My schedule

I am a professor in the Mathematics Department at Southern Connecticut State University.

I am the lead developer/maintainer of the Guava package for the GAP computer algebra system. GAP is designed as a computational aid for Group Theory and Algebra, it has many add-on packages, among them is Guava which performs computations related to error-correcting codes.

I am Co-Principal Investigator on the NSF-sponsored Pathways to Academic Excellence (PAcE) grant. The PAcE program provides nearly $600,000.00 for scholarships to SCSU for students majoring in STEM disciplines. See www.southernct.edu/academics/schools/arts/cems/pace/ for more information.

I received my PhD degree in Mathematics from the University of Illinois
at Chicago.

My areas of research are in the theory of error-correcting codes,
and Combinatorics.

My advisor was Vera Pless.

Here are some items on which I've been working:

- A presentation on my solar pizza oven that I gave at Choate.
- A presentation on squigonometry at the Fall GeoGebra conference at SCSU.
- Along with Vince Ferlini of Keene State College, I am coordinating the NESMAA Collegiate Math Competition.
- A calendar for 2015 printed on plaits that can be woven together to form a rhombic dodecahedron
- We invited Mathematician/Sculptor George Hart to campus on 10/26/2012. George gave a lecture in the PAcE Seminar and then conducted a workshop with Southern's Math Club where they constructed one of George's sculptural designs: Cardboard Conglobulation.
- My presentation for CAMPY on cryptography.
- A truss with fractional dimension.
- Using honeydew melons to teach the volume element in spherical coordinates. (Students repeat the mantra "Rho-squared, sine phi, dee rho dee theta dee phi" while munching on the delicious volume elements.)
- Along with Ross Gingrich I am coaching the SCSU Putnam Competition team.
- The slides for my talk at the fall 2009 NES/MAA meeting --
*Differential Equations with a Fractal Character*. - The slides for my expository talk on Coding theory.
- The slides for my expository talk on Brun's Sieve -- a nice generalization of the sieve of Eratosthenes that solves some notable number theoretic problems.
- The split weight enumerator of the Golay code, partitioned with respect to the supports of two disjoint minimum weight vectors, as a VRML model. (This version is non-rotating.)
- Version 4.2 of HTMX (a tool that helps you include equations in web documents) is ready.
- I am converting an Internal Combustion Engine (ICE) car to a Battery Electric Vehicle (BEV). Find out more at the EV discussion list.
- A page using VRML models to show that
the group of symmetries
of the dodecahedron is A
_{5}. - I've created a Geography study site consisting of a bunch of blank maps of the countries of the world. These are image maps with links to labelled maps and flags (courtesy of the CIA's World Factbook) for the countries.
- My presentation at the 16th annual CSU Academic Computing Conference.
- I'm the Puzzle Editor for SCSU's Math Department Alumni Newsletter.
- DRAFT of "Decoding the Golay code by hand", an on-line math paper.
- Boy's Surface
- A Small Puzzle
- Animations!!!
- A dictionary of combinatorics.
- My Cat-tree/sculpture hobby.
- My hotlist.
