Alexander Strang

I am an assistant teaching professor in Statistics and Data Science. I joined Berkeley in 2023 from the University of Chicago. I earned a PhD in applied math from Case Western Reserve University in 2020. Since then I have taught Calc I, II and III, Linear Algebra, Numerical Linear Algebra, Ordinary Differential Equations, Nonlinear Dynamics, Reinforcement Learning in Games, Probability (Stat 20, Data 140 and Stat 134), Pedagogy for Data Science (Data 375), Information Theory (Stat 157), Bayesian Statistics (Stat 238), and Data 102 (a topics course in statistics and decision making).

Outside of academia I’ve worked as a private research consultant and as a high-school track coach. I enjoy the outdoors, most conditioning/adventure sports (running, biking, swimming, hiking, skiing), and most acoustic music (classical, jazz, folk), and rooting for the Buffalo Bills.

I am excited to be teaching you all this semester! Probability is a subject worth appreciating for its beauty and its utility. I hope that you each find something to appreciate in it this fall.
