My research work focuses on data science, database management, bigdata analytics, and risk prediction frameworks using machine learning algorithms and high-performance computing environments. Specific fileds of interest include longitudinal EMR data analytics using statistical, machine learning, ensemble learning, transfer learning, and federated learning algorithms (e.g., cox regression, support vector machines, decision trees - eXtreme Gradient Boosting: XGBoost, random survival forests, RSF and neural networks).
I have over 25 years of professional experience working in several data-driven research projects (such as Real Time clinical data analytics, Children’s Health Exposure Analysis Resource (CHEAR), 'Emory Health and Exposome Research Center: Understanding Lifetime Exposures (HERCULES)', Tennessee's Longitudinal Data System (TLDS), Kennesaw's Teacher Quality Partnership, (TQP)), and built custom databases, software applications, and data visualization portals/dash boards. I have hands-on working knowledge with Emory healthcare data sources (such as Cerner’s Electronic Medical Records (EMR), EPIC’s Electronic Health Records (EHR) database systems, adult cardiac surgical database and clinical data warehouse).
My recent research projects include building institutional biobank for CURE COVID-19 biospecimens and metadata prospective cohort and developing novel frameworks to predict the risk of readmission after coronary artery bypass grafting (CABG). My current collaborative research efforts focus on: 1) developing scalable, portable, and reproducible machine learning powered frameworks - via feature engineering, hybrid feature selection, survival analysis and ensemble learning to accurately predict the risk factors for (a) 'Failure to Rescue' after CABG, and (b) readmission after CABG; 2) developing personalized HIV testing frequency recommendations based on AI-powered recommendation engine, 3) analyzing EHR data to evaluate differences in the utilization of outpatient rehabilitation services among young adults with stroke (YAS) between the ages 21-60 years old, and 4) analyzing EHR data to develop and pilot a telehealth ‘Health-related social needs (HRSN)’ screening and referral uptake intervention in a population with uncontrolled diabetes..
