OBJECTIVE

Strong background in research in theoretical physics, well equipped with analytical and problem-solving skills as well as computational skills. Expanded my skills in Data wrangling, and exploration, descriptive and inferential statistics, querying, visualization and analytics tools. Team worker, love challenges, positive attitude. 12 years of post-secondary education which involves multiple analyses of experimental data which entailed extracting the useful and filtering out the irrelevant data.
