Employed as curator at the department of phanerogamic botany, Swedish Museum of Natural History, Stockholm, I am leading a team scanning type specimens for the Global Plants Initiative GPI. My responsibility also includes adapting our collection database to our web-interface Krypto-S.
In my research, I was previously working with the phylogeny of the campanulids, especially the order Asterales and the families Escalloniaceae and Paracryphiaceae. More recently I have turned to the small southern African genus Geigeria (Compositae). My special interest is integrating morphologic data (especially embryology) with DNA-sequence data. I did my Ph.D. (2002) at the former department of systematic botany, Uppsala university, under prof. Kåre Bremer, and my post.doc. (2002-2004) at Kyoto university with prof. Tobe Hiroshi.
Since 1984 I have been actively exploring caves in Norway, Sweden, Iran and Mongolia. Poland, Hungary, Wales, Czech Republic and South Africa are some of the other countries my interest in caving brought me to. In Norway I was involved in the discovery of Tjoarvekrájgge, the longest and second deepest cave of Scandinavia. As most other cavers I am interested in speleology, the science of karst and caves. Recently I initiated a biological inventory of fauna and flora in Swedish caves (Mörk mångfald or Dark Diversity), and am also involved in projects concerning biomineralization of Swedish speleothems, geometry of karst, and the exploration and mapping of Tjoarvekrájgge.
I am member of the editorial board of the Swedish cavers magazine Grottan (published four times per year by the Swedish Speleological Society SSF), chairman of SSF:s Science Committee and a member of the Norwegian Cave Rescue Service Norsk Grotteredningstjeneste ("Responseteamet").
