Friday Light Talks





 Friday Light Talks is more than just a series of scientific presentations. It is a supportive community of early career researchers, brought together by a shared passion for knowledge and connection. Hosted by physicists working in quantum optics and nanophotonics at Humboldt University, these regular events provide a welcoming context for students and young researchers to meet, interact, and learn from one another over a drink. Whether discussing scientific topics or exploring issues of career development, mental health, and diversity in academia, the Friday Light Talks are a platform for empowering the next generation of scientific leaders.


Format: 20-30 min presentation followed by a get together with drinks

Where? At the Physik Institute - NewtonStr. 15, 12489.

The talks take place either at the Main Lecture Hall or at Room 1,202, depending on availability. The room is announced together with the speaker previous to each talk.

When? Every second Friday at 5pm

Day of Light


 In occasion of the UNESCO International Day of Light, we are hosting Danilo Flores, co-founder of Mimotype, a Berlin based startup developing bio-inspired materials for ambient light sources. He will tell us about their scienceprenuer journey and will drive into the dark side of light bulb industry.

Mental Health in Academia


Katharina Bögl (Scholar Minds, Charité) and Luisa Esguerra (PhD student) will introduce us to the often-overlooked topic of mental health challenges among PhD and postdoc. With this event we aim to provide a safe and supportive space to initiate a dialogue and encourage open discussions to work together towards creating a healthier academic community.
