Sheryl's primary research focus is understanding the relative contribution of social factors and environmental exposures on chronic disease. She has worked extensively in the elementary school setting on developing surveillance methods and educational programs for childhood asthma, understanding the role of lead exposure in educational outcomes, and analyzing the role of social culture and indoor environmental quality and the health and performance of students and teachers. She has active collaborations with exposure scientists to develop refined exposure assessment models in community and agricultural settings in studies of childhood and occupational respiratory disease. Her current methodological work focuses on application of novel approaches to understand environmental pollutant mixtures in community-based studies. Sheryl is the epidemiology concentration lead at the ColoradoSPH at CSU.
