About People: DSI Team

Director, Data Science Initiative
Professor of Mathematics

Professor Brock’s work to date has been in the area of geometry and topology, the mathematical study of shapes. He studies coarse features of a space that can determine its structure, using these notions with his collaborators to classify spaces called hyperbolic 3-manifolds. His interests focus on parameter spaces of geometric structures, on surfaces, and on 3-manifolds, and more recently have shifted to the study of finite metric spaces or "point clouds" whose geometry and topology has found new applications in the area of Topological Data Analysis. Understanding the "shape" of data has become a powerful tool for understanding its structure and what meaning can be derived from how data sets are clustered and arranged.

Alden Bumstead
Associate Director, Data Science Initiative

Alden Bumstead comes to the Data Science Initiative via a winding road through literary theory and gender studies, nonprofit consulting, and advocacy for mental health research. This has made her a jack of many trades and master of a few. She has a Ph.D. in American Literature from Duke University and a humanist’s fascination for science.  


Nathaniel Gill
Center Manager, Center for Computational Molecular Biology

Nathaniel manages the operations of the Center and directly supports the Center Director, Center Director of Graduate Studies (DGS), Director of Undergraduate Studies, associated faculty members, undergraduate and PhD students, and post docs by serving as a central point of contact in this multi-disciplinary research and curricular center. Nathaniel manages the grants, physical space, academic appointments, event planning, student programming as well as the website and social media accounts for the Center.

Samuel Watson
Director of Graduate Studies, Data Science Initiative
Tamarkin Assistant Professor, Department of Mathematics

Sam’s research in mathematical probability focuses on the interplay between discrete and continuous random geometry. He studies the convergence of random planar graphs outfitted with natural combinatorial structures to a fractal random surface called Liouville quantum gravity. He has worked on fractional Gaussian fields, which serve to model random behavior in fields as diverse as cosmology, image processing, and agriculture. He has also used his expertise in modeling probabilistic phenomena to contribute to a variety of projects with scientists in other disciplines.
