Biography

Shahram Yousefi is passionate for technology, innovation, teaching, learning, sustainability, harmony, and helping others. These passions are particularly fulfilled by teaching graduate and undergraduate courses in engineering, advising and supervising students, developing new ideas and technologies, developing curriculum, and organizing related workshops and conferences.

Shahram received his B.Sc. in electrical engineering from university of Tehran, Iran. Having worked in industry for a few years, he joined the department of electrical and computer engineering of university of Waterloo, Waterloo, Canada, as an M.A.Sc. student where he received his PhD. While still a Ph.D. student at Waterloo, he instructed undergraduate courses and received more than 20 research and teaching awards and scholarships including the NSERC PGSB, OGS, OGS-ST, and Sandford Fleming foundation teaching awards.

Since 2002, he has held positions at Edward S. Rogers Sr. department of electrical and computer engineering of university of Toronto, Toronto, Canada, Ecole Polytechnique Fédéral de Lausanne (EPFL), Switzerland, and department of electrical and computer engineering of Queen's university, Kingston, Canada, where he is currently a tenured full professor, a senator, and Acting Department Head.

At Queen's, he has served as a member of the curriculum committee, undergraduate chair, IEEE chair and vice chair, chair of sub-committee on nonacademic discipline (SONAD), and biennial symposium on communications (BSC) chair. He is a senior member of Institute of Electrical and Electronics Engineers (IEEE) and a Professional Engineer (P.Eng.) with PEO of Canada and currently serves as an editor for the IEEE Communications Surveys and Tutorials journal. Prof. Yousefi was appointed the Editor-in-Chief of the Canadian journal of electrical and computer engineering (CJECE) in Jan. 2013.

Opportunities

Call for Associate Editors, CJECE

The Canadian Journal of Electrical and Computer Engineering (CJECE) is the flagship IEEE technical journal of the area in Canada. The CJECE (ISSN-0840-8688), issued quarterly, has been publishing high-quality refereed scientific papers in all areas of electrical and computer engineering since 1976 and is indexed in ISI and IEEE Xplore. The journal has been restructured since 2010; the current acceptance rate of the journal is ~1.5% and the expected first decision turn-around time is around 2 months.

The papers we publish are typically 3-10 pages long (in final two-column form) and focus on original research in the field of electrical and computer engineering (ECE), current electrical and computer engineering practice, or the history of electrical and computer engineering relevant to the Canadian scene. We also consider brief descriptions of new technical achievements and application articles related to novel realizations or major system implementations. Tutorial, review, and survey articles are also welcomed. A number of special issues will also be announced in the next few months.

All submitted manuscripts are reviewed by independent referees as coordinated by the Associate Editors (AE). In my capacity as the journal's EiC, I extend an invitation to researchers in all areas of ECE to submit an application for an AE position.

Each AE is appointed on a 6-month probationary term to be extended to a 2-year term. AEs will receive a small number of papers each year in their general areas of expertise. Successful volunteer candidates will be required to secure a minimum of 3 independent reviews for each paper in 4 weeks.

Interested researchers are invited to send their intents along with an up-to-date CV via email to s.yousefi at the domain queensu.ca or on LinkedIn. The CV is not required if the LinkedIn account contains the relevant information and the track record in research and publications.

NOTE: We are currently looking for AEs in the areas of computers, software, communications, information theory, and signal processing.
