Elias Arnér, MD PhD, Prof./Head of Division


Elias was admitted as one of the initial ten students of the new MD PhD program at Karolinska Institutet in 1986. He completed his PhD in 1993 with studies on nucleotide metabolism, having Assoc. Prof. Staffan Eriksson as supervisor. In parallel with completing his medical studies Elias engaged in studies of mammalian thioredoxin reductase together with Prof. Arne Holmgren, which has since remained a significant research interest. During a post doc in 1998/1999 with Prof. August Böck in Munich, Germany, Elias studied the production of recombinant selenoproteins, which is another major field of research still conducted in the group. Elias returned to Karolinska Institutet in 1999 and in 2008 he succeeded Prof. Holmgren as head of the biochemistry division.

Pablo Martí Andrés, PhD, Post doc

Pablo joined the division in February 2021 after completing his international PhD in redox signaling in oxidative stress and acute inflammation, focused on the roles of thioredoxin 1 (Trx1) and thioredoxin-related protein of 14 kDa (TRP14). His current project aims at deciphering how essential trace elements Se, Cu, and Zn modulates redox signaling and oxidative defense in cancer cells, both in vitro and in patient samples. Understanding these complex interactions and their effects may lead to identifying new potential targets for drug therapy.
