Punam Kumar Saha

Also known as Pranav Kumar Saha, Pranav Saha

Punam Kumar Saha is a biomedical imaging researcher whose work applies digital topology and deep learning to medical-image analysis. He earned computer science and engineering degrees at Jadavpur University, studied three-dimensional digital topology at the Indian Statistical Institute, and moved from research posts at Pennsylvania to Iowa. At Iowa, his work spans image analysis, topology, virtual bone biopsy and segmentation, including a 2020 deep-learning method for reconstructing trabecular-bone scans. He became an IAPR Fellow in 2016 and an AIMBE Fellow in 2017, received a 2021 Distinguished Investigator Award, and as of October 2026 is a professor of electrical and computer engineering and radiology at Iowa.

Timeline

  1. 1987–1989

    Degrees at Jadavpur

    He earns a BE in computer science and engineering at Jadavpur University in 1987, then an ME in the same field there in 1989.

  2. 1996

    A thesis on image topology

    The Indian Statistical Institute awards his doctoral thesis, “On Three Dimensional Digital Topology and Its Application to Image Processing,” in 1996. Dwijesh Dutta Majumdar supervises it in the Electronics and Communication Sciences Unit; it studies three-dimensional topology for image processing, computer vision, and medical imaging.

  3. 1997–2006

    From Pennsylvania to Iowa

    He joins the University of Pennsylvania as a postdoctoral fellow in 1997 and serves as a research assistant professor there from 2001 to 2006. He moves to the University of Iowa in 2006.

  4. 2016

    An IAPR fellowship

    He becomes an IAPR Fellow in 2016 for contributions to digital topology and geometry and their application.

  5. 2017

    An AIMBE fellowship

    He joins AIMBE’s College of Fellows in 2017 for work on morphometry, topology, shape, and scale, and algorithms for quantitative biomedical imaging.

  6. 2020

    A GAN-CIRCLE reconstruction method

    In 2020, he coauthors a deep-learning method called GAN-CIRCLE to reconstruct high-resolution trabecular-bone microstructures from low-resolution CT scans.

  7. 2021

    A Distinguished Investigator Award

    He receives the Distinguished Investigator Award from the U.S. Academy for Radiology and Biomedical Imaging Research in 2021.

  8. As of October 2026

    Professor at Iowa

    As of October 2026, he is a professor of electrical and computer engineering and radiology at the University of Iowa and a researcher with the Iowa Institute for Biomedical Imaging. His research includes tensor-scale image analysis, digital topology and geometry, virtual bone biopsy, image segmentation, and classification. He has served as an associate editor for international journals and on IEEE and AIMBE fellow-selection committees.

  1. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes University of Iowa. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  2. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes University of Iowa. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  3. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other universityIncludes University of Pennsylvania. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other university. We compare doctorate and 5+ year employment links, career timing and current workplaces for 187 major-prize and 1,111 best-paper winners.
  4. People shaping AI work at a median of 3 organizations over a career: 3 for university starters and institute and lab starters, versus 2 for company startersIncludes University of Pennsylvania. Across 6,853 people shaping AI with a dated work role, we estimate a median of 3 parent organizations over a career (mean 3.6), comparing role groups, starting sectors and starting decades from the 1950s to 2020–2026.
