Scientific Program

July 9 (Sun)
15:00-18:00Young Investigator Forum
Students in any aspect of carotenoids are invited to join the International Carotenoid Society and be eligible for travel awards to attend and present their work at this Young Investigator Forum. Students need to be members of the ICS (student membership is just $10 at and register normally and submit their presentation abstract (closed) by the student deadline of Feb. 28, 2023, indicating that it is to be considered for the competition. The organizer will inform you whether oral or poster later. There is no set number of awards, this will be determined by the quality of the abstracts. Take advantage of this program at your first opportunity to meet and discuss with top carotenoid scientists from around the world and we’ll see you in Toyama! Of course you can submit any abstracts for normal Oral & Poster Presentation as well.
