詹妮     About

I am a postdoc at Princeton University, advised by Ryan Adams, working on artificial intelligence for design and simulation of dynamic processes and materials. I completed my PhD at Carnegie Mellon University, advised by John Kitchin, with dissertation titled "Machine learning models and uncertainty for atomic simulations". My published research includes fast, accurate models to approximate quantum chemical methods, investigation of transport phenomena and dynamics of liquid alloys, uncertainty quantification for machine learning and physical properties, and graphical and probabilistic methods for finance and macroeconomics.

While at CMU, I also received an MS in machine learning and interned at JPMorgan Chase, working on strategy at the Treasury and Chief Investment Office. Previously, I worked as a chemical engineer and graduated magna cum laude with a BS in chemical engineering from the University of Texas at Austin.

    Project summarized statistical guarantees of matrix completion problem, following matrix incoherence property (Candes and Recht 2009) and spikiness and rank measures (Negahban and Wainwright 2012). We additionally summarized the extension of the latter to a graph regularized matrix completion, as shown by Rao et al. 2015.
