Ioannis Gkioulekas

Also known as Yannis Gkioulekas

Ioannis Gkioulekas is a computer vision and graphics researcher who designs computational imaging systems, from cameras that see around corners to differentiable and neural rendering methods. After studying electrical and computer engineering at the National Technical University of Athens, he earned a Harvard PhD in 2016 and joined Carnegie Mellon's Robotics Institute in 2017. His paper on Fermat paths for non-line-of-sight shape reconstruction won the CVPR 2019 best paper award, he received a Sloan Research Fellowship in 2020, and his Walkin' Robin paper won best paper at SIGGRAPH 2024. The Bodossaki Foundation named him a 2025 Distinguished Young Scientist in applied sciences for artificial intelligence. He is an associate professor with tenure in the Robotics Institute at Carnegie Mellon University, where his laboratory works on computational imaging.

Timeline

  1. 2004–2009

    Electrical engineering in Athens

    He begins studies at the School of Electrical and Computer Engineering of the National Technical University of Athens in 2004. He receives his degree in 2009 after a thesis on computational attention supervised by Petros Maragos.

  2. 2014–2016

    Master's and PhD at Harvard

    At Harvard's School of Engineering and Applied Sciences, he earns a master's degree in 2014 and a PhD in 2016 under Todd Zickler. His dissertation, A Framework for Inverse Scattering, tackles inferring a material's scattering parameters from images of it.

  3. 2017

    Joining Carnegie Mellon

    He joins Carnegie Mellon University in 2017 as an assistant professor in the Robotics Institute. His research there spans computational imaging, computer vision and computer graphics.

  4. 2019

    CVPR best paper on Fermat paths

    With Shumian Xin, Sotiris Nousias, Kiriakos Kutulakos, Aswin Sankaranarayanan and Srinivasa Narasimhan, he wins the CVPR 2019 best paper award, chosen from about 5,000 submitted papers, for A Theory of Fermat Paths for Non-Line-of-Sight Shape Reconstruction. The paper presents an algorithm called Fermat Flow, which estimates the shape of an object hidden around a corner.

  5. 2020

    A Sloan Research Fellowship

    In 2020, he is one of 126 early career researchers to receive a Sloan Research Fellowship, as an assistant professor in the Robotics Institute. His recent focus is non-line-of-sight imaging, which reconstructs images from scattered light to reveal objects around corners.

  6. 2024

    Awards at SIGGRAPH and CVPR

    In 2024, Walkin' Robin: Walk on Stars with Robin Boundary Conditions, written with Bailey Miller, Rohan Sawhney and Keenan Crane, wins a SIGGRAPH best paper award. The paper introduces a grid-free Monte Carlo method for boundary value problems that needs no volumetric meshing or global solves. His CVPR 2024 paper Objects as volumes, with Miller, Hanyu Chen and Alice Lai, earns a best student paper honorable mention.

  7. 2025

    Bodossaki Distinguished Young Scientist

    The Bodossaki Foundation names him a 2025 Distinguished Young Scientist in applied sciences and technologies for artificial intelligence.

  8. As of October 2026

    Associate professor at CMU

    He is an associate professor with tenure in the Robotics Institute at Carnegie Mellon University, where his lab, Computational Imaging at CMU, designs optics, electronics and computation together into new imaging systems. Its research covers non-line-of-sight imaging, single-photon imaging, differentiable rendering and neural rendering.
