clinical research science + quantitative methods

Advancing clinical research through rigorous quantitative science.

I am Reuben Addison, a clinical research scientist with advanced training in study design, Bayesian statistics, biomedical data science, and movement science. My work focuses on generating evidence that can stand up to scientific scrutiny and still be useful to clinical, regulatory, and research teams making real decisions.

01 / About

Clinical research strengthened by rigorous quantitative science.

My work centers on clinical and translational research, with quantitative methods used to strengthen study design, evidence generation, interpretation, and decision-making.

I came into quantitative science through clinical and movement-disorders research. That still shapes how I work. I start with the question a clinician, investigator, or study team needs answered, then build the study design, statistical framework, and computational workflow around that question.

Over the years that has meant designing and analyzing Parkinson's disease studies, building EEG and neuroimaging pipelines, modeling longitudinal treatment and behavioral outcomes, and more recently developing Bayesian clinical-trial and biomedical AI systems. I am especially interested in research where uncertainty, provenance, reproducibility, and interpretation directly affect the strength of the clinical evidence.

I currently lead the Motor Control Lab at DePauw University and work with the Chinese American Biopharmaceutical Society's data-science program. I completed Georgia Tech's M.S. in Analytics, Computational Data Analytics Track (Data Science) in 2026, building on a Ph.D. in Kinesiology focused on motor behavior and neuroscience.

02 / What I do

From evidence synthesis to models that can survive scrutiny.

01 // TRIALS

Clinical Trial Design + Evidence Generation

I build Bayesian and group-sequential trial designs, evaluate power and predictive assurance, test prior sensitivity, and connect design assumptions back to the evidence that supports them.

02 // INFERENCE

Bayesian + Longitudinal Modeling

I use multilevel, mixed-effects, and treatment-response models to carry uncertainty through the analysis rather than burying it behind a single estimate.

03 // AI

Biomedical Machine Learning

I develop CNN, Transformer, ensemble, and interpretable ML pipelines for clinical, physiological, and movement data, with validation designed around the scientific use case.

Movement + Physiological Signals

My research background includes Parkinson's disease, EEG, fMRI, TMS, ECG, motion capture, and markerless pose estimation. I build the preprocessing and quality-control steps that make downstream analysis defensible.

03 / Selected work

Research systems built to be used, checked, and challenged.

A few projects that capture the kind of problems I like: technically demanding, clinically grounded, and easier to trust when the assumptions are visible.

PROJECT 01 2026

OpenTrial

An evidence-grounded Bayesian trial-design engine that curates ClinicalTrials.gov, PubMed, openFDA, and DailyMed into source-cited design inputs. It produces evidence-derived priors, power and assurance analysis, prior-sensitivity checks, and simulation-based design outputs that a study team can trace back to the underlying evidence.

PROJECT 02 ONGOING

KinetiScan

A markerless 3D motion-analysis pipeline that lifts 2D pose into metric 3D coordinates from ordinary camera input. The research focuses on practical validation, numerical parity between research and deployment code, and a path toward accessible movement analysis outside a traditional motion-capture lab.
