the evolution of aviation security

You can listen to me talk about the evolution of aviation security on Wisconsin Public Radio. Norman Gilliland interviewed me for for an hour on the program “University in the Air” that aired on July 30, 2017. It was a lot of fun to chat about aviation security for an hour.

I recorded the program just before I left for an international trip. On my trip, I went through security at four airports on four continents (Chicago O’Hare, Amsterdam, Beijing, and Cairo) and was closely following the different procedures at each airport. It was interesting how different countries and airports tried to achieve similar goals in different ways. Aviation security will continue to evolve and change and will certainly be different a year or two from now. I’ll continue to blog about the evolution of aviation security 🙂

My keynote at the 4th International Workshop on Planning of Emergency Services in Delft

I gave the opening keynote at the 4th International Workshop on Planning of Emergency Services on June 19-20 in the Netherlands at TU Delft. The workshop was organized by Karen Aardal, Theresia van Essen, Pieter van den Berg, and Rob van der Mei. The workshop was a nice way for researchers and practitioners from several countries in Europe to discuss ideas in emergency service planning. Talks were about emergency medical services, defibrillators, and disaster response. The slides from my keynote are posted below. I enjoyed the other keynote given by Jo Røislien, who talked about optimizing air ambulance base locations in Norway and the politics of addressing the policy issues in Norway.

My hosts ensured I enjoyed my time in Delft. Delft is a wonderful place to visit. I took a few pictures from my trip and posted them below.

The Math Behind March Madness

On March 14, 2017 I gave a talk about bracketology, March Madness, and the College Football Playoff in the Discovery Building on the University of Wisconsin-Madison campus. The talk was recorded and can be viewed here or here:

My teaching journey: there and back again

Today I gave the keynote talk for the spring New Educator’s Workshop for teaching assistants at UW-Madison. I’m posting my slides here. My talk was entitled, “My teaching journey: there and back again.”

Abstract. I will talk about my journey from a painfully shy TA to a professor who is comfortable in the classroom and when talking to the media about research on the evening news. I will talk about strategies I used to be effective in the classroom given my strengths (and weaknesses).  Topics include time management, active learning techniques, easy ways to teach with technology, tips for managing student expectations, and things I wish I knew when I was starting to teach.

Punk Rock OR goes to Oberlin College

This week I visited Oberlin College to deliver the Fuzzy Vance Lecture in Mathematics. I was honored to be the 20th Fuzzy Vance lecturer. Each year, Oberlin invites one mathematician (or an operations researcher/fake mathematician in my case!) to visit campus, participate in classes, and give a lecture (the “Fuzzy Vance Lecture”) to the general public.

My evening talk to the public was about my research in emergency medical services and emergency response. My slides and some pictures from my visit are below. I will post my teaching materials on my blog next week.

Oberlin is a small liberal arts college that attracts intelligent students who have eclectic interests. Many students are interested in music, creative writing, and computer science in addition to math. I enjoyed meeting with students when I taught Bob Bosch’s undergraduate course in optimization, which mostly has students from math and computer science.

Bob Bosch and his colleagues in the Oberlin math department were fantastic hosts. They filled me in on the history of the Fuzzy Vance Lecture series, but there was some disagreement about whether Fuzzy Vance was actually fuzzy (nicknamed for fuzzy hair or for another mysterious reason). I was also pleasantly surprised to learn that Oberlin is known for its unusual albino squirrel population. I am a fan of campus squirrels: the squirrels at my alma mater have had an interesting history.

Here are some memories from my visit.

Rock and Roll Hall of Fame advertisements were everywhere in Cleveland. I was thrilled to be able to visit the museum during my visit.

a journey to the German OR Society Conference

Earlier in September, I gave a semi-plenary at the 2014 German OR Conference in Aachen, Germany. It was a wonderful conference and experience that will inspire at least another blog post or two. The German OR Society and Marco LĂĽbbecke were wonderful hosts and conference organizers. There were more than 850 attendees, 500 talks, and an impressive group of plenary and semi-plenary talks.

Earlier I blogged about Mike Trick’s plenary talk on Major League Baseball scheduling and analytics that opened up the conference. I’m finally getting around to blogging about my talk on emergency medical services. For another take, see Mike Trick’s blog post about my talk. I learned a lot by giving the talk and talking to German researchers. Emergency medical services are operated in different ways in different parts of the world. It was refreshing to talk to other researchers who are looking at healthcare delivery issues from a different perspective than we have in the United States. It was also fun to catch up with two of my favorite bloggers (Mike Trick and and Marc-Andre Carle) at social events and meet some Punk Rock OR readers from across the pond.

I posted the slides to my talk below.

I took a few pictures from the conference and from Aachen that capture some of the highlights of the trip.

The conference bags were pretty snazzy.

how to find a football team’s best mix of pass and run plays using game theory

This is my third and final post in my series of football analytics slidecasts. After this one, just enjoy the Superbowl. My first two posts are here and here.

This slidecast illustrates how to find

  • the offensive team’s best mix of run and pass plays, and
  • the defensive team’s best mix of run and pass defenses.
The best mix is, of course, a mixed strategy. We use a game theory to identify the best mix (a Nash equilibrium) for a simultaneous, perfect information, zero-sum game.

What is a football team’s best mix of running and passing plays?
