There are many ways to contribute to research, and I've gathered a few opportunities below! I'll try and keep them updated as I receive word of more, but I primarily track them as individual lab directors create recruitment posts on Twitter (these are not the only places of course). Below you'll find (a) PhD Programs in HCI (soon) Academic Summer Research Programs (soon) Industry Full Time Positions and (soon) Industry Internships. There are plenty of other opportunities - such as doing independent research while being a student or working as a research assistant in a lab.
Note that the tags I've assigned may not be a strict representation of the posting.
