decisions.

Biostatistics Research Assistant

Aug 2021 – May 2023
Institute of Biosciences and Technology, Texas A&M University (Dr. Kurt Zhang Lab), Houston, TX
  • Applied high-dimensional regression and clustering methods to DNA methylation data, identifying biomarkers linked to disease pathways.
  • Analyzed NHANES data to evaluate dietary risk factors for hypertension in pregnancy, contributing to peer-reviewed publications.

Projects

Selected work in experimentation, causal inference, Bayesian modeling, and applied statistical analysis.

A/B Testing and Experimental Design - Analysis of randomized product experiments, including metric definition, power and sample size calculations, treatment-effect estimation, uncertainty quantification, and experiment diagnostics.
Double/Debiased Machine Learning for Causal Inference - Applications of Double Machine Learning for causal effect estimation, including randomized trials with non-compliance and observational data with high-dimensional confounding.
Bayesian Latent Severity Modeling - Bayesian latent class modeling extended with a latent severity variable to reduce model complexity and improve estimation of disease prevalence and diagnostic test accuracy when data are limited and no gold standard test is available.
Geospatial Clustering - Geospatial analysis of New York City taxi trips to identify spatial and weekly patterns in passenger demand.
Zero-Inflated Negative Binomial Regression - Modeling overdispersed and zero-inflated infection counts to identify important predictors and characterize variation in count outcomes.
