"Matroid strata in the moduli space of pointed curves"
Abstract: Any curve of positive genus g can be embedded in a projective space by its canonical map, as long as the curve is not hyperelliptic. This way, any n distinct points on the curve define a realizable matroid on n points of rank at most This can be used to define natural matroid strata in the moduli space M_g,n as well as a tropical analogue.

„Chow polynomials of matroids“
Abstract: Chow polynomials of matroids are the Hilbert series of their Chow ring. We will start with reviewing the history and the importance of these concepts. We then discuss other polynomials motivated from general poset theory and from number theorey, and show how these related concepts can be unified using ab- and cd-indices of finite bounded graded posets. This work is partially joint work with Galen Dorpalen-Barry, Elena Hoster, and Josh Maglione.
