Dr Geertje Van Keulen (she/her) is Associate Professor in Microbial Biochemistry in the Institute of Life Science at Swansea University.

She leads interdisciplinary research and innovation teams with microbiology at its core, expanding understanding into and sustainably exploiting the chemical and material properties of microbes in living, manufactured and natural (soil) environments. Her research links antibiotics, water repellency and materials, thereby switching focus between microbial to manufactured to soils with insights generated in one discipline quickly applied to another, and back, for generating step changes in knowledge and sustainable innovation. She is on the Academic Career Pathway in Enhanced Innovation and Engagement.

Geertje furthermore collaborates with hundreds of women in STEMM, especially through the public engagement and gender equality activities that she leads through Soapbox Science Swansea.
