    Day to day work

  • Developing theory towards the origin of stuttering and human speech/language production.
  • Analyzing speech data and results (linguistically, computationally and statistically).
  • Design and run experiments (developing software, interfacing hardware, and running subjects).
  • Design and create software packages for language testing (for educational and clinical usage)
  • Design, create and maintain my own web pages and bits on the speech group web pages.
  • Lab demonstration and supervision and marking of student projects.
  • PhD student supervision.

    Other current work includes the research of stuttering in Spanish speakers.

    WWW stuff:
    I have designed and created the questionnaire and am carrying out the survey of bilingualism and stuttering which is underway. An online transcription training course was also set up and maintained by me.

    Programming experience: (some of them are very limited)
    Machine code, Assembly, Basic, Pascal, Fortran77, Cobol, Prolog, C, C++, Java, Perl

    Programming environment:
    Unix, DOS, Windows

    Hardware environment:
    Cyber, PDP11, Sun, PCs

    Software (Windows) developed:
    I have designed and developed (system, linguistic material and programming) the ROST family of test for syntactic development in various languages (including English, Italian, Spanish, German, Cantonese, Danish, Bengali, Syhleti, Punjabi, Turkish, Russian). It supersedes the earlier version: Preschool Reception of Syntax Test (PROST): testing the syntactic development of 2-4 year olds
    Computerized version of TROG: testing the syntactic development of 4-11 year olds
