If you want to learn to swim, take the plunge into the cold water.

Local Organisation: JCI Karlsruhe
First attended JCI EA: 2023

Since joining JCI in 2018, Lama has been an active and engaged member, holding various positions at different levels. In 2021, he became a JCI Germany Trainer, dedicating himself to empowering young members and future leaders. Passionate about personal development, Lama participates in JCI events on both national and international stages, enjoying the opportunity to connect with new and familiar faces while exchanging ideas about life, the universe, and everything.

Professionally, Lama transitioned from academia to the fast-paced world of AI startups (to be fair, he left academia in 2016…), where he supports his team in driving innovation. Not only does he work with cutting-edge technology, but focuses on applying AI solutions to real-world challenges and not just for the sake of it. As a member of the 2023 and 2024 COC teams, Lama is looking forward to shape the best academy ever in 2025!
