About
I am a Ph.D. candidate in Computer Science at UIUC,
advised by Ismini Lourentzou. I began my
doctoral studies at Virginia Tech, where I also worked under
Kurt Luther.
My research centers on reasoning in 3D and embodied settings, grounded
in a broader foundation of natural language processing and multimodal
learning. I study how structured representations — linguistic, spatial, and
geometric — can be integrated to let machines reason about the world in a grounded,
interpretable, and generative way.
Collaborative Reasoning Frameworks that unify language and 3D generation
Part-Level 3D Generation and articulation for structured objects
Embodied Uncertainty Embodied Agents that adapt reasoning and planning in dynamic environments
Across these directions I aim to build language-enabled systems
that do not merely predict tokens or pixels, but reason over
structure, parts, space, and action — drawing on theoretical
linguistics, 3D representation learning, and multimodal world modeling.
Beyond academia I co-founded Eternl.AI,
where I architect AI infrastructure for embodied intelligence in interactive gaming —
spanning agentic AI, long-horizon personalization, and
3D-world generation. We raised $400K at a $40M valuation.
