Dr. Mohsen Omrani is a medical doctor with a PhD in neuroscience and a postdoctoral fellowship in computational psychiatry. His clinical background and expertise in basic science research and data science led him to develop the Online PsychoTherapy Tool (OPTT), a digital-first psychotherapy platform, in collaboration with Dr. Nazanin Alavi, a staff psychiatrist at Queen’s University. Their goal was to develop a next-generation mental health platform, one that is based on objective evaluations and data-driven decision-making. Given their expertise in the field, Drs. Omrani and Alavi were commissioned by Springer/Nature, a leading publisher in the field, to write the first handbook on delivering online psychotherapy.
