About

Welcome to my personal page. Currently, I work as a data scientist at Stitch Fix.

Previously, I obtained my PhD at Stanford working with Ramesh Johari. My interests are at the interface of statistics, mathematics and computer science and I aspire to bring theory and practice together. My research focuses on how human interaction with learning systems affects outcomes and how we can design such systems to take advantage of this.

Papers

Experience

  • Stitch Fix, Summer 2014 and Summer 2015

    Stitch Fix is reinventing the retail industry through innovative technology. During my two summers at Stitch Fix, I worked on improving the recommendation engine that is used by stylists, along with tinkering on some side projects. Furthermore, I wrote a blog post for the tech blog on multiple testing.

  • HP Labs, Summer 2013

    HP Labs is the research division of Hewlett-Packard. I worked under supervision of Rob Schreiber and with fellow intern Austin Benson on fault tolerance for the next generation of super computers. We demonstrated that we can make numerical methods resilient to silent errors at negligible cost by using mathematical properties of the methods. This has led to the publication of Silent error detection in numerical time-stepping syhemes.

Teaching

  • CME 193 Introduction to Scientific Python

    Instructor for a one-unit introductory course on Python multiple times. We cover the basics of Python, and dive deeper into the mathematically oriented libraries, such as Numpyy Scipy and Matplotlib. We also cover modern tools, such as the Jupyter Notebooks.

    Material of the course is available on the course website and github.

  • MS&E 226 Small data

    Teaching assistant for the excellent course on “small” data taught by Ramesh Johari.

  • CME 106 Introduction to Probability and Statistics for Engineers

    Teaching assistant for a first course in probability and statistics for engineering students at Stanford.

    A review of the probability theory taught in the class can be found here.

Side projects

  • I submitted a bot to the Halite artificial intelligence competition which finished in the top 3%.

  • Here is a collection of some Jupyter notebooks for fun little projects. For example, there is a notebook to help me fill out my March Madness bracket by modeling basketball outcomes using Stan.
