Statistical Analysis Core Faculty Lead
Dr. Niko Kaciroti, PhD
Research Scientist
Center for Human Growth and Development

Dr. Kaciroti’s research focuses on using Bayesian modeling techniques for analyzing longitudinal data from randomized clinical trials with missing data as well as for modeling nonlinear and dynamic models in a multilevel setting. His applied research is related to the effect of iron deficiency on brain, behavior and development; obesity; managing chronic disease; hypertension and cardiovascular diseases; and emotion regulation as complex systems in preschoolers.

Harlan McCaffery, MS
Statistician Intermediate
Center for Human Growth and Development

Mr. McCaffery earned his MS in Biostatistics with concentration in Statistical Methods and Practice from Northwestern University in 2018.  He has experience with longitudinal data analysis, survival analysis, and statistical programming. With his background in anthropology and archaeology, he is familiar with the application of statistical methods to the social sciences, and has been published in the archaeological journal American Antiquity. He is also interested in methods for handling missing data and genomics.
