So, I took this selfie for #MathCoffeeSelfie because I was heading back from the CMS meeting in Toronto on Sunday, got on my plane, waited a coupla hours, then had my flight canceled. Life is good, but in the scramble to get back home, I forgot to post this on time😬

It's a small roaster in St. Louis, Missouri. They make really good coffee, and they have beautiful design work.

Yuss! I took mine extra early today. Looking forward to a lot of grading and shipping out letters of recommendation. Hoping to do a little research between times too:-)

Went bouldering in Arkansas today, so not much math or selfies, but plenty of coffee!

Life is really good. Yesterday I went to KC to the funeral of my childhood best friend's mom. Sad, but great to see old pals. Then I had some great coffee from Messenger and climbed at Sequence with my nephew. Also had a new idea for my addiction (the Erdős unit distance problem).

Getting ready for a bouldering trip this morning! The only math I did today was thinking about an old Erdős problem during the drive.

His expertise is invaluable. Here is an action shot of him giving me feedback, along with a few other recent snaps. Güero is the blonde, and Taco is the shorthair:-)

During my morning coffee, I snapped this photo, and it's way better than a selfie, so here we are! The math is an updated draft of a note on some funny business with iterated sumset sizes.

Also, it rained a bunch, so I had to change into my crocs. After we arrived at the Platypus, I realized that I was wearing my Perry the Platypus Jibbitz charm:-)

Slightly cheating... this is a selfie from Platypus in St Louis, where a group of us went for a quick cocktail after the first night of the AMS sectional (technically Saturday night).

Life's been really good! We're helping a friend move some furniture down in Arkansas, so we had to stop by Onyx in Rogers, AR.

Took this in Athens before flying back to the states from a conference (Boolean Functions and Applications in Larnaca).

My #mathcoffeeselfie comes early this week, because I'm at a math conference in Cyprus:-)

I have two former student coauthors in town. They're both in PhD programs now. It's been a great weekend:-)

Just put a reminder in my phone to submit an abstract tomorrow... that counts as math, right??

My first #MathCoffeeSelfie in a while. Just got back to Missouri after two months of math traveling: Hanoi (research & Vietnam Polymath Jr REU), Enschede (conference), Taipei (research), and Rochester, NY (StemForAll REU). My shirt is a math shirt, so I think this counts!

Found a super rad spot close to my hotel that does single-origin pourovers. I brought a hand grinder and collapsable cone with me, but it's so nice to try different stuff while traveling:-)

Here's a Sunday #mathcoffeeselfie at my mother-in-law's house. Today I'll be thinking about additive combinatorics in finite fields:-)

I love the math on the walls of the Saldanha station in Lisbon!

No clue what the context is. I love the idea that someone framed a sign with their favorite frequency in the Vienna airport.
