- Director of TRIPODS Institute for Theoretical Foundations of Data Science at UMass.
- Graduate Program Director for the College.

Prior to UMass, I spent a great couple of years at Microsoft Research (Silicon Valley) and the Information Theory and Applications Center at UCSD. In 2007, I received my Ph.D. from the University of Pennsylvania. During graduate school, I spent a summer at DIMACS and three summers at the Fundamental Maths Department at Bell Labs. In the dim and distant past, I received the Certificate of Advanced Study in Mathematics (2001) and a B.A. in Mathematics (2000) from the University of Cambridge.

Here's text of a short bio, a photo, and a cv.

Since you're here, maybe you'd like to...

- get in contact:
- Mail: College of Information and Computer Sciences, 140 Governor's Drive, University of Massachusetts, Amherst, MA 01003-9264
- Office: Room 334, 140 Governor's Drive (Campus Map and Area Map)
- Email: mcgregor at cs.umass.edu

- submit a paper to a conference where I'm on the PC:
- SODA 2023, PODS 2023, ICDT 2022, and see cv for previous program committees.

- check out material from one of workshops and tutorials I've been organizing:
- Sampling, Sketching, Streaming, Small-Space Optimization: Algorithmic Approaches for Analyzing Large Graphs, KDD (2018). Related tutorials given at ICML (2016) and VLDB (2012).
- Linear Sketching as a Tool for Everything, FOCS Workshop (2017)
- Communication Complexity and Applications II, Banff International Research Station (2017)
- Nexus of Information and Computation Theories, Henri Poincare Institute (2016)
- Towards a Unified Treatment of Dynamic Graphs, Banff International Research Station (2015)
- Algorithms for Large-Scale Graphs, NII Shonan (2014)
- Communication Complexity and Applications, Banff International Research Station (2014)
- Data Streams and Compression (Special Session of CiE 2013),
- STOC 2012 Workshop: Algorithms for Distributed and Streaming Data,
- IITK Workshop on Algorithms for Processing Massive Data Sets (2009),
- DIMACS/DyDAn Workshop on Streaming, Coding, and Compressive Sensing: Unifying Theory and Common Applications to Sparse Signal/Data Analysis and Processing (2009).

- become a Ph.D. student at UMass and work in my group:
- Great! I like the research I do (admittedly I'm biased) but see my papers to make sure you would too. I'm interested in most areas of theory.
- A strong math background is a must for any area of theoretical computer science. A good grasp of probability is particularly useful in my work.
- See here and here for the official application procedure. If you'd like to work with me, mention it in your application and send me an email.
- For general advice about being a Ph.D. student, check out this, this, and everything here.
- Unfortunately, I don't have any funds to support summer interns except for students eligible for the REU program.

But a cloud minus a sailboat

Have no idea what it is."
