Scholarly Interest:

Dr. Ryckman is a perinatal epidemiologist with expertise in statistics, genetics, and metabolomics. Her research has applied a variety of statistical methodologies including the use of genetic risk scores, predictive modeling, and meta-analysis for analyzing pregnancy complications including preeclampsia, gestational diabetes, and preterm birth. She has established a successful research program that includes several national and international data sources and a large repository of biologic specimens. Her current work focuses broadly on two areas:

1. neonatal morbidity and mortality and
2. maternal morbidity and mortality.

An ongoing project is to use targeted metabolic profiling to predict major neonatal morbidity and mortality in babies born less than 32 weeks gestation. She is also examining how neonatal metabolic profiles can predict neurodevelopmental, spatial and numerical skills and respiratory and cardiovascular outcomes in babies born preterm. Her current work on maternal morbidity and mortality has been focused on four areas:

1. improving data measurement and reporting,
2. identifying obstetrical and health system risk factors,
3. examining social determinants and disparities including maternal mental health, and
4. engaging community and stakeholder perspectives in implementation of interventions.
