I am a Postdoctoral Research Associate at the Aerospace Computational Design Lab (ACDL), where I work under the supervision of Professor Karen Willcox. My research program is focused on computational methods and numerical analysis for control, optimization, design and uncertainty quantification of large-scale dynamical systems. To enable—or speed-up—these computationally expensive tasks, I am interested in developing new methods and algorithms that use reduced-order surrogate models. With an increased availablilty of data available, I am interested in integrating information from data into decades-old, accurate, first-principles computational models.
