Anna Stina Sandelius pursued her PhD degree in Plant Physiology with Prof Conny Liljenberg at the University of Gothenburg. She graduated in 1983 and spent the following year and a half with Prof D. James Morre at Purdue University in West Lafayette, Indiana, USA. She returned to the University of Gothenburg in 1985, where she attained full professorship in 1999. She is presently vice dean of the science faculty. As a graduate student, she studied the role of galactolipids during chloroplast development. She then switched to the plasma membrane and its lipid metabolism and supply, initially focusing on inositolphospholipids. The interest in lipid trafficking brought back plastids as an object of study and, thanks to her group's recent discovery that the plasma membrane uses plastid-synthesized galactolipids to replace phospholipids during phosphate-limiting cultivation, the two objects of study, along with the endoplasmic reticulum, have been brought together in efforts to elucidate lipid trafficking between plastids and the plasma membrane. Henrik Aronsson pursued his PhD degree in Plant Physiology with Dr Clas Dahlin at the University of Gothenburg. He graduated in 2001 and spent the following year and a half as a postdoctoral student in Dr Paul Jarvis' group at Leicester University. The next year he spent at Gotland University and Skovde University as senior lecturer. He then returned to the University of Gothenburg in 2004, where he attained associate professorship in 2007. As a graduate student, he studied plastid protein targeting of the light-dependent enzyme NADPH: protochlorophyllide reductase (POR) both to the envelope and the internal membrane system. He then switched to studying the chloroplast protein import machinery with a focus on the components that make up the machinery. His group has recently started studying the plastid vesicle membrane trafficking between the envelope and the internal membrane system with emphasis on putative proteins involved in the process.
