Claire McSweeny

B.A. Biology at Wilfrid Laurier University

Claire is a M.Sc. candidate at the Institute of Medical Science at the University of Toronto. She joined Archie’s Cochlear Implant Lab in 2017 after completing her Honours Bachelor of Arts in Biology at Wilfrid Laurier University in Waterloo.

Claire is studying the development of spatial awareness and navigation deficits in children with hearing loss and will be looking at how these deficits affect the vestibular, memory and cognitive abilities of children with bilateral cochlear implants and single sided deafness. In her free time Claire enjoys painting, working out and cooking.


Daniel Smieja

BEng, MHSc

Daniel graduated in 2018 with an MHSc from the Institute of Biomaterials and Biomedical Engineering (IBBME) at the University of Toronto. He joined the Cochlear Implant Lab in 2016 after completing his Bachelor’s degree in Electrical and Biomedical Engineering at McMaster University in Hamilton.

Daniel’s research looks at EEG source localization and functional connectivity children with cochlear implant users. Outside of the lab, he can be found on the squash court or playing the guitar.

Melissa Polonenko

H.B.M.Sc., M.Cl.Sc., Aud(C), Reg. CASLPO, FAAA, PhD Candidate

Melissa Polonenko is a PhD candidate in the Institute of Medical Sciences and Collaborative Program in Neuroscience at the University of Toronto, as well as the Neurosciences & Mental Health Program at SickKids. She joined the Cochlear Implant Lab in 2012 after working as an audiologist at the Glenrose Rehabilitation Hospital in Edmonton, Alberta. While working clinically, Melissa actively participated in clinical research on telehealth audiology, diagnostic measures in infants and children, as well as hearing aid outcomes in children as part of The Network of Pediatric Audiologists of Canada.

Melissa completed her Master’s of Clinical Science in Audiology at the National Centre for Audiology at The University of Western Ontario. Under supervision from Dr. Susan Scollie and Dr. Richard Seewald, she evaluated speech production of children with high frequency hearing loss who use nonlinear frequency compression hearing aids, and evaluated a hearing aid prescription algorithm for use in adults. Melissa also completed her Bachelor of Medical Sciences (Honours) from the University of Western Ontario in the Schulich School of Medicine & Dentistry. She completed her thesis on the regulation of gonadotropin releasing hormone type I receptor (GnRH-RI) activity during placentation in humans with Dr. Andy Babwah.

Melissa’s current research interests involve auditory development and binaural hearing in children with asymmetric hearing loss who use both a cochlear implant and a hearing aid (bimodal hearing) to hear. She is also evaluating the functional benefit of bimodal listening for music perception. She is also involved in clinical research within the Departments of Communication Disorders and Otolaryngology at SickKids and she volunteers on the Science and Education committee for the Canadian Academy of Audiology.

D. Ellen RickD. Ellen Rick

B.Sc., M.Cl.Sc., Reg. CASLPO

Ellen Rick was a M.Sc. candidate in the Institute of Medical Sciences and the Collaborative Program in Neuroscience at University of Toronto. Ellen’s academic career started with a Bachelor of Science with honours in Neuroscience at Carleton University focusing on the neural basis of sensory processes. She then went on to complete a Master of Clinical Science in Audiology at Western University, where she was actively involved in her department and student body. She completed her final placement in Winnipeg, MB where she worked with both adults and children with cochlear implants from all corners of the province of Manitoba. She is now a registered audiologist in the province of Ontario.

Ellen’s research project looks at coordinating the left and right cochlear implant for children with two cochlear implants to ensure balance in level and frequency between the two ears. She hopes to encourage the field of audiology in the direction of integrating neuroscience into clinical practice. Outside of school, Ellen is a long-distance runner, a horse-back rider, and a Canadian fiction enthusiast. She’s since moved on to pursue clinical experience as an audiologist.


Joshua GnanasegaramJoshua Gnanasegaram
Honours B.Sc, M.Sc. student

Joshua joined the Cochlear Implant Lab in September 2014 as an M.Sc. student in the Institute of Medical Science and Collaborative Program in Neuroscience (CPIN) at the University of Toronto, after completing his Honours Bachelor of Science in Neuroscience at the University of Toronto.

Joshua’s graduate research project looked at myogenic potentials that are thought to be the result of the spread of the cochlear implant’s electrical energy to the vestibular system. Using electrophysiological techniques in conjunction with visual perception tests, he aimed to clearly characterize these responses and examine the impact of this inadvertent and traditionally unwanted stimulation on children using cochlear implants. Joshua was also an active member of the Institute of Medical Science Student Association (IMSSA) Executive Council and he enjoys teaching the piano in his spare time.

Salima JiwaniSalima Jiwani
H.B.A., M.Sc., Reg. CASLPO, PhD

Salima Jiwani successfully defended her PhD in December 2014 at the Institute of Medical Sciences and collaborative program in Neuroscience at the University of Toronto.

She joined the Cochlear Implant Lab in 2010 after completing a clinical Master of Science in Clinical Audiology and a Master Thesis at the School of Human Communication Disorders at Dalhousie University, where she investigated the use of a paired-click stimulus paradigm in the auditory brainstem response test to detect Vestibular Schwannomas more reliably. Salima Jiwani also holds an Honours Bachelor of Arts in Linguistics and French from the University of Toronto.

Salima’s research explored the long-term development of the auditory system and the neural networks that are activated by auditory input in adolescents who are deaf and have used a cochlear implant to hear for most of their lives.

Michael is a M.Sc. candidate in the Institute of Medical Science at the University of Toronto.  He joined the Cochlear Implant Lab in 2011 after completing his B.Sc. in Human Biology at the University of Toronto in 2008.Michael’s current research focuses on the development of binaural processing in children who receive simultaneously implanted bilateral cochlear implants. He is particularly interested in how these children use binaural cues to localize sound and detect speech in noise. Using electrophysiological and neuroimaging techniques, he also examines how the cortical responses of these children change in response to changes in binaural sound cues.

Patrick was an M.Sc. candidate in the Institute of Medical Science at the University of Toronto. He first joined the Gordon lab in 2010 while completing his BM ScH in Physiology at the University of Western Ontario. Patrick’s graduate research project examined cortical responses of paediatric cochlear implant users. His focus dealt with the initial differences in the responses between unilaterally and simultaneously implanted children, and also how those responses developed over time.
