International Organ Competition ‘Pierre de Manchicourt’ (Béthune and Saint-Omer), second prize in the 2015 Arthur Poister Scholarship Competition, third prize at the VIII Musashino International Organ Competition (Tokyo), and Laureate, Third Place, and recital prizes as the youngest finalist in the VIII Mikael Tariverdiev International Organ Competition (Kaliningrad). She is also a member of The Diapason’s inaugural "20 under 30" class of 2015, recognising "superior accomplishments, leadership, creativity, and innovative thinking". 

Katelyn's recordings, Evocations (2017), on the historic 1936 Aeolian-Skinner at the Church of the Advent, Boston, and Inspirations (2018), sponsored by the Andover Organ Company for its seventieth anniversary, appear on the Pro Organo label. Both have been enthusiastically received by the press, with Katelyn's playing in Evocations called "masterful in execution, in turns majestic in its musical power and deeply moving", and the recording "a must […] for organ aficionados" (Fanfare). The American Organist wrote that Inspirations is "a wonderful study in programming, interpretation, and registration" in which ‘"artist, instrument, repertoire, and production come together in one 76-minute-long triumph". Her interviews and performances have been broadcast on American Public Media’s Pipedreams, WXXI’s With Heart and Voice, Radio Russia, Radio VM’s Récit au grand orgue (Québec), and Radio Présence (Toulouse). 

 

Between travels for performances, Katelyn is based in the United States and the United Kingdom as a PhD candidate at the University of Cambridge’s Centre for Music and Science, funded by an ESRC Doctoral Training Partnership 1+3 studentship and a UKRI bursary. Her investigations into the intersections between musicians' interpretations, bodies, backgrounds, and instruments stem directly from her pedagogy and performance, with articles related to her research appearing in both peer-reviewed and trade journals, including Transactions of the International Society for Music Information Retrieval, the Journal of Hand Therapy, and Choir & Organ. Katelyn holds an MPhil in Music from Cambridge, a Master of Arts in organ from the Staatliche Hochschule für Musik und Darstellende Kunst Stuttgart, supported by a German Academic Exchange Scholarship (DAAD), and, as a J. William Fulbright Study/Research grantee, studied en perfectionnement at the Conservatoire à rayonnement régional de Toulouse with Michel Bouvard and Jan Willem Jansen. Her double bachelor’s degrees in organ performance and French, with minors in music history and historical performance (fortepiano), are from Oberlin College & Conservatory. While at Oberlin, she tutored music theory, received the Selby Harlan Houston Prize for work in organ and music theory, and was inducted into Pi Kappa Lambda, the national music honors society. Further support has included a 2026 Royal College of Organists United Grand Lodge of England bursary, the 2015 McClelland Community Music Foundation Scholarship, and the 2013 M. Louise Miller Scholarship. Her teachers have included Ludger Lohmann, Olivier Latry, Hans-Ola Ericsson, James David Christie, Marie-Louise Langlais, Ray Cornils, and Abbey Hallberg-Siegfried.​

Equally sought-after for her teaching as for her playing, Katelyn teaches privately, coaches players for international competitions and diplomas, and is a regular faculty member at academies that have included St Andrews University Organ Week (Scotland), the McGill Student Organ Academy (Canada), the Oberlin Summer Organ Academy, and more than a dozen AGO Pipe Organ Encounters. At Cambridge, she has supervised undergraduates in music psychology and performance studies and coordinates educational events and lessons for the University-wide Organ Scholars Forum. A Certificate in Advanced Occupational Ergonomics from Colorado State University underpins key aspects of her pedagogy, and she has been invited to give dozens of classes on healthy practice techniques, performance-impacting injury prevention and recovery, interpretation, and sacred music in the United States, Canada, and the United Kingdom. Katelyn receives frequent invitations to adjudicate international playing competitions, most recently the 2027 Canadian International Organ Competition (preliminary round), the 2027 Miami International Organ Competition (USA), the 2026 Sydney Organ Competition (Australia), the 2025 Concours international pour orgue de Saint-Maurice (Switzerland), and the 2024 IAO–RCO Organ Playing Competition (UK).
