Los Angeles, CA, USACollaboration with Me. I am open to external opportunities for invited talks, research collaborations, and employment (only on the part-time/advising/visiting basis). Let us have a chat by email. I frequently visit major cities, e.g., Seattle, NYC, Chicago, Boston, Atlanta, and Bay Area to meet people, give talks, and host social events.
Research Interests: My research focuses on creating reliable, efficient, and accessible AI systems. These efforts span from building theoretical foundations to delivering practical tools and real-world impact:
