About Joining My Group

Long story short, I am always looking for motivated and talented students. I also receive hundreds of emails a day and cannot respond to all inquiries about joining my group. This document is not meant to be unfriendly, but just to save both of us time (many of these things are things I'd say in an email back).

• If you are a NYU student: I may be taking students in Fall 2023, but will not have information until later in the summer
• If you are a UM student: I am not taking new students at UM.
• If you are a neither: at the moment, I am not looking for postdocs, visitors, or new collaborators.

If you've read this page and think you have a question that has not been answered, please feel free to email and put ``(JJ Gibson)'' in the subject line. I will always do my best to answer these.

Executive Summary

Research: I work on learning-based computer vision. I want to develop autonomous systems that can learn to build representations of the underlying state and dynamics of the world through observation. I am particularly interested in the following three areas:

• Understanding 3D from pictorial cues. One of my goals for the past ten years has been enabling computers to perceive the 3D world with the same ease that humans do. I'm broadly interested in this area, and as our ability to extract 3D from images has gotten better, I've become increasingly interested in how to optimally use this information in the context of multiple views.
  
  Representative projects: (1) Sparse View Planar Reconstruction investigates a wide-baseline problem that falls in between areas that computer vision knows how to do well; (2) Direct Ray Distance Functions shows how to produce full-3D reconstructions while learning on realistic non-watertight 3D data.
  
  
• Understanding the Interactive World. While images are themselves static, they depict a world of possibility in which we can move about and manipulate the world. I would like to give computers the ability to perceive this world and have focused on understanding interactions as they occur, from the perspective of hands and 3D.
  
  Representative projects: (1) 100 Days of Hands, a system that aims to provide basic information about hands that just works on fairly unconstrained data. Our system has been adopted by EPIC-KITCHENS; (2) Understanding Articulation in Videos shows how to extract a quantitative understanding of interacting 3D from ordinary videos for a common class of objects.
  
  
• Measurement systems for basic sciences, especially solar physics. I have collaboratated with experts in other fields to build ML-based systems for measurements for basic science. One focus has been virtual instruments for solar physics that enhance the value of space missions. Developing and verifying systems that collaborators like requires long-term investment, and is intensely satisfying.
  
  Representative projects: (1) SynthIA, a best-of-both worlds learning-based magnetogram system currently being integrated into the SDO pipeline for distribution as a data product; (2) Skelevision, a deep learning approach to measuring museum skeletal specimens, which we hope will let us ask questions about the relationship between temperature and bird morphology at unprecedented scales.
  
  

Teaching and mentoring: I've been able to work on these projects via collaboration with a wonderful group of student collaborators, ranging from the PhD to the BS level. In addition to current students, I'm proud of a large number of MS and BS students now off doing a wide variety of great things in both industry and academia. As a classroom instructor, I've been able to share computer vision with over 1,000 students over the past few years, including over 925 undergraduate students.

Service and outreach: In addition to internal service and one-off outreach efforts, I have run UM's AI4All Summer Program since 2019, which has taught 100 high schoolers over the past four years. I also regularly serve the vision community as an area chair for conferences (CVPR 2019 — 2022, NeurIPS 2020 — 2022, ICLR 2021, ECCV 2022, among other) and as an action editor for TMLR.

I've also provided my expertise for the public interest, for example doing pro-bono work for the Michigan Innocence Clinic. My findings helped exonerate a man who was wrongfully convicted of first degree murder and who was serving a sentence of life without parole.

Funding: These endeavours have been generously supported by both public and private funding, including a NSF CAREER Award (2022). My group's work has been sponsored by The National Science Foundation, DARPA, Toyota Research Institute, The Procter & Gamble Company, Nokia Networks, NASA, and the Lockheed Martin Solar and Astrophysics Laboratory as well as the University of Michigan's Precision Health Initiative and the Michigan Institute for Data Science.

Sometimes when I feel a creative itch, the end result is a joke publication (which despite the name often have a serious point to make). These are all done with the one and only Daniel Maturana.
