Joon Ha

Joon Ha is an Associate Professor in the Department of Mathematics at Howard University. His research applies mathematical modeling and statistical analysis to diabetes pathophysiology, focusing on glucose metabolism, insulin resistance, and early diabetes prediction using oral glucose tolerance test (OGTT) dynamics.

His research focuses on mathematical modeling of glucose-insulin dynamics, early diabetes detection strategies, ethnic disparities in diabetes pathogenesis, and machine learning applications for metabolic health prediction.

Publications demonstrate extensive work on refining OGTT interpretation (particularly 1-hour glucose thresholds), developing mathematical models of insulin sensitivity/secretion, and validating risk prediction models across diverse populations, with recent emphasis on machine learning and ethnic-specific diagnostic criteria.
