Acquired Brain Injury
I specialize in the study of paediatric communication and its disorders. My research program aims to understand the neurobiology of communication and to develop and evaluate new treatments for childhood brain-based speech and language disorders. To accomplish our aims, we use tools such as magnetic resonance imaging (MRI), electroencephalography (EEG), functional near infrared spectroscopy (fNRIS), transcranial electrical stimulation (tES) and transcranial magnetic stimulation (TMS). I partner with health care practitioners, researchers, clients and their families for the purpose of accelerating our understanding of the best rehabilitation practices for the developing brain. Please see the CONNECT Lab research page for current and upcoming projects.
Prospective postdoctoral fellows, PhD, and MSc trainees hoping to train with Dr. Beal should familiarize themselves with current CONNECT Lab projects and his published works (click on Publications) as well as the training program at the University of Toronto. Note that there are two application deadlines for doctoral and masters programs: February 1 and June 1.
Interested trainees may send an email to Dr. Beal that includes their curriculum vitae, unofficial transcripts and their reasons for wanting to train in the CONNECT Lab. Undergraduate trainees hoping to join the CONNECT Lab are encouraged to apply for a paid summer internship with Dr. Beal via the Ward Family Summer Student Research Program.
Volunteer trainee opportunities are limited. However, if you are passionate about the neurobiology of language, cognitive neuroscience, neuromodulation and neurorehabilitation we would love to hear from you. Previous research experience and proficiency in computer programming languages such as Python, Matlab and R are an asset but not a requirement.
