  • I strengthen statistical estimation and causal inference using machine learning techniques.

  • I build data-analytic methods for personalized digital health using an n-of-1 / single-case framework.

I am a biostatistician and data scientist at Evidation Health on the Digital Health Outcomes team. I'm also the creator and editor of Stats-of-1, a blog for personalized digital health methodology. Before that, I was a research statistician and data scientist at Clarify Health, a healthcare tech company.

I'm a General Member of the International Collaborative Network (ICN) for N-of-1 Clinical Trials and Single-Case Experimental Designs (SCEDs), chaired by Prof. Jane Nikles and Dr. Suzanne McDonald. I also run the CASIA Project for individualized discovery of health-related causes and effects using machine learning and data from wearable devices, sensors, and apps. I call the theory and application of statistics for studying one individual's recurrent characteristics and patterns esametry (pronounced "ee-sa-metry"), from isa (pronounced "ee-SA"), the Filipino/Tagalog word for "one".

Prior to Clarify Health, I was a postdoctoral research fellow at the Stanford Prevention Research Center. I'd previously earned my Dr.P.H. in Biostatistics at the University of North Carolina at Chapel Hill, and both my M.P.S. in Applied Statistics and B.A. in Neurobiology / Cognitive Studies at Cornell University. My work in both industry and academia has involved healthcare, pharmaceuticals, clinical trials, survey sampling, nutrition, maternal/child health, global/international health, and health promotion & disease prevention.

I'm interested in causal inference, n-of-1/single-subject studies, Quantified Self, longitudinal analysis, population/public health, minority health (focusing on Asian Americans, in particular Filipinos), the microbiome, and gun violence.

Here's a fun video by my brilliantly witty UNC friends in which I play a singing statistics professor: A Statistical New World (see Videos page for more clips)
