Jean-François Bégin

Thank you for visiting my home page. I am an Assistant Professor in the Department of Statistics and Actuarial Science at Simon Fraser University. I am also a fellow of the Society of Actuaries and of the Canadian Institute of Actuaries. My research interests include financial modelling, financial econometrics, filtering methods, high-frequency data, credit risk, option pricing, cyber risk, and pension economics. Before joining SFU, I completed my PhD at HEC Montréal under the supervision of Geneviève Gauthier.

Supervision

I am a committed and active supervisor at the graduate and undergraduate levels. I supervise students working on a range of topics that relate to actuarial science, financial mathematics, financial econometrics, statistics, and finance.

• Prospective Students
  

  I am recruiting exceptional actuarial and statistics students at all levels (undergraduate, Master's and doctoral students). I do not require trainees to come from a certain academic discipline, but I do look for a quantitative background. So, they could be actuaries, computer scientists, mathematicians, physicists, as long as they are comfortable with equations, models, and computers. Most importantly, they need to be capable of independent thinking, very curious, and have similar research interests to mine.

  If you are interested, please send me a complete CV and a copy of your transcripts by email. I will be in touch with you if your academic background fits my research program.
• Current Doctoral Students
• Golara Zafari: Golara's research focuses on pricing kernels and high-frequency econometrics.
• Louis Arsenault-Mahjoubi: Louis's research focuses on financial econometrics and Bayesian estimation of stochastic volatility models.
• Thomas Landry: Thomas's research focuses on pension economics and finance (co-supervision with M. Boudreault).
• Current Master's Students
• Alice Roberts: Alice's research focuses on high-frequency econometrics (co-supervision with P. Tupper).
• Nikhil Kapoor: Nikhil's research focuses on variable payment life annuities (co-supervision with B. Sanders).
• Vatsal Desai: Vatsal's research focuses on collective defined contribution schemes and smoothing mechanisms (co-supervision with B. Sanders).
• Yingfei Sun: Yingfei's research focuses on variable payment life annuities and volatility targeting (co-supervision with B. Sanders).
• Past Students
• Master's Students: Marie-Ève Malette, Lu Yi, Kanav Gupta, Fei (Michael) Mo, Cherie Ng, Louis Arsenault-Mahjoubi, Yige (Vivian) Jin, Xueyi (Wendy) Xu, Wenyuan Zhou.
