Daniel Valois is Full Professor at the Département de linguistique et de traduction at Université de Montréal where he teaches and conducts research in theoretical syntax, language acquisition and psycholinguistics. He received a PhD in linguistics from UCLA in 1991. His early work aimed at assimilating the structure of noun phrases to that of clauses, especially with respect to adjective/adverb placement and argument structure. Publications on this topic appeared in many refereed journals, including Linguistic Inquiry and the Canadian Journal of Linguistics, as well in Blackwell’s Syntax Companion and other major collective publications. His work has been presented at major conferences such as the North Eastern Language Society (NELS), the West Coast Conference on Formal Linguistics (WCCFL), the Generative Linguists of the Old World (GLOW) conference, the Linguistic Symposium on Romance Linguistics (LSRL), Going Romance, and Neurobiology of Language. He has since developed interests in first language acquisition research as well as in the neurological bases of language (and, more currently, of music and language). Papers on language acquisition appeared in Probus, Language Acquisition, the Journal of French Language Studies and the proceedings of the Boston Conference on Child Language Development, among others. He has been a member of the editorial board of Probus, a prominent journal of Romance languages, since 1996.
Current projects include ERP analyses of argument structure, nominal agreement and conceptual semantics, the effect of music training on the syntactic competence of language-impaired patients, and the neurological aspects of morphological derivation processing.

Dehbozorgi, Mahya (M.Sc. Candidate)
Kassab, Amal (M.Sc. Candidate)
2023   +

A former architect from Aleppo, Syria; my career took a new turn upon arrival to Montreal by enrolling in mechanical engineering studies in order to integrate previous design experience into the construction of animated structures. Deeply interested in improving the modern lifestyle and addressing several of today’s issues, such as energy, sustainability and human health, I approached the topic of wind energy in urban areas in several earlier projects; an experience that resulted in a project proposal to Dr. Parschivoiu at Concordia University for a special turbine design in order to improve the yield of wind turbines at low speeds. By enrolling in the bioengineering program with Dr. Sawan, I will be fulfilling my goal of tackling human health issues using modern day technology, the inspiring work that Dr. Sawan’s group have achieved so far is the perfect environment for approaching the topic of micro energy harnessing in order to create autonomous implants and devices while working on the mechanical engineering aspect of various other bioengineering topics, such as the NIRS/EEG helmet design.
