The molecular biology revolution that dominated the life sciences in the second half of the 20th century has given us an unprecedented ability to explore the behaviour of cells - the fundamental units of life - in terms of molecular processes within and between cells. Researchers in the Department of Cell and Systems Biology, combine many different high-throughput, cell imaging, and physiological methods to characterize and understand cellular and physiological processes in both model (Arabidopsis, Drosophila, Mouse, Zebrafish, Pseudomonads) and non-model organisms.
