## Spring 2023

APAM is happy to announce the inaugural **2023 Spring APAM Graduate Student Research Symposium**, which will take place on **Friday, April 21, 2023 from 10:00 AM - 5:30 PM**. This research symposium replaces and condenses the former spring semester Friday student research seminars into one big event.

**Event structure:**

There will be 3 sessions with talks from students from each APAM PhD program accompanied by a coffee break, lunch break, and a dinner reception / APAM Friday at the end with awards including cash prizes of $200 for the best presentation from each session. All APAM students (grad & undergrad), postdocs, and faculty are invited (and expected) to attend the event!

Please mark the date in your calendars and plan accordingly so you can attend most if not all of the event! We are hoping the whole department will attend! View a tentative schedule as well as register for the event HERE

**Call for abstracts: **

PhD students: please fill out this form to sign up to give a talk (see form for details). 4th year students are strongly encouraged to sign up but we will accept sign ups from APAM PhD students in their 3rd year and above. The deadline to sign up for talks is Friday, March 31, 2023. If you have any questions or concerns you can email the grad student organizers at [email protected].
