Ph.D. Student

Arizona State University

I am a 3rd-year Ph.D. student in Computer Science at Arizona State University, advised by Prof. Pooyan Fazli. Before that, I got my master's degree from the University of Southern California.

My research interests mainly lie in computer vision, especially in:

* Multimodal Large Language Models: MLLMs in video understanding; Hallucination detection in MLLMs; Enhancing video accessibility through MLLMs.
* Post-Training Alignment & Robustness: Post-training methods for improving vision–language model reliability, including temporal consistency modeling in video understanding, robustness against distorted or adversarial visual inputs, and alignment techniques for safety-critical video reasoning.
* Efficient Multimodal Learning: Token- and frame-efficient training for video and multimodal models, including adaptive token pruning, dynamic keyframe selection, and compute-aware model design that maintains accuracy with significantly reduced visual or textual input.
