Yeah, domestic applicant. Notified through email on both. From Duke I heard from the department's graduate office and from Penn State I heard from a professor I've been in contact with throughout the application process.
Applied to: Duke (PhD), Penn State (MS w/ PhD intent), NC State (PhD), Hopkins (PhD), VA Tech (PhD), and Illinois (MS w/ PhD intent) for environmental. I haven't heard anything official on admittance from anywhere yet, but have visit offers from Duke and Penn State.
