Dr. Kteily-O'Sullivan has taught a variety of courses over the years and hopes to be challenged by many more, as the college music curriculum changes with time. She has developed new course sequences and variations of existing ones, including accelerated Music Theory and Aural Skills, an "abbreviated three" semester course sequence (normally completed in four semesters) by freshmen and sophomores who test into this "honors" option, as well as graduate level Problems in Music Theory Pedagogy. She has supervised graduate Music Theory Teaching Assistants and Teaching Fellows as they learn to teach core courses such as Fundamentals, Music Theory I-IV and Aural Skills I-IV and enjoys observing and assisting them in their development as pedagogues.
 
Working actively with the transcription and analysis of improvised jazz and popular music is also a favored pursuit for Dr. Kteily-O'Sullivan; she sings jazz and contemporary music, continues to learn about connecting improvisation with aural skills, and writes analytical and historical research in vocal jazz, with published articles appearing in IAJE Jazz Research Proceedings and in Jazz Educators Journal. She is fascinated by every aspect of music learning and musicianship, especially matters of classroom interaction and the music student's perception of relevance.
 
Dedicating time and effort to academics outside of Music is also important to Dr. Kteily-O'Sullivan. To this end, she has been named as Faculty Fellow in the UNT Transformative Instruction Initiative offered by the Center for Learning Enhancement, Assessment, and Redesign and has secured sizeable grants for course re-design more than once for overhaul of core courses within the Division, improving the student learning outcomes and retention therein.
