He is an Associate Editor of International Journal of Hygiene and Environmental Health (IJHEH). He specializes in perinatal and pediatric environmental epidemiology, studying chemical exposures and adverse pregnancy outcomes, child neurodevelopment, obesity and metabolic disorders. He has conducted epidemiologic research on DDT, isoflavones, lead, mercury, cadmium, tobacco smoke, flame retardants, perfluoroalkyl substances, particulate matter, and polycyclic aromatic hydrocarbons. He also has research interest in child health risk reduction through exposure mitigation and (parental) behavior modification since prenatal period.

Research Interests

  • Adverse effects of environmental chemicals on perinatal outcomes and brain development: Identifying potential developmental (neuro) toxicity of metals, persistent organic pollutants, and endocrine disrupting chemicals using epidemiologic studies
  • Reducing chemical exposures in vulnerable fetus and young children: Translating research findings into prevention efforts to reduce environmental chemical exposures including lead, flame retardants, e-waste toxicants, etc.
  • Preterm birth, infant death, and child obesity: Addressing epidemiologic research gaps and preventable causes of adverse pregnancy outcomes, infant morbidity and mortality, and obesity-related disorders
