Research Areas
  • Software Requirements Engineering
  • User Interface Design and Evaluation
  • e-Health
  • ICT for development and modeling to support Patient Education
  • PhD in Computer Science from Indian Institute of Technology, Kanpur, India in 1971
  • M.Tech in Electrical Engineering from IIT, Kanpur in 1968
  • B.E.(Hons) in Electronic and Communication Engineering from Guindy Engineering College, Madras in 1966.
Employment History
  • 2010 – Professor in the Dept of Computer Science and Software Engineering (CSE), Concordia University
  • 2006 –2010 Chairman of General Studies Unit (then renamed as Center for Engineering and Society) – Contributed to its growth and shaping.
  • 2004 – 2006 Professor in the CSE Department
  • 2001-2004 Chairman of the Computer Science Department – Contributed to hiring about 15 new faculty members, re-naming the department to include Software Engineering and have worked for the first CEAB accreditation.
  •  1974 -2001 Joined Concordia University as a PDF, and progressed in the career to a full professor in 1991 and continued. Went to the National University of Mexico as a visiting fellow during 1978.
  • 1968 – 1974 Served as Lecturer at IIT, Kanpur; planned and helped to establish the Graduate program in Computer Science at IIT, Madras in India
Teaching and Thesis Supervision
  • In the last 35 years of my service, I have taught a large variety of courses at all levels; contributed to the development and design of curricula several times. Of late my teaching commitments are reduced to one or two courses per year due to personal constraints. I teach (a) An undergraduate course on Computer Organization; (b) User Interface Design; at the graduate level(c) Software Engineering Case Study; or (d) Intelligent User Interfaces.
  • I have supervised a large number of students for their Bachelors level projects, and over 80 students at the Masters and PhD level. My specialty is in not only supervising my students for research training but also in mentoring them. Many of them graduated 25 years ago are still in constant contact with me. A gratifying experience.  
  • My research focus has been more on applied side than on pure theoretical side. As a result the research has been funded by several industries in the past. Currently I hold an NSERC Discovery grant and one industry supported grant.
  • The applied nature of research we conduct has resulted in 3 Canadian, US, and UK patterns owned along with my students.

Text Books Published


  • In the areas of Computer Logic and organization, Computer Architecture and Assembly Language Programming, along with my PhD thesis supervisor and Guru Dr.V.Rajaraman, Dr. Radhakrishnan has written three text books. Two of them are revised and re-printed several times since 1976. They are still used by more students in India.
