Prospective Students

Our lab is always looking for highly motivated, extremely curious students, with interesting and diverse backgrounds. After reading some of our papers, and looking at some of our projects, where do you see yourself?

  • Do you have serious hardware hacking skills? Are you a software guru?
  • Maybe you are interested in handling the massive amounts of lossy data these systems gather in an elegant way?
  • Perchance you think that all of this falls apart unless we study the human factors, and the sociological impact of trillions of always on devices interacting with us?
  • Or maybe you just really like to build things and see those things have an impact.

If you are any of these people, we might be interested in working with you as a graduate, or undergraduate student.

Before you contact us, It is highly recommended you read this advice , and this advice. Make sure to apply to Northwestern Engineering, and we can talk about working together. If you are already at Northwestern as an undergraduate or graduate student, email Prof Hester to schedule a time to talk in his office.

Prof Hester (a Native Hawaiian) is especially interested in engaging Native and Indigenous students and researchers in Computer Science and Engineering. Please reach out.
