## Sabbatical Activities (2008-09) |

I was on sabbatical from July 1, 2008 to June 30, 2009. You can see what I did below.

**Commutative Algebra and Connections (Lincoln, NE)**

- I attend a conference on Commutative Algebra: Connections with Algebraic Topology and Representation Theory. The conference was held from May 18 - 22, 2008 at the University of Nebraska.

**Research in Teams (BIRS, Banff, AB)**

- With
Chris Francisco and
Tai Ha, I spent May 25 - June 1, 2008 at the
Banff Research Station (BIRS) as part of their Research in Teams
program. We spent the week
Investigating graphs with odd cycles via commutative algebra.

**Macaulay 2 Workshop (Snowbird, Utah)**

- From June 28 - July 3, 2008, I attended the
Macaulay 2 Workshop
at Snowbird, Utah. As part of this workshop, I worked on
some documentation and code for computer algebra package Macaulay 2.
I am currently working with
Andrew Hoefel (Dalhousie) and
Chris Francisco (Oklahoma State) on an edge ideal package.
You can find more about this package on my Research
Page.

**KUMUNU (Lincoln, NE)**

- This year I was able to attend KUMUNU, which was held September 20-21. Before the conference, I visited Chris Francisco; after the conference, I stayed a couple of days to work with Brian Harbourne. Once I get a copy of the conference photo, I'll add it to this webpage.

**AMS Special Session (Vancouver, BC)**

- From Oct. 4 to 5, 2008, I attend the American Mathematical Society Special Session on Hilbert Functions and Free Resolutions. I gave a talk on the connections between graphs and monomial ideals.

**Route 81 (Kingston, ON)**

- This year's Route 81 Conference was
held at Queen's University in Kingston, ON. It was held on Oct. 18. I stayed after the conference to
give a seminar on my work
on fat points.

**Clifford Lecture: Tropical Algebra (New Orleans, LA)**

- From Nov. 4 through 16 I visited Tai Ha at Tulane University in New Orleans. As part of this visit, I gave a talk. Also, I attended this year's Clifford Lecture Series on Tropical Geometry.

**Canadian Mathematical Society Winter Meeting (Ottawa, ON)**

- I attended this year's CMS Winter Meeting (Dec. 5-9) in Ottawa;
I spoke in the
Commutative Algebra and Algebraic Geometry Section. I talked about
nilpotent zero-nonzero patterns.

**Hawaii**

- Nothing math related -- just a vacation (Jan. 2009).

**University of Guelph (Guelph, ON)**

- I was invited by Monica Cojocaru to give a colloquium in the mathematics department at Guelph in February.

**Tulane University (New Orleans, LA)**

- Just in time for Mardi Gras, I visited Tai Ha at New Orleans. While I was there, I gave a colloquium in the department.

** Universita di Catania (Catania, Sicily)**

- I spent two weeks visiting the Universita di Catania to
work with Elena Guardo.
Besides starting a number of projects, I also gave a seminar
on my research (March 2009).

**Universita di Genova (Genoa, Italy)**

- I spent two weeks at the Universita di Genova, working
with Tony Geramita.
I also gave a talk on my work (March 2009).

**Politecnico di Torino (Turin, Italy)**

- When I was visiting Genoa, I went to Turin for
two days to give a talk
and work with Enrico Carlini.

**Redeemer University College (Ancaster, ON)**

- I was invited by Kevin Vander Meulen to give a talk in his abstract algebra class (March 2009).

**Tulane University (New Orleans, LA)**

- Another trip to New Orleans to work with Tai Ha. I was in New Orleans during the first week of April.

**Ontario Combinatorial Workshop (Waterloo, ON)**

- I attened the OCW conference in Waterloo, ON, to learn some more about combinatorics, and to meet some of the local people in the field (May 2009).

**Bridging Mathematics to Mathematics Education (York University, Toronto, ON)**

- I attended a conference on mathematics education at York University (June 2009).
