Greg Buzzard, Professor and Head


The math department plays a vital role in the educational and research missions of Purdue; we enroll thousands of students in our classes each year, and our scholarship is well-represented in top academic journals, in partnership with other departments and with industry, and in external funding. We welcome your interest in the department and invite you to explore our website and get to know us better.
Some of you may be interested in reading about the recent changes to foundational mathematics courses.


Fall 2017: Not teaching.


My research in pure math has been primarily in several complex variables and dynamical systems. I've also done work in mathematical biology and uncertainty quantification. For the past several years I've focused on problems arising from sensing and image reconstruction. One project with Dor Ben-Amotz in Purdue Chemistry led to a Raman spectroscopy sensing system that could classify within a specified set of chemicals up to an order of magnitude faster than previous techniques.

Much of my recent work is joint with Charlie Bouman in Purdue ECE; we've developed methods for dynamic sampling and reconstruction with a variety of sensing modalities. We've also developed the foundations of the Plug and Play method for image reconstruction, which gives a principled framework for reconciling sensing data and external information, such as a preferred denoising method, even when one or both of these information sources is not easily cast in an optimization framework.

Publications and software

Here is a CV with a full list of publications and some information about software. Here are links to some of some of my older papers.


I play the violin in the Lafayette Symphony Orchestra and have a black belt in aikido in Lafayette and at Purdue, although playing with two young boys gives me less time for these things than I once had. I have an Erdos number of 3 and a Bacon number of 3.
