CS Department Student Info

Computer science undergraduate students are supported by three people currently. Collectively we answer emails and meet with students or faculty to answer questions related to computer science undergraduate programs. Lyn and Joanne are also points of contact for declaring a CS major/minor. See below for office hour details. You can reach all of us at once with questions or to make an appointment through advising -at- cs.jhu.edu. Our pronouns are she/her/hers.

  • Joanne Selinski, Director of Undergraduate Studies (CS faculty)
  • Lyn Doan, Academic Program Coordinator (CS staff)
  • Kelly (Culotta) Barnhart, Academic Adviser (WSE staff)

Please visit the links below and to the left for information regarding academics, courses and activities in the department. Feel free to drop by office hours with questions or to simply chat about anything going on.

Office Hours

  • Joanne's hours will be drop-in (no appointment needed), or by appointment request.
  • Lyn's hours will be by appointment, scheduled in advance on this calendar site. The calendar confirmation will contain the Zoom info.

  • If attending drop-in office hours in person, please wait quietly in the hallway until it is your turn. If on zoom, you'll join a virtual waiting room and be invited in when it's your turn.
  • Students interested in declaring a CS major or minor will need to
    1. Submit a major/minor change/declaration request form on SIS
    2. Complete a 4-year plan to demonstrate how you will meet the requirements alongside any other majors/minors you have using the CS major worksheet (majors only) or the uCredit platform (majors/minors)
    3. Meet with Joanne or Lyn to review your plan. If approved, we will assign you a faculty adviser for the program.
