First, I would like to highlight my work as a chemist analyst at the analytical chemistry department in Labstat Inc in Kitchener city for two years and a half. During this period, I have worked as a chemist analyst running a vast platform of Agilent Technologies GCMS units. Moreover, I have performed all calibration and verification operations as well as analysing data, running of samples, calculation of results, and the monitoring of controls used in the analytical process.Second, before immigrating to Canada, I have worked for eight years as a licensed senior engineer in the department of analysis at the biotechnology centre of Sfax in Tunisia, which is a genomic and analytic platform, functioning through the ministry of technology. Eventually, I became the chief executive of the analysis department in September 2017, adding responsibilities relating to seminars, operations, and management to my portfolio.
