Bio
I'm André Gustavo Carlon, a postdoctoral researcher and stochastic-optimization enthusiast with a Ph.D. in structural engineering. My work sits at the intersection of statistical methodology and real-world applications: I develop and analyze novel stochastic-gradient techniques—variance reduction, optimal preconditioning—to tackle problems in optimal experimental design, reliability-based design optimization, and efficient training of machine-learning models. I also serve as an Associate Editor for Statistics and Computing.
