  <p class="eyebrow">About</p>
  <p>I'm a second year PhD student at Carnegie Mellon University studying <a
      href="https://www.cmu.edu/dietrich/statistics-datascience/index.html">statistics</a> and <a
      href="https://www.ml.cmu.edu/">machine learning</a>. This summer, I'm a research intern at <a
      href="https://www.abridge.com/">Abridge AI</a>; last summer, I was an applied science intern at <a
      href="https://aws.amazon.com/">Amazon Web Services</a>. Previously, I studied <a
      href="https://ww3.math.ucla.edu/">mathematics</a> at UCLA.</p>
  <p>If you would like to contact me, please use one of the links on this page. Alternatively, you can try <a

<section class="section">
  <p class="eyebrow">Research</p>
  <p>I'm extremely lucky to be advised by <a href="https://www.stat.cmu.edu/~aramdas/">Aaditya Ramdas</a> and
    <a href="https://nmboffi.github.io/">Nicholas Boffi</a> at CMU. Most recently, I've been interested
    in generative
    modeling, deep learning theory, and optimal transport.
  </p>
  <p>I am most fascinated by theoretical questions with immediate practical implications, such as:</p>
  <p class="section-question">Why do modern machine learning methods work so well?<br>Where do they fall short, and how
    can we design better ones?</p>
</section>

<section class="section">
  <p class="eyebrow">Beyond research</p>
  <p>In my spare time, I've been known to lift heavy things, watch TV
    shows, read books, and play board games with friends. I've recently enjoyed playing <em><a
        href="https://gloomhaven.fandom.com/wiki/Gloomhaven:_Jaws_of_the_Lion">Gloomhaven: Jaws of the Lion</a></em> and
    highly recommend the <em><a href="https://en.wikipedia.org/wiki/Mistborn">Mistborn</a></em> and <em><a
        href="https://en.wikipedia.org/wiki/The_Stormlight_Archive">The Stormlight Archive</a></em> series by Brandon
    Sanderson. I
    also play Indian classical music on the <a href="https://en.wikipedia.org/wiki/Bansuri">Bansuri flute</a>.
  </p>
  <p>
    In the past, I ran marathons, biked long distance, and hiked
    glacier mountains supporting <a href="https://ashanet.org/">Asha for Education</a> (please donate <a
      href="https://ashanet.org/donate/">here</a>!), and volunteered for the <a
      href="https://www.crisistextline.org/">Crisis Text Line</a> as a Crisis Counselor (donate <a
      href="https://www.crisistextline.org/donate/">here</a>!).
