Åsa Konradsson Geuken

My research focuses on finding new treatments that could reduce the recurring psychoses, increase the quality of life and longevity of patients with schizophrenia. The purpose of my studies is to use unique techniques to clarify how drugs, drug candidates and new combinations of molecules affect higher cognitive processes in the brain. These studies may increase our understanding of the neurobiology behind schizophrenia and thereby facilitate the development of new effective drugs.

Åsa Konradsson-Geuken has considerable expertise in experimental neuropsychopharmacology, animal models of psychiatric disease, electrophysiology in vitro, cognitive tasks and several techniques for neurochemical analysis. She is one out of three researchers in Europe that use the enzyme-based microelectrode array in freely moving animals, and combines this with optogenetic techniques. Her focus is the neurochemistry in the neuronal networks involved in cognitive symptoms found in severe psychiatric diseases, i.e. schizophrenia.
