My friends Jan Boman, Fulton Gonzalez, Alemdar Hasanov, and I at the minisymposium Modern Challenges in Imaging, Tomography, and Radon Transform celebrating my birthday at the Inverse Problems Modeling and Simulation Conference, May 22-28, 2022.

Here is an article about my research and mathematical life over the last 45 years in the Journal of Inverse and Ill-Posed Problems.

Tufts has an NSF summer research program Visiting and Early Research Scholars’ Experience in Math (VERSEIM-REU). Our program is aimed at students early in their college careers, and we are committed to enhancing the educational experiences of first-generation or underrepresented undergraduate students. Please check out the website and this article about the 2021 VERSEIM scholars.

  • A new SIAM book Computed Tomography: Algorithms, Insight and Just Enough Theory, editors Per Christian Hansen, Jakob Sauer Jørgensen, and William R. B. Lionheart includes a chapter by TQ on limited data tomography. Here is a SIAM News article on the book, and here is my chapter (with permission of SIAM).
  • Here is a talk I gave about work with Peer Kunstmann and Andreas Rieder on seismic imaging at the International Zoom inverse Problems Symposium at U.C. Irvine
  • Here is the video for a talk in Vienna in 2021 on work with colleagues, James Webber and Eric Miller of the Tufts ECE department.
  • Here are the slides for a purer talk and here are slides a more applied talk on our analysis of artifacts in limited data X-ray CT with Leise Borg, Jurgen Frikel, Jakob Jorgensen. Both were given at the SIAM Imaging Sciences Meeting, June 2018, Bologna. Here is a preprint of the article.
  • Here is a talk I gave at BIRS in 2015 about the paradigm Jurgen Frikel and I developed to understand visible singularities and added artifacts in limited data tomography, including PAT and Sonar [SIAM J. Appl. Math., 75(2),(2015) 703–725. (23 pages)]
  • If you would like to learn about microlocal analysis and imaging, check out Microlocal Analysis in Tomography, with Venkateswaran Krishnan, a chapter in Handbook of Mathematical Methods in Imaging, 2e, Editor Otmar Scherzer, Springer Verlag, New York, 2015. The book is at:
  • Special issue of Sensing and Imaging, Recent Developments in Sensing and Imaging
  • Special issue of Inverse Problems, Generalized Radon Transforms and Applications in Tomography
  • Special issue of Inverse Problems, Modern Challenges in Imaging Guest editors: B. N. Hahn, E. T. Quinto, and G. Rigaud, 26 articles accepted.
    This issue was motivated by the conference of the same name at Tufts honoring Tufts’ only Nobel Prize winner, Allan Cormack, a pioneer in tomography.
