I am a PhD student at the Max Planck Institute for Security and Privacy (MPI-SP), advised by Meeyoung Cha. I received my MS in Computer Science and BS in Electrical Engineering from the Korea Advanced Institute of Science and Technology (KAIST). I am currently interning remotely for the United Nations Department of Economic and Social Affairs (UN DESA). Previously, I interned at the Institute for Basic Science (IBS) and Daewoong Pharmaceutical in South Korea.
Research Interests
My research focuses on applied AI and computational social science for societal impact. I am interested in building data-driven, scalable, and human-centered AI systems to understand human and machine behavior and support decision-making in real-world settings, with applications across security and privacy in the generative AI era, well-being, and public health. I approach this through two aspects: (1) studying the characteristics, behaviors, and emergent (mis)alignments in human-agent and agent-agent interactions, and (2) building powerful and explainable representations to analyze the characteristics of individual physical and mental health. Previously, I also worked on generative AI methods for antigen-conditioned antibody design.

I was a chemistry enthusiast, but everything changed when the Fire Nation attacked.
I am an ISTP, a mala and mint chocolate enthusiast, and I love my sugar gliders.
My hobbies are traveling 🏰, photography 📸, cooking 🥘, singing 🎤, visiting art museums 🏛️, and binge-watching 🍿
As a Chinese Indonesian, I also go by Zhixiong Huang (黃智雄), but 我不會中文 🥲
