Research Philosophy

My work is grounded in pragmatic innovation. I focus on advancing methodological research in applied artificial intelligence, with an emphasis on fairness, robustness, and equity. My goal is to bridge cutting-edge AI methods with real-world clinical impact by developing solutions that improve decision-making, reduce disparities, and meaningfully benefit patients and communities.

Selected Projects

Reliable and Robust Clinical AI

Algorithmic Fairness & Uncertainty Quantification

• Designed fairness auditing frameworks for clinical risk prediction models across chronic kidney disease, substance use disorder, and oncology datasets, integrating novel mitigation techniques and benchmarking against existing approaches (JCO CCI, AIME 2025, IEEE ICHI 2024, IEEE ICHI 2023).
  • Leveraged over 10 years of clinical nursing experience to guide feature engineering and problem formulation, distinguishing true physiological signal from artifacts of clinical workflow.
  • Quantified disparities in readmission prediction and treatment completion, demonstrating how commonly used fairness metrics fail to capture systemic healthcare inequities.
• Developed a Neighborhood-Adaptive Difficulty Score combining k-nearest neighbor topology with conformal prediction to distinguish model limitations from inherent case complexity.

Real-World Evidence & Health Disparities Modeling

• Developed a mixed-order Markov chain simulation using VA Corporate Data Warehouse data to model prostate cancer treatment sequences and identify empirically observed pathways associated with elevated mortality risk across racial groups.
  (Manuscripts in preparation)
• Conducted a national registry study using the AAO IRIS® Registry to quantify racial and gender disparities in retinal vein occlusion treatment via multivariable logistic regression, highlighting inequities in access to anti-VEGF therapy (Ophthalmology Retina).

Clinical NLP & Large Language Model Evaluation

• Developed EnsReas, an iterative prompting framework that improved medical question-answering accuracy and consistency on USMLE datasets (+3-5%) across both closed (GPT-4) and open-source clinical LLMs (JAMIA).
• Applied open-source clinical LLMs to extract pathologic TNM cancer stage from real-world pathology reports without labeled training data, demonstrating that prompting and ensemble-based reasoning can achieve competitive performance and improved consistency relative to fine-tuned BERT baselines (AIME 2024, IEEE ICHI 2024).
• Designed and evaluated an LLM-assisted pipeline to automate extraction of population demographics from biomedical literature, enabling scalable equity analysis (International Journal of Digital Curation).
