Hi! I'm Ziqian Zhong. I'm currently a <span id="phd-year"></span>PhD
student at Carnegie Mellon University, advised by
<a href="https://www.cs.cmu.edu/~aditirag/">Aditi Raghunathan</a>.
</p>
<p class="bio">
Previously, I studied computer science and math at MIT, where I
worked with <a href="https://www.mit.edu/~jda/">Jacob Andreas</a>
and <a href="https://physics.mit.edu/faculty/max-tegmark/">Max Tegmark</a>.
I also worked as a research scientist at
<a href="https://pika.art/">Pika</a>, where I led the development of Pika 2.0.

<strong>AI Safety and Interpretability.</strong> My research seeks
principled approaches to improve the robustness, controllability,
and alignment of large language models with human values.

<p>
I'm always excited to collaborate with researchers at CMU and
beyond. If you're working on related problems or have ideas
you'd like to explore together, please feel free to reach out!
