I am a Professor of
Computer and Information Science at
Fordham University.
I began my career in 1985 with AT&T Bell Labs, where I remained until I joined
Fordham in 2004. I started as a software engineer for private telephone switching systems,
moved on to expert system development to support central office switches, and then
spent my final five years at AT&T applying machine learning methods to business and
marketing problems.
I received my B.S. degree in
Computer Science from
Cornell University, M.S. degree in
Computer Science from
Stanford University, and doctorate in
Computer Science from
Rutgers University.
My research relates to machine learning and data mining and
I have over ninety research publications in these areas.
Up until 2010 my research focused on handling the real-world issues that make learning
difficult (e.g., class imbalance). From 2010 until 2019 my research focused on
WIreless Sensor Data Mining (WISDM) and my
WISDM research group, with support
from the National Science Foundation,
developed a smartphone app that used accelerometer data to identify a user's
physical activity in real-time (this work began before the first Fitbit was
released). This work was subsequently extended to include smartwatches, to track dozens
of activities, and to also perform (behavioral) biometrics.
Over the past couple of years my research has shifted to Educational Data Mining (EDM,)
with the goal of improving education using a data-intensive approach. Students who are
interested in this topic are welcome to join my EDM Lab, which I co-direct with
Dr. Daniel Leeds.

Fun Facts
I can trace my academic lineage back to (and past)
Copernicus
(the hard lifting was done by my advisor,
Haym Hirsh).
My Erdös number is 2:
Paul Erdös to
Frank Hsu to
Gary Weiss.
My Erdös-Bacon number, on the other hand, is infinite, and is likely to remain so.

New York Mets pitching coach (quoted
in New York Times, Jun 13, 2004).
