Welcome to Sasaki's Laboratory

Our laboratory's main research fields are estuarine and coastal environmental studies based on coastal engineering, environmental hydraulics, and marine biogeochemical processes. We also cover sustainability science in coastal areas in developing countries. We aim to publish our research results in international journals.
Briefing for admission was held from 13:00 on April 27 (Sat), 2024.

  Research Introduction Video by SPRING GX Student Xinlei Shao2025-03-13
  The "Fostering Advanced Human Resources to Lead Green Transformation (GX)" project proposed by Professor Shin-ichi Ohkoshi (Project officer) has been accepted as a program for Support for Pioneering Research Initiated by Next Generation (SPRING) of Japan Science and Technology Agency (JST) since Autumn 2021. Hereinafter this project is referred to as "SPRING GX". Currently, 1154 doctoral students from across all schools of the University of Tokyo participate in this project. Xinlei Shao, a third-year doctoral student from our laboratory, is a current participant in this program. Her research focuses on developing a novel method for monitoring coral reef conditions by integrating underwater imaging hardware with computer vision models. Videos introducing […]

  Lab snowboard/ski trip in January 20252025-01-30
  The lab ski/snowboard trip came to Kagura for the first time in two years. It's convenient, being about 20 minutes by bus from Echigo-Yuzawa Station. We enjoyed an early dinner and hot spring at Michi-no-Eki Mitsumata.

  Deep learning for multilabel classification of coral reef conditions in the Indo-Pacific using underwater photo transect method2024-09-09
  Research Overview Because coral reef ecosystems face human activities and climate change threats, coral reef conservation programs are implemented worldwide. Monitoring coral health provides references for guiding conservation activities. However, current labor-intensive methods result in a backlog of unsorted images, highlighting the need for automated classification. Few studies have simultaneously utilized accurate labels along with updated algorithms and datasets. This study aimed to create a dataset representing common coral reef conditions and associated stressors in the Indo-Pacific. Concurrently, it assessed existing classification algorithms and proposed a new multilabel method for automatically detecting coral reef conditions and extracting ecological information. A dataset containing over 20,000 high-resolution coral images of different health […]

  30th anniversary of the opening of the Penta-Ocean Construction Technical Research Institute at Nasu2024-09-05
  On September 5, 2024, Dr. Sasaki participated in the 30th anniversary event of the Technical Research Institute at Nasu, Penta-Ocean Construction Co., Ltd. It took about 15 minutes by shuttle bus from Nasushiobara Station to the institute. We visited the Penta-Ocean Museum and learned about the history of the company's development. The cutter head of the dredger used in the dredging of the Suez Canal is a highlight. Model of a dredger (the tip extending to the lower right is the cutter). Cutter attached to dredger. 30th Anniversary Lecture

  Participated in a talk show at the Zushi Sailing Festival2024-06-02
  I was invited by Prof. Tajima at UTokyo-Hongo, who is working on coastal erosion issues in Zushi Bay, Kanagawa, Japan, to be involved in some of the studies on the restoration of the seagrass and seaweed beds and environmental conservation in the bay. I was invited to participate in a talk show at the Zushi Sailing Festival on June 2, 2024. The north side of the beach has been eroded by longshore sediment transport from north to south, and rocky substrates have appeared. Sand is deposited on the south side, and a sand-bypassing is being implemented to return it to the north side, but cost is an issue. Other measures, […]
