<h2>Biography</h2>
<p>
I am a Ph.D. student in the Computer Science Department at Virginia Tech, advised by Prof. Dan Williams. My research focuses on operating systems, with an emphasis on extended Berkeley Packet Filter (eBPF) and verification techniques. Currently, I am working on generalizing the eBPF verifier to enhance the reliability and correctness of operating system components.
