Alden Bumstead
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.

Samuel Watson
Samuel
S.
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.
