Naga Venkata Sai Raviteja Chappa

As a Research Post-Doctoral Fellow in Computational Approaches and Machine Learning at the Center for Autism Research in the Children’s Hospital of Philadelphia, I work under the mentorship of Dr. Birkan Tunç, developing innovative computational approaches for autism research. I completed my Ph.D. in Computer Engineering from the University of Arkansas (January 2021 - February 2025), where my dissertation “Vision-Based Multimodal Approaches in Human Behavior Analysis: Bridging Group Activity Recognition and Healthcare Monitoring” was conducted under Prof. Khoa Luu in the Computer Vision and Image Understanding Lab.

My research expertise encompasses human behavior analysis with multimodal data, visual temporal modeling, vision-language models (VLMs), and foundational models. My work spans applications including group activity recognition, healthcare monitoring, and responsible AI for content moderation. I previously earned an M.S. in Computer Engineering from Purdue University (2020) and a B.Tech in ECE from JNTU-K (2018).

With publications in venues like WACV, CVPR Workshops, and journals including Sensors and IEEE Access, I continue to advance the field by integrating advanced computer vision and deep learning techniques to address real-world challenges in healthcare and beyond.
