This week we have Michael Zantedeschi, currently a postdoc at the Tsung-Dao Lee Institute, Shanghai Jiao Tong University (in the group of Luca Visinelli), visiting us for a couple of days. Michael is actually not new to Trento, having been an undergrad here (although he arrived just after I finished my undergrad, so we never overlapped). While we aren’t directly working together (yet), we will be brainstorming ideas related to screened dark energy, as well as the mysterious cosmological constant. Welcome Michael!
