Yousuf Mohammed

Associate Professor Yousuf Mohammed is a Senior Principal Research Fellow at the University of Queensland's School of Pharmacy and Pharmaceutical Sciences. With a PhD in pharmaceutics and skin drug delivery from Curtin University, he has led major US FDA-funded projects (2018–2023, 2019–2025) on bioequivalence of topical formulations, focusing on thermodynamic properties, sensorial characteristics, and critical quality attributes (CQAs) of semisolid products. His work bridges pharmaceutical science, nanotechnology, and clinical applications, impacting regulatory guidelines for topical drug products.

His research integrates

• bioequivalence studies of topical creams
• skin penetration and toxicology of nanoparticles
• instrumental characterization (rheology, tribology)
• metamorphosis of topical formulations during application
• 3D preclinical skin models
• microneedle and microprojection technologies

Recent publications highlight trends in

• sensorial-therapeutic equivalence
• nanoparticulate delivery systems
• UV protection safety
• skin enzyme metabolism of topicals
• computational approaches in drug repurposing

He supervises PhD candidates in formulation science and collaborates with international researchers on projects involving multiphoton microscopy, FLIM imaging, and regulatory innovation. His findings, particularly on zinc oxide sunscreen safety, have been widely cited in global media (>400 outlets), influencing public health messaging during Australian summers.
