My research - Perfecting the Imperfect - explores machine learning under conditions of imperfect information. I focus on developing robust methods in self-supervised learning, semi-supervised learning, and learning from noisy or coarse labels. In parallel, I am dedicated to evaluating and improving the safety and reliability of imperfect models, particularly large language models (LLMs), to support their trustworthy deployment in real-world applications.

Research Interests

Including but not limited to:

  1. Robust Machine Learning under Imperfect and Complex Conditions
    Developing resilient algorithms that perform reliably in the presence of noisy data, weak supervision, or dynamic environments.
  2. Safety and Reliability of Large Language Models (LLMs)
    Investigating methods to assess and enhance the trustworthiness of LLMs, especially when deployed in real-world, high-stakes scenarios.
  3. Uncertainty Estimation and Calibration in Imperfect Models
    Improving model interpretability and decision-making by quantifying uncertainty and ensuring well-calibrated predictions.
  4. Applications in Healthcare and Medical Imaging with Imperfect Data
    Applying robust machine learning techniques to clinical and imaging data, which often contain missing values, noise, or limited annotations.
