The Symposium is a forum for presenting and discussing their astronomical research in an informal setting. All members of the Pasadena astronomy community are invited to attend. Attendance is not limited to scientists. Goodies will be catered..! Format will be ten minute oral talks. The talks are meant to be informal; some levity is encouraged!

IPAC members who wish to make a contributed science presentation are asked to submit a talk title no later than May 21st to Roberta Paladini and Phil Appleton (paladini@ipac.caltech.edu and apple@ipac.caltech.edu). Please use the following title submission form: http://giss.ipac.caltech.edu/meetings/2018/form.html Titles may be inventive. If the topic of your presentation is not immediately apparent from the title, we will contact you for further clarification to aid in making the schedule. Abstracts are not necessary.
