We are excited to have the Working Groups activity returning at YAS25! This is an excellent opportunity for participants to engage deeply with their peers and contribute with new ideas. These collaborative sessions are designed to bring together participants from diverse backgrounds to discuss challenges, share ideas, and co-develop innovative solutions in the field of algae research and technology. Participants will be sorted into groups based on algae topics of interest with the aim of promoting a feasible concept or solution. Each group will be mentored by a senior and follow a standard ideation approach. On the last day of the conference, each group will present their key insights and innovative solution(s).
