CERIS at Purdue University conducts a Spring ALSTAR Meeting and a Fall NPIRS Conference/ALSTAR Meeting annually. Members, watch your email for announcements.

2020 Fall NPIRS Conference/ALSTAR Meeting POSTPONED

Due to the unprecedented circumstances with the spread of the COVID-19 virus across the United States in 2020, Purdue University has suspended all university-sponsored events involving travel and/or external visitors indefinitely. We are working hard to get back on track and creating new ways to interact once again. We are ironing out details to host a virtual meeting and more details will follow as soon as information becomes available. Stay Tuned!
