2. 1996–2003

   Research associate in image coding

   He joins the Faculty of Science and Technology at Tokyo University of Science as a research associate in 1996 and works on image coding and processing. From 2000 to 2001, he is principal investigator of a Grant-in-Aid for Encouragement of Young Scientists project on lossless compression of image data with predictors that minimize the coding rate. His lab offers Lossless Image Coding Using Minimum-Rate Predictors as open source.

3. 2003–2011

   Lecturer, then associate professor

   In 2003, he becomes a lecturer in the Faculty of Science and Technology. He and Susumu Itoh receive the Fujio Frontier Award of the Institute of Image Information and Television Engineers in 2006 for research and development of ultra-high-efficiency lossless coding of digital images. He becomes an associate professor in the Department of Electrical Engineering in April 2008, and in 2011 he coauthors the paper "Lossless Image Coding by Cellular Neural Networks with Minimum Coding Rate Learning".

4. 2014–2019

   Professor and probability modeling

   He becomes a professor in the Department of Electrical Engineering at Tokyo University of Science in April 2014. From 2017 to 2019, he is principal investigator of the Grant-in-Aid project Learning Based Probability Modeling for Efficient Image Coding. In 2018, he publishes "A Lossless Image Coding Method Based on Probability Model Optimization" at EUSIPCO with Tomokazu Ishikawa, Yusuke Kameda and Susumu Itoh.

5. 2018–2021

   PCSJ/IMPS chair and a paper award

   From November 2018 to November 2021, he is General Chair of PCSJ/IMPS, a pair of image coding and media processing symposia run by the Institute of Electronics, Information and Communication Engineers. In 2021, the Institute of Image Information and Television Engineers gives its Niwa-Takayanagi Paper Award to a paper he coauthors on lossless color image coding with probability model optimization, example search and adaptive prediction.

6. 2021–2022

   CNN-based lossless image coding

   The IWAIT Best Paper Award of 2021 goes to "Probability Model Adjustment for the CNN-based Lossless Image Coding Method", written by Hiroki Kojima, Yusuke Kameda, Yasuyo Kita, Ichiro Matsuda and Susumu Itoh. In 2022, he coauthors "Enhancement of CNN-based Probability Modeling by Locally Trained Adaptive Prediction for Efficient Lossless Image Coding" at the Picture Coding Symposium.

7. 2024

   Named an IEICE Fellow

   In 2024, he is named a Fellow of the Institute of Electronics, Information and Communication Engineers for research and development of lossless image compression algorithms. His paper with Haruka Sugiyama and Kaiyu Suzuki on lossless image compression using bits-back coding with a latent variable model wins the IWAIT 2024 Best Paper Award.

8. Since April 2026

   Professor of information science and technology

   He moves to the Department of Information Science and Technology in the Faculty of Information Science and Technology at Tokyo University of Science as a professor in April 2026.
