Drop-in Advising:

Drop-in Advising is for quick questions that students anticipate will take 10 minutes or fewer to discuss. To access my drop-ins, please follow the CarmenZoon Instructions below. When you enter, you will be placed into a "Waiting Room", and I will pull students into the actual meeting one at a time in the order in which you arrived, as I would with in-person drop-ins.

For Autumn semester (August 24-December 11, 2020), I will hold Drop-ins at the following times:

  • Wednesdays, 8:30-10:30am, US Eastern Time
  • Thursdays, 1:00-3:00pm, US Eastern Time

Any changes to drop-in hours will be announced via email to my assigned advisees.

30-minute Appointments:

In general, I am available for appointments between 8:30am and 4:30pm US Eastern Time on weekdays where the university is open, unless I have another obligation or meeting. You may schedule an appointment with me in one of the following ways:

  • Assigned Advisees: Appointments for any assigned advisees can be scheduled through OnCourse at
    • Choose "Astronomy & Astrophysics Advising Office" for the location, and
    • Choose "Phone/Remote Appointment" for the appointment reason.
