Adar’s expertise linking large-scale data to form social networks will inform LIFE-M’s reconstruction of large-scale family networks across generations from tens of millions of vital records and census data. Adar and his lab will contribute to the design and planning of the data linking methodology, including the development of specific techniques for LIFE-M’s link-prediction and multiple-link disambiguation, and implementation of linking methods.


George Alter, Ph.D.

George Alter is a Research Professor at The Inter-university Consortium for Political and Social Research (ICPSR) and the Population Studies Center. Alter has extensive knowledge of the history of the family, demographic history, and fertility transitions in Europe and East Asia and of the effects of childhood experiences on health in old age. Alter’s research experience with data compilation, archiving, and family linking as well as his experience as the director of ICPSR will contribute to all aspects of this project, especially the curation and preservation of the LIFE-M data.


Hoyt Bleakley, Ph.D.

Hoyt Bleakley is an Associate Professor of Economics and a Research Associate Professor at PSC.
