Hello! I am an undergraduate student at Carnegie Mellon University studying Computer Science, with an intended additional major in Mathematics. My work focuses on Computer Vision, specializing in neuro-inspired AI algorithms and robust visual perception. I am currently exploring agentic video understanding and domain generalization.

-
We propose a cinematic video specification based on 200+ visual primitives to bridge the gap between AI generation and professional content creation.
-
We show that the Critique-based Human-AI (CHAI) oversight framework allows an 8B model to outperform GPT-5 and Gemini-3.1-Pro in video reasoning.
-
We demonstrate that training on CHAI triplets enables professional-grade generation of complex cinematic techniques like dolly zooms and rack focus.

-
We propose structure-first learning, a pretraining paradigm that uses line drawings to induce more compact and generalizable visual representations.
-
We show that training on line drawings develops stronger shape bias, significantly improving data efficiency for tasks.
-
We demonstrate that structural pretraining produces compressible representations that lead to better distillation and higher performance in lightweight student models.

3-D Image Based Deep Learning for Dementia Diagnosis
George Liu, Guillermo Goldsztein
-
We propose a 3-D convolutional architecture that processes full MRI volumes to capture complex structural patterns missed by traditional 2-D analysis.
-
We show that training on T1-weighted MRI scans from the OASIS-3 dataset enables the effective identification of brain atrophy for automated diagnosis.
-
We demonstrate that maintaining spatial dimensionality through 3-D convolution significantly improves diagnostic reliability compared to slice-based classification methods.
