Nina points out the Submodularity Workshop March 19-20 next week at Georgia Tech. Many people want to make Submodularity the new Convexity in machine learning, and it certainly seems worth exploring.
Sara Olson also points out a tenured faculty position at IMT Lucca with a deadline of May 15th. Lucca happens to be the ancestral home of 1/4 of my heritage 🙂
