Sabbatical Activities (202223) 
I was on sabbatical from July 1, 2022 to June 30, 2023. You can see what I did below.
M2@CSE (Cleveland, Ohio)
 I attended the Macaulay2 Conference at Cleveland State University.
The conference was the last weekend of May 2022 (a presabbatical trip!).
Here's a group photo:
ICECA (Virtual)
 I attended and gave a talk in the
International Conference on
Enumerative Combinatorics and Applications. This
conference was held from September 67. You can watch the
talk here:
McMaster University (Hamilton, Ontario)
 I gave a talk in our weekly Algebra and Algebraic Geometry Seminar in September.
Calvin Univeristy (Grand Rapids, Michigan)
 I visited Calvin University to give a talk in their biweekly colloquium for undergraduate students. The talk was on September 29, 2022.
 Rather than travel during October and December, I had colleagues visit me! The visitors included Jen Biermann, Enrico Carlini, and Stefano Canino, and resulted in some new projects. Look for them next year.
 I attended the miniworkshop Subvarieties in Projective Spaces and Their Projections at the MFO from Nov 27 to Dec. 3. Here's a group photo
of everyone:
 I attended the Joint Mathematics Meeting in Boston, MA from
Jan. 36, 2023. While there, I gave a
talk in the Special Session on Topological
and Combinatorial Methods in Commutative Algebra.
Here's a photo with me and some of my former postdocs (F. Galetto, J. Biermann, and J. Yang):
While at the meeting, Tai Ha and I recreated a picture of us from 1999 and 2014
Combinatorial Algebra meets Algebraic Combinatorics (Waterloo, ON)
 I attended the Combinatorial Algebra meets
Algebraic Combinatorics annual meeting, which was held in Waterloo this year.
Here's a photo of some of the current and past members of the McMaster Combinatorial Algebraic Geometry group that were at this meeting:
And here's a group photo of the conference:
 More colleagues came to visit in January, including Jen Biermann, Elisa Gorla, Brian Harbourne, and Selvi Kara.

I was a coorganizer of the workshop
Interactions between topological combinatorics
and combinatorial commutative algebra in Banff in April 2023.
Here is is a group photo:
And here is my research group during the workshop (A. Dochtermann, J. Schweig, R. Woodroofe, L. Dao, and me!):
Tulane University (New Orleans, LA)
 I visited Tulane University to give a talk in their biweekly
colloquium. The talk was on April 13, 2023.
While at Tulane, I worked with Tai Ha. Here we are at a Tulane landmark:
Fields Institute (Toronto, ON)
 I attended the
Workshop on Lefschetz Properties in Algebra, Geometry, Topology and Combinatorics which was held at the Fields Institute
on May 1519, 2023.
Here's a group photo of the conference:
And here's my research group from the conference (L. Nicklasson, T. Holleben, me, S. Faridi, S. Cooper)
Sabbatical Wrapup
 My sabbatical is now over as of July 1, 2023. Overall, it was very productive with seven projects finished, and lots of new ideas for going forward. A highlight of
the sabbatical was having three of my students graduate finish their degrees!
