Ha Nguyen

Hello! I am a fourth-year Ph.D. student in the Department of Statistics and Data Science at Cornell University in Ithaca, New York. I’m fortunate to be advised by Prof. Sumanta Basu and Prof. Martin Wells. I graduated with a BA in Math and Psychology from St Olaf College in 2019.

Prior to Cornell, I worked in healthcare consulting at Analysis Group in Boston, where I analyzed large-scale clinical trial and electronic health records (EHR) data for studies in treatment effectiveness, real-world evidence, and precision medicine. My current PhD research spans two complementary directions:

  • Designing statistically-principled, tuning-free methods for estimating high-dimensional graphical models.
  • Developing computational neuroscience frameworks to evaluate the stability and predictive utility of functional connectivity (FC) networks derived from fMRI data.

These two lines of work share a common goal: improving how we estimate and evaluate complex, high-dimensional networks from limited or noisy data. I enjoy thinking about what makes an FC measure meaningful, from stable estimation to its ability to predict phenotypes or clinical outcomes in practice.
