The proposed theme for the seminar is "Zeta Functions and Cohomology". This 
is meant to be interpreted somewhat loosely, and could include any of the 
following.
   Basics of etale (l-adic) cohomology (from the SGAs, esp. 4 1/2)
   Basics of p-adic (crystalline, rigid) cohomology (work of Berthelot)
   Not-so-basic stuff on either of the above (current work, incl. mine)
   Dwork's proof of rationality of zeta functions
   Fujiwara's theorem on local contributions to the trace formula
   Computational aspects of l-adic and p-adic cohomology (esp. Lauder)
   The de Rham-Witt complex (Lars Hesselholt is the local expert)
   p-adic Hodge theory (a la Fontaine, Colmez, Berger)
   Deninger's hypothetical "arithmetic cohomology"
   Motivic zeta functions (Kapranov, Larsen-Lunts)
We may also run into relevant "purely geometric" topics along the way, e.g.,
log geometry (Martin Olsson's specialty).

More suggestions are welcome!
