Julio Deride

I am currently working as an Assistant Professor at the Faculty of Engineering and Science at Universidad Adolfo Ibáñez (UAI).  Previously, I held an Assistant Professor position at Universidad Técnica Federico Santa María (USM) and a postdoctoral position at Sandia National Laboratories, Albuquerque.  I got my Ph.D. in Applied Mathematics from the University of California, Davis, in 2017.

My academic interests lie at the interface of Stochastic Programming and Variational Analysis. I have developed approximation techniques for solving Stochastic General Equilibrium problems and their numerical implementations. Additionally, I have collaborated with research groups on Renewable Energies, focusing on the mathematical modeling of probability distributions of forecast errors for solar and wind power generation. Finally, I am interested in studying Duality Theory for Stochastic Programming problems and its connection with approximation techniques.

"...Yo creo que desde muy pequeño mi desdicha y mi dicha al mismo tiempo fue el no aceptar las cosas como dadas. A mí no me bastaba con que me dijeran que eso era una mesa, o que la palabra ”madre” era la palabra ”madre” y ahí se acaba todo. Al contrario, en el objeto mesa y en la palabra madre empezaba para mí un itinerario misterioso que a veces llegaba a franquear y en el que a veces me estrellaba...."
