I am a data scientist, with extensive and various experience drawing inference from large data sets. In education research, I work to understand and improve postsecondary student outcomes using the rich, extensive, and complex digital data produced in the course of educating students in the 21st century. In 2011, we launched the E2Coach computer tailored support system, and in 2014, we began the REBUILD project, a college-wide effort to increase the use of evidence-based methods in introductory STEM courses. In 2015, we launched the Digital Innovation Greenhouse, an education technology accelerator within the UM Office of Digital Education and Innovation. In astrophysics, my main research tools have been the Sloan Digital Sky Survey, the Dark Energy Survey, and the simulations which support them both. We use these tools to probe the growth and nature of cosmic structure as well as the expansion history of the Universe, especially through studies of galaxy clusters. I have also studied astrophysical transients as part of the Robotic Optical Transient Search Experiment.

This image, drawn from a network analysis of 127,653,500 connections among 57,752 students, shows the relative degrees of connection for students in the 19 schools and colleges which constitute the University of Michigan. It provides a 30,000 foot overview of the connection and isolation of various groups of students at Michigan. (Drawn from the senior thesis work of UM Computer Science major Kar Epker)

Margaret Hedstrom, PhD, is the Robert M Warner Collegiate Professor of Information in the School of Information and Faculty Associate in the Institute for Social Research.

Prof. Hedstrom’s research centers on the methods, costs, incentives, and implementation of scalable digital curation and archiving services as a core element of the underlying infrastructure for research data management, reproducible research, and data analysis.  She studies the social and technical dimensions digital curation including data sharing behaviors among scientists in different research domains, techniques for automated metadata extraction and user-contributed metadata, requirements for meaningful reuse of numeric, image, and textual data, and long-term preservation of digital information.  Her current research projects span projects involving researchers in environmental science and sustainability, social science, bioinformatics, and materials science.
