About Me.

I am the Aravind K. Joshi Assistant Professor in the Department of Computer and Information Science at the University of Pennsylvania, where I lead the Penn Computer Graphics Lab and I am also a member of the General Robotics, Automation, Sensing & Perception (GRASP) Lab.

Previously, I was a Lise Meitner Postdoctoral Research Fellow at Max Planck Institute for Informatics. I received my Ph.D. degree at the University of Hong Kong in 2019.

My research interests are at the interface of Computer Graphics, Computer Vision, and AI, with a focus on Neural Scene Representations, Neural Rendering, Human Performance Modeling and Capture, and 3D Reconstruction. I am especially excited about exploring a new genre of 3D reconstruction and rendering algorithms for human characters and general scenes, which combine classical computer graphics pipelines with deep learning techniques.

My long-term vision is to develop AI technologies that can perceive, understand and interact with 3D objects, people, and environments. Specifically, my research will pursue three goals:

(1) High-quality 3D reconstruction of real-world scenes from sparse inputs;

(2) Efficient and photo-realistic image synthesis of real-world scenes with 3D control;

(3) Large-scale 3D scene generation.

Prospective Students.

There are multiple open research positions in my Lab. Currently, we are actively looking for summer interns and visiting students.

Topics of interest include:

  1. Neural Representations and Rendering for 3D/4D Reconstruction
  2. 3D/4D Generative Models
  3. Physics-aware 3D/4D Reconstruction and Generation; Physics Simulation
  4. Physics-based Human Motion Generation
  5. LLM guided Graphics and Vision
  6. Neural Representations for Robotics
  7. Other topics in Graphics and Vision

If you are interested in visiting or applying for a research position (e.g., intern, PhD, visiting PhD, or postdoc) in the lab, please fill in the form. We review the form submissions on a weekly basis. You will be contacted if a fit can be found. Due to the high volume of emails regarding applications, please refrain from emailing me directly. Thank you!
