Work

I am an Assistant Professor in the Department of Electrical and Computer Engineering at Northeastern University. I direct the Spatial Intelligence Research Group (SINRG). I am interested in advancing research in spatial intelligence, which spans several interconnected areas of computing and human-centered technologies:

  • Immersive Multimedia Foundations

    Representation, compression, and streaming of dynamic spatial media including 4D point clouds, meshes, volumetric video, world models, and digital twins for real-time immersive experiences.

  • Internet and Wearable Systems

    Networked systems and communication for smart glasses and immersive applications, and distributed infrastructure that supports spatial computing at scale.

  • HCI, Visualization, and Graphics

    Interfaces and visual systems that enable humans to interact with spatial data through AR/VR platforms, collaborative environments, and interactive visual representations of complex environments.

  • Education, Learning, and Workforce Training

    Using immersive technologies to transform education, training, and skill development through experiential learning systems and collaborative digital environments.

My work has been supported by the U.S. National Science Foundation (NSF), the National Security Agency (NSA), and the U.S. Department of Defense (DoD). It has received the Best Reproducible Paper Award at ACM Multimedia Systems (MMSys) 2025, the Best Demo Award at ACM HotMobile 2025, the 2025 Innovation Award from the AI-RAN Alliance, the Best Demo Award at DARPA SRC Symposium 2023, and the Best Paper Award at IEEE Symposium on Multimedia 2021.
