Royhaan is a lecturer of anatomical sciences at the department of Anatomy, Olabisi Onabanjo University, where he also elucidates - in the Neurophytotherapy research unit - the developmental mechanics of psychotic and neurodegenerative disorders. This he does in a bid to identify therapeutic alternatives to the detrimental antipsychotics and neuro-palliatives currently obtainable.

He is a beneficiary of neuroscientific travel grants by bodies like Schizophrenia International Research Society (SIRS), International Brain Research Organization (IBRO), Teaching and Research in Natural Sciences for Development in Africa (TReND), and International Society for Neurochemistry (ISN). He is also a member of several professional bodies locally and internationally.
