His primary affiliation is with the UCLA OB GYN division, where he focuses on fetal physiology and pregnancy complications.

His research spans fetal hemodynamics, metabolomics in gestational diabetes and preterm birth, respiratory control mechanisms in neonates, and maternal-fetal interactions in high-risk pregnancies, including those complicated by HIV and congenital heart disease. Key methodologies include animal models (e.g., fetal sheep), metabolomic profiling, and clinical outcome analysis.

His publications highlight collaborations with the IMPAACT 1077BF/1077FF PROMISE Study Team, American Heart Association, and interdisciplinary partners. Articles focus on fetal programming, pregnancy biomarkers, and medical guidelines for managing complex maternal conditions.
