Ice Nucleation Colloquium

The virtual Ice Nucleation colloquium is a international platform to share and discuss current research around ice nucleation processes in the atmosphere. Research is presented in a Zoom-meeting as 30 to 45-minute talks, followed by a 15 to 20-minute Q&A-session. Succeeding the colloquium, the virtual meeting room remains open for informal discussions and networking of attendees. All scientists are most welcome to share their work, independent of their current academic career position. Hence, we aim to ensure equal representation of professors, senior scientists, postdocs, undergrad, and graduate students as well as talks about laboratory, field, and modeling research. Presentations about work in progress are specifically encouraged. If you would like to present at a colloquium, just send us an e-mail!
