On October 15, we had the pleasure to welcome Dr. Kristina Beblo-Vranesevic, a former PhD student of our Faculty who completed her PhD under the supervision of Prof. Reinhard Rachel and is now working at the German Aerospace Center (DLR). She gave an inspiring guest lecture with the title “Life at the Limits: Microbes Beyond Earth.”

At DLR, Dr. Kristina Beblo-Vranesevic works in the interdisciplinary field of aerospace microbiology, investigating the emergence, development, and adaptability of microbial life under diverse and extreme environmental conditions. Her research explores the limits and requirements of life, including the possibility of microbial survival and adaptation in environments found on other planets and moons within and beyond our Solar System.

Combining laboratory studies, field investigations, and space-based experiments, her work examines how microorganisms and microbial communities respond to environmental stressors. This includes investigating microbial processes under controlled laboratory conditions, naturally adapted microbial communities, and microbial responses to space conditions and simulated planetary environments, such as those on Mars and icy moons. Another focus of her research is the role of microorganisms associated with the human body and their relevance for life in closed habitats and future long-duration space missions.

Before the lecture, Dr. Kristina Beblo-Vranesevic joined us for an informal coffee session, which was attended by many interested students and PhD students. This provided a wonderful opportunity to learn more about DLR's various research projects, as well as potential internship and career opportunities. Her open and friendly personality created a relaxed atmosphere and encouraged engaging and enjoyable discussions.

The event concluded with a relaxed dinner at Unikat, offering further opportunities for scientific exchange and personal conversations.

We would like to thank Dr. Kristina Beblo-Vranesevic for her fascinating insights, her openness, and the time she spent with us. It was a pleasure to welcome her back and learn more about the exciting field of aerospace microbiology!
