Child Amplification Laboratory Members

Principal Investigators

Dr. Susan Scollie is a Principal Investigator at the National Centre for Audiology and an Assistant Professor at the University of Western Ontario in London, Ontario, Canada. Together with her collaborators, she developed the recently released DSL m[i/o] algorithm for hearing aid fitting. Her current research focuses on the evaluation of novel digital signal processing for high frequency hearing losses, pediatric outcome measurement, and noise management for children.

Dr. Richard C. Seewald is a Principal Investigator at the National Centre for Audiology in London, Ontario, Canada and holds the Canada Research Chair in Childhood Hearing. He is also a Professor in the School of Communication Sciences and Disorders, Faculty of Health Sciences, University of Western Ontario. For the past 25 years, Dr. Seewald's work has been focused on issues that pertain to the selection fitting of amplification in infants and young children. He is known internationally for his work in developing the Desired Sensation Level (DSL) Method for pediatric hearing instrument fitting. He has been honoured with several awards including the Career Award from the Canadian Academy of Audiology and the International Award of the American Academy of Audiology.

Research Audiologists and Doctoral Students

Marlene Bagatto is an Audiologist at the National Centre for Audiology at the University of Western Ontario (UWO) in London, Ontario, Canada. She specializes in clinical research related to the Desired Sensation Level (DSL) Method for the prescription of hearing instruments. Dr. Bagatto has given numerous presentations and workshops related to the DSL Method as well as published several articles on the topic. In addition, Dr. Bagatto provides clinical services to infants involved in the Ontario Infant Hearing Program at the H.A. Leeper Speech and Hearing Clinic at UWO. She also serves as the Amplification Consultant and Instructor for the Ontario Ministry of Children and Youth Services' Infant Hearing Program. In 2007, Dr. Bagatto received the Young Innovators Award from the Government of Canada for her work on hearing aid fitting procedures for infants and young children.  Dr. Bagatto is currently a PhD Candidate in the Hearing Science Field, Health and Rehabilitation Sciences Program and is a Vanier Canada Graduate Scholar. Her doctoral research focuses on pediatric outcome measurement.

Jeff Crukley, MSc

Jeff Crukley is a PhD Candidate in the Hearing Science Field, Health and Rehabilitation Sciences program within the University of Western Ontario's Faculty of Health Sciences.  Jeff's MSc work in Audiology examined sound localization abilities of normal hearing adults and children. Jeff's doctoral work focuses on pediatric hearing aid fitting for non-quiet environments, and is funded by the Natural Sciences and Engineering Research Council.

Danielle Glista is a PhD Candidate in the Hearing Science Field, Health and Rehabilitation Sciences program within the University of Western Ontario's Faculty of Health Sciences.  Danielle's research interests relate to the impaired auditory system and efficacy of innovative hearing aid technology. She is currently studying how aided speech perception ability changes over time for listeners with high-frequency hearing loss. Her research is supported by the Canadian Institutes of Health Research and Phonak AG.

Sheila Moodie is a Research Audiologist at The National Centre for Audiology, London, ON, Canada. She has spent much of her career assisting with the development of the Desired Sensation Level (DSL) Method and its transfer to clinicians, hearing aid and real-ear system manufacturers. She has assisted with the development of clinical protocols related to the DSL Method, including the use of the real-ear-to-coupler difference (RECD) measurement for predicting hearing aid output for infants and young children. Sheila is currently a PhD Candidate in the Hearing Science Field, Health and Rehabilitation Sciences Program, studying topics related to knowledge translation and evidence-based practice and is funded in part by the Canadian Institutes of Health Research.
