Marcus Voß
Artificial Intelligence, Time Series, AI and Sustainability
I am an AI expert and consultant at Birds on Mars, from where I have experience in working on implementing AI proof of concept projects (time series, optimization, computer vision), getting AI into production, and enabling companies and people within companies to use AIs. Before, I worked in research on analyzing energy time series data. I am passionate about teaching data science and AI topics to different target groups. So, on the one hand, in company training formats or on the other hand, as an external lecturer, for instance, at TU Berlin Summer University, the Climate Change and AI summer school, Hertie School, CODE University of Applied Sciences, and Leuphana University Lüneburg. On the domain side, I am interested in all applications of AI and data in sustainable, environmental, and climate change-relevant applications.

Katharina Rasch
Data consulting, data analysis, programming, computer vision
I have been working as a freelance data scientist for both small startups and large corporations since 2017. In my projects, I like to get involved in product questions (what problem do we actually want to solve exactly and why?), but I am also mainly responsible for the technical implementation. Thanks to years of volunteer work, I have a lot of experience talking to community-based and non-profit organizations about data and developing sustainable data strategies. For organizations looking to build their own data skills, I’m also happy to provide training and mentoring.
