• Performed 6-month rotations in the following teams:
• Machine Learning Model Validation: Performed independent validations andbenchmarking of ML/AI models used within various lines of business.
• Global Strategy: Developed quantitative analytics tools in Python with an Excel interface to support a team of strategists on the trading floor, e.g., a backtesting system for systematic trading, a multi-factor.
• Financial Engineering Model Validation: Developed C++ benchmarks to validate models such as redeemable term deposits, mortgage commitments, commodity swaptions, volatility surface generators, mortgage-backed.
• Model Development: Developed stress testing models for financial variables (e.g., MBS OAS) to support programs such as CCAR, DFAST and OSFI-MST. Created an R package to consolidate the development and implementation of.

• Worked on projects that aim to develop dynamic hedging strategies for segregated funds taking basis risk into account.
• Worked on projects related to catastrophe (CAT) bonds; developed statistical models for forecasting the risks of CAT bond funds; and performed empirical tests of CAT bond pricing models.
• Implemented a large family of regime-switching GARCH-type models in Rcpp using C++ object-oriented programming techniques (MSGARCH R package on CRAN).
• Worked on a project to study the impact of parameter and model uncertainty on the forecast of risk measures.
• Derived general expressions for obtaining raw, absolute, and conditional moments for a standardized version of the class of skewed distributions proposed by Fernandez and Steel (1998).

• Worked on a nuclear magnetic resonance quantum processor:
• Learned parameter estimation methods to characterize dipolar coupled spin systems.
• Studied the different approaches to the analysis of nuclear magnetic resonance spectra.
• Learned the gradient ascent pulse engineering optimal control algorithm.
• Became an experimented user of computer clusters such as SHARCNET.
• Worked on protocols to characterize the noise affecting the implementation of quantum gates.

• Worked on an experiment to efficiently detect quantum discord:
• Performed the simulations.
• Wrote the tomography and discord calculation softwares.
• Participated to the experiments, and analyzed experimental data.

Worked on an optical setup in which a liquid mirror, controlled via LabVIEW, automatically minimized the optical aberrations introduced by a poor quality mirror.
