Research Assistant
INRS
- Developed deep learning models with MATLAB to predict water temperature from meteorological data to support engineering at Beauharnois hydropower plant in Quebec.
- Conducted research on the development of a network for measuring and collecting water temperature data from covariates. We used mutual information and dimensionality reduction methods using MATLAB.
- Conducted web scraping of the Statistics Canada website to obtain meteorological data using Python.
Research Intern
TRIUMF
- Participated in a research internship at TRIUMF on the IRIS experiment with Dr. Rituparna Kanungo.
- Improved detector calibration with elastic scattering simulations in C++. The goal of the experiment was to demonstrate the particular halo structure of the lithium 11 isotope.
