  • Björn Sandstede

    Director, Data Science Initiative, Royce Family Professor of Teaching Excellence and Professor of Applied Mathematics


    Björn Sandstede is a Professor of Applied Mathematics, and currently a Royce Family Professor of Teaching Excellence, at Brown University. His research focuses on dynamical systems, data science, and applications to biological systems. Sandstede received his undergraduate degree from the University of Heidelberg and his PhD from the University in Stuttgart. Before coming to Brown in 2008, he... Read More

  • Sohini Ramachandran

    Director of Center for Computational Molecular Biology, Associate Professor of Ecology and Evolutionary Biology, Associate Professor of Computer Science


    Professor Ramachandran addresses problems in evolutionary theory and human population genetics. The Ramachandran Lab uses mathematical modeling, applied statistical methods, and computer simulations to make inferences about evolutionary history from present-day samples of genomes. They particularly focus on developing new methods for identifying adaptive genomic elements, characterizing... Read More

  • Joseph Hogan

    Deputy Director, Data Science Initiative, Carole and Lawrence Sirovich Professor of Public Health , Chair and Professor of Biostatistics

    Professor Hogan's research concerns statistical methods for missing data, causal inference, and sensitivity analysis, especially in HIV/AIDS. Much of his recent work focuses on HIV in sub-Saharan Africa. Current projects include the development of methods for analysis of large-scale observational data, optimizing the use of limited information for clinical monitoring of patients on antiviral...

  • Daniel Weinreich

    Interim Director, Center for Computational Molecular Biology, Director of Graduate Studies, Center for Computational Molecular Biology, Associate Professor of Biology


    Professor Weinreich uses complementary theoretical and experimental methods to study how genetic novelty fuels evolution by natural selection. Current work in the group focuses on:

    • the causes and consequences of mutational interactions in the bacterial drug resistance gene TEM-1 ß-lactamase
    • the evolution of mutational robustness
    • evolution in... Read More

  • Eli Upfal

    Deputy Director, Data Science Initiative, Professor of Computer Science


  • Alden Bumstead

    Associate Director

    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.  

  • Daniel Potter

    Director of Industry Relations


    Dan Potter is Director of Industry Relations for the Brown Data Science Initiative, and also an Adjunct Associate Professor of Computer Science.  He regularly teaches courses on Scientific Computing and Data Science. In addition to his responsibilities at Brown, Dr. Potter has been a Senior Advisor to Disciplined Alpha LLC since the firm’s inception in January 2013. In 2016 he became the... Read More

  • Samuel Watson

    Director of Graduate Studies

    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... Read More

  • Administrative Assistant


    A Providence native, Meg comes from a background in media arts, visual design and event planning, earning her BA from Emerson College. She worked previously at the Brown/NSF Institute for Computational and Experimental Research in Mathematics (ICERM), among other higher education institutions. She continues to have a passion for learning and soon plans to finish her Master's of Interior... Read More


  • Alice Paul

    Postdoctoral Research Associate

    Alice Paul completed her Ph.D. in the Department of Operations Research and Information Engineering at Cornell University, advised by Professor David Williamson. Her research focuses on the design and analysis of algorithms.  Alice's thesis centered around developing efficient, data-driven algorithms for revenue management problems under probabilistic customer choice models. Additionally,... Read More

  • Ksenia Kyzyurova

    Postdoctoral Research Associate

    Ksenia has graduated with a Ph.D. in Statistical Science from Duke University in 2017, where she wrote her thesis "On Uncertainty Quantification for Systems of Computer Models". Before coming to Duke, she received a BS and a MS, both in Applied Mathematics and Computer Science, from ITMO University in St.-Petersburg, Russia.

  • Sarah Brown

    Postdoctoral Research Associate

    Sarah Brown is a Postdoctoral Research Associate in the Data Science Initiative. She earned her PhD in 2016, MS in 2014, and BS in 2011 all in Electrical Engineering at Northeastern University.  Prior to joining Brown, she was a Chancellor's Postdoctoral Fellow at the University of California Berkeley in Computer Science and a member of the Algorithmic Fairness and Opacity Working group. Dr...
