The Veening lab is interested in understanding fundamental processes in the pneumococcus, the main cause of community acquired pneumonia and meningitis in children and the elderly. Using a multidisciplinary approach, including quantitative single cell techniques, systems and synthetic biology, we address how pneumococci grow and divide and segregate their DNA prior to cell division. We are also interested in the role of phenotypic variation for pneumococcal virulence and antibiotic resistance development.
Insights obtained from our research will lead to a better understanding of the biology of Streptococcus pneumoniae and might result in new treatment strategies for pneumococcal infections.
The Veening lab strives to teach and perform research at the limits of current knowledge and, using state-of-the-art techniques, produce high-quality work describing and uncovering new pneumococcal biology. We aim to create and foster a professional, fun, creative, safe, inclusive and productive environment, where all members are empowered with the skills, knowledge and resources required for their projects and future careers. To do so, team members are expected to be ambitious, critical and take full responsibility for their projects in a supportive, collaborative and open culture.
