Research Focus

My research approach spans from bench to bedside, bridging the gaps between fundamental and clinical research. My lab is interested in understanding the pathophysiology of mental diseases and over the years has discovered new treatments and cures for them. We have demonstrated in animal models and in humans that the long-term use of cannabis in adolescence can lead to depression later in life. We have also discovered and patented novel selective agonists of the melatonin MT1 and MT2 receptors for treating pain, insomnia, and anxiety. Recently, we published and patented research unveiling the mechanism of action of LSD and psychedelics in social anxiety and post-stress anxiety.
