Loïc Maréchal

Ph.D. in finance


I am a researcher at the Cyber-Defence Campus (armasuisse, Science and Technology) and HEC Lausanne. In this position, I apply private equity models to the cybersecurity sector to guide armasuisse's procurement decisions. I am also a lecturer in finance at the University of Geneva (LL.M.), ESSEC Business School (M.Sc.), and Les Roches (MBA). I have over 10 years of commodity markets experience, which includes working on trading desks and writing my Ph.D. dissertation. I have a strong interest in machine learning and market microstructure that I use for my own algorithmic trading (high-frequency/latency). I am a French citizen living in Lausanne, Switzerland.
