I am a data scientist. Data science is an emerging field commonly described as “the practice of deriving valuable insights from data,” and this thread runs through all of my work. My scholarly contributions have come in five main areas:

Subfields of interest to me include network science, applied statistics, sabermetrics, sports analytics, statistical modeling, analysis of algorithms, combinatorial optimization, data visualization, graph theory, and combinatorics. My Erdös number is 3, as I have co-authored a paper with Amotz Bar-Noy, who has co-authored a paper with Noga Alon, who has co-authored a paper with Paul Erdös.

My background is academically diverse, in that my undergraduate degree is in economics (my first declared major was English), my doctorate is in mathematics, my thesis advisor is in computer science, and my professional experience is in statistics. As such, my research tends to be interdisciplinary, with an emphasis on applying available techniques from any discpline to address the question of interest.

In 2012, I completed my Ph.D. in Mathematics at the Graduate Center of the City University of New York, where my advisor was Amotz Bar-Noy, also of Brooklyn College. Previously, I earned an M.A. in Applied Mathematics from the University of California, San Diego, and a B.A. in Economics from Wesleyan University.

In 2019, I won the Significant Contributor Award from the Section on Statistics in Sports of the American Statistical Association.

Analyzing Baseball Data with R cover

Analyzing Baseball Data with R, 2nd edition

Analyzing Baseball Data with R, 2nd Edition introduces R to sabermetricians, baseball enthusiasts, and students interested in exploring the richness of baseball data. It equips you with the necessary skills and software tools to perform all the analysis steps, from importing the data to transforming them into an appropriate format to visualizing the data via graphs to performing a statistical analysis.

Modern Data Science with R

Contemporary data science uses both statistical modeling and computer programming to extract meaning from data. It requires a tight integration of knowledge from statistics, computer science, mathematics, and a domain of application. This book, which is intended for readers with some background in statistics and modest prior experience with coding, helps them develop and practice the appropriate skills to tackle complex data science projects. Most of the examples are done in R, but SQL, Python, and other cutting-edge tools are discussed as well.

The Sabermetric Revolution

Since leaving the Mets, I’ve written a book, entitled The Sabermetric Revolution: Assessing the Growth of Analytics in Baseball, with leading sports economist Andrew Zimbalist. We examine the evolution of sabermetrics in baseball and other sports since the publication of Moneyball, summarize the current state of sabermetric thinking, and address the question of whether there is any evidence that sabermetrics has actually worked. The book will be published by the University of Pennsylvania Press and is scheduled for a December 2013 release.

DataCamp courses

I am currently collaborating on a introductory Statistics with R sequence of courses for DataCamp, an interactive platform to learn R and data science. Mine Cetinkaya-Rundel (Duke), Andrew Bray (Reed), and Jo Hardin (Pomona) are working with me on these courses. We are horrified by the recent sexual harassment scandal at DataCamp and the ensuing coverup.

ETL packages for R

etl is an R package to facilitate Extract - Transform - Load (ETL) operations for medium data. The end result is generally a populated SQL database, but the user interaction takes place solely within R.
