Research Topics

Dr Sundaram’s research is at the intersection of statistical methods and public health. Her interests include development of statistical methods for survival outcomes, especially multivariate survival outcomes and recurrent events, joint modeling of longitudinal data and survival data and hierarchical data with applications to reproductive outcomes, pediatrics and obstetrics. She is also interested in developing statistical methods for assessing the effects of chemical mixtures on health outcomes, especially pertaining to reproductive and child development, as well as methods for analyzing exposome type of data. Over past few years, she has worked to develop statistical methods aimed at building biologically meaningful models to better assess fecundity and fertility, with a focus on building individualized risk prediction for conception delay and infertility, issues of considerable interest due to the changing profile of couples attempting pregnancy for the first time. She is also currently interested in contributing to better guidelines for labor management in pregnant women by developing methods to address labor progression and by assessing labor arrests and other factors leading to medical intervention.Additionally, she is working on Machine Learning methods for analyzing data coming from continuous monitoring devices, like actigraphy.
