CS Department Student Info

Computer science undergraduate students are supported by multiple people currently. Collectively we answer emails and meet with students or faculty to answer questions related to computer science undergraduate programs. Lyn, Abby and Joanne are points of contact for declaring a CS major/minor. You can reach us with questions or to make an appointment through advising -at- cs.jhu.edu. Kelly is our department liason from the Office of Engineering Advising. Our pronouns are she/her/hers. See below for office hour details.

  • Joanne Selinski, Director of Undergraduate Studies & Associate Head for Education (CS faculty)
  • Lyn Doan, Sr. Academic Program Coordinator (CS staff)
  • Abby Fanara, Sr. Academic Program Coordinator (CS staff)
  • Kelly Barnhart, Academic Adviser (WSE staff)

Declared CS second majors and minors in need of CS-specific faculty mentoring are welcome to email Prof. Joanne Selinski and Prof. Sara More jointly with your questions or for an appointment.

Students interested in declaring a CS major or minor will need to

  1. Submit a major/minor change/declaration request form on SIS (“Registration” > “Online Forms” > “Add a Major or Minor")
  2. If you are changing your first major from KSAS to WSE, you will then need to meet with Engineering Advising to get a new academic advisor.
  3. Complete a 4-year plan to demonstrate how you will meet the requirements alongside any other majors/minors you have using one of the CS major worksheets in the first section of our majors advising page, the CS minor worksheet
  4. Meet with one of Joanne, Lyn or Abby to review your plan and get departmental approval.
  5. Your professional academic advisor will then need to provide the final approval step online. Contact them if there seems to be a delay after meeting with one of us.

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.
