Program Directors and Mentors


The Career MODE Program (R25GM143298) is led by a robust and experienced set of researchers and academic leaders with complementary, integrated expertise in omics and data science.

We wish to extend our heartleft gratitude to our previous Director and Contact PI, Dr. Andrea Baccarelli.  Currently, Dr. Baccarelli is serving as the Dean of the Faculty at the Harvard T.H. Chan School of Public Health.

Gary Miller, PhD

Dr. Gary Miller has extensive expertise in metabolomics and exposomics. He is a worldwide leader in exposome research, an emerging field that uses omics technology to investigate exposure to exogenous chemicals and their metabolites. Dr. Miller’s laboratory studies metabolomics and exposomics in population-based and experimental research. Dr. Miller serves as Vice Dean of Research and Strategy Development in the Mailman School of Public Health.

Iuliana Ionita-Laza, PhD

Dr. Iuliana Ionita-Laza, holds a PhD in computer science and has specific expertise in development and application of statistical methods for genomic and multi-omic research. Dr. Ionita-Laza’s research in data science emphasizes development of efficient statistical and computational methods for human genetics and statistical genomics. Dr. Ionita-Laza leads the Genomics@Columbia Program, an initiative to bring together an interdisciplinary group of investigators from multiple departments across Columbia University with research expertise in statistical/computational genomics, other omics, computational biology, and biomedical informatics.

Jeanette Stingone, PhD

Dr. Jeanette Stingone,  is an environmental epidemiologist with a focus on perinatal and pediatric health. She conducts research that couples data science techniques with epidemiologic methods to investigate how prenatal and early-life environmental exposures affect health and development throughout childhood and beyond. Currently, she is investigating how machine learning approaches can be used to uncover the combinations of multiple environmental exposures that contribute to disease and disability in children including birth defects, adverse neurodevelopment and early puberty. Dr. Stingone also has a strong interest in the use of collective science initiatives to advance public health research, and works to develop methods and approaches for data harmonization across diverse studies of environmental health.

Linda Valeri, PhD

Linda Valeri

Dr. Linda Valeri,  received her PhD in Biostatistics from Harvard University in 2013, where her dissertation focused on statistical methods for causal mediation analysis. Dr. Valeri is an expert in causal inference with a focus on statistical methods for causal mediation analysis, measurement error, and missing data. She is interested in translating statistical methods in public health to improve our understanding of mental health, environmental determinants of health, and health disparities.


The Career MODE Program is supported by administrators with project management experience with diverse consituencies.

Fernando Luque

Fernando Luque received his Bachelors from the University of Florida and his Masters from CUNY in Anthropology, where he examined  the molecular ecology of S. cerevisiae. Prior to joining Columbia, Fernando's career in fine art was at a gallery dedicated to the scientific examination and authentication of artifacts. At Columbia University, he previously served the Chair and faculty in the department of Environmental Health Sciences. In 2018, he helped spearhead a collaborative pediatric asthma study in post-hurricane Puerto Rico , bridging the gap between clinical professionals, public health students, and an environmental justice organization to address a critical public health challenge. In his current role, Fernando oversees the research development of early-stage investigators through the comprehensive training, networking, and mentorship supported by this NIH/NIGMS funded R25 grant.

Abby Welbourn

Abby Welbourn, Director of Special Projects. Abby has over a decade of experience in academic programming and project and grant management at leading universities. Since 2017, her work at Columbia has led to creating and overseeing the Columbia SHARP (Skills for Health and Research Professionals) Program alongside SHARP Program Director Dr. Andrea Baccarelli.
