About

Professor Lasse Riemann is a faculty member at the University of Copenhagen, Denmark. His research focuses on nitrogen fixation in marine environments, particularly in polar and coastal waters. Recent publications highlight his investigations into diazotrophic bacteria, plankton community metabolism, and the dynamics of vitamin B1 in coastal systems. Through long-term studies and isotope incubations, Professor Riemann contributes valuable insights into the ecological roles of microorganisms in global oceanic processes.
