I am a Principal Researcher at Microsoft Research in New York City, where my work in the area of computational social science involves applications of novel computational tools and statistical methods to large-scale social data.
I am also an Adjunct Assistant Professor in Columbia University's Applied Mathematics Department, and I run the Microsoft Research Data Science Summer School to promote diversity in computer science.
I was previously a member of the Social Dynamics group at Yahoo! Research. Before that I received my Ph.D. from Columbia University's Physics Department. See my CV for more on my background and experience.
