DESCRIPTION:Sam Molcho (ETHZ)\nThe cohomology ring of the moduli space of 
 curves contains two families of classes with different geometric origins: 
 one comes from the universal Jacobian and Brill-Noether theory\, and the o
 ther from the moduli space of stable maps and Gromov-Witten theory. After 
 reviewing their construction\, I will explain how new ideas from logarithm
 ic geometry connect these classes\, and discuss how the connection allows 
 us to explicitly calculate them in the tautological ring\, in terms of its
  standard generators. Time permitting\, I will indicate the implications t
 hese calculations have for the study of relations in the tautological ring
 . The talk will draw from several joint works and some work in progress\, 
 carried out with Holmes-Pandharipande-Pixton-Schmitt\, Abreu-Pagani\, Rang
 anthan\, and Wise.  \n
