<p>
Hi! I'm a PhD student in <a href="https://www.cs.cornell.edu/" class="para">Computer Science</a> at <a href="https://www.cornell.edu/" class="para">Cornell University</a>, advised by <a href="https://www.racheesingh.com/" class="para">Prof. Rachee Singh</a>. My research interests revolve around systems, networking, and machine learning. I'm currently working on networking infrastructure for large-scale machine learning systems.
</p>
<p>
I received my B.S.E in <a href="https://cse.engin.umich.edu/" class="para">Computer Science</a> from the <a href="https://umich.edu/" class="para">University of Michigan</a> with Summa Cum Laude, and B.S.E in <a href="https://www.ji.sjtu.edu.cn/academics/undergraduate-program/degrees-programs/electrical-and-computer-engineering/" class="para">Electrical and Computer Engineering</a> from <a href="https://en.sjtu.edu.cn/" class="para">Shanghai Jiao Tong University</a> with honors. I had the fortune to work with <a href="https://www.mosharaf.com/" class="para">Prof. Mosharaf Chowdhury</a> at Michigan.
