Summary

My research has been primarily focused in using Bayesian methods to create innovative model-based clustering techniques to address data complexities found in large, heterogeneous populations. These methods were generated as a result of my collaborative research interests in maternal health, nutritional epidemiology, psychological health, public health policy, and health disparities.
