Event Type: Journal Club

Talk 1: Jack Heinzel Talk 2: Jackie Hewitt Lunch is provided! The Greek Corner: Pitas, greek salad, rice pilaf, chicken and falafel. Vegetarian, Vegan, DF, and GF options will be available. Email Juliana with any questions or concerns.

All are invited to come hear updates from Rob and others as we begin the new academic year. The meeting and lunch will take place from 12-1pm in the Marlar Lounge. After that, MKI will (weather permitting) walk over to the dome for a group photo, ideally finishing by 1:30pm. The event will be held in person only .
