Morten Kringelbach’s research goal is to reverse-engineer the human brain and in particular to elucidate the heuristics that allow us to survive and thrive. His focus is on elucidating hedonia (pleasure) and eudaimonia (the life well-lived), and how they are affected in health and disease; in particular, seeking to elucidate their breakdown in anhedonia (the lack of pleasure) in neuropsychiatric disorders.

Alexander Wieck Fjaeldstad is an MD-PhD who served as a Captain in the Danish army. After deployment in Iraq, he became aware of how certain smells can be potent triggers of memories from the battlefield. This link provides a unique window for examining how the brain processes these memories in veterans with and without PTSD. His research focuses on understanding olfaction in the brain and how this can be used clinically.
