Yousuf Mohammed

Associate Professor Yousuf Mohammed is a prominent researcher in pharmaceutics specializing in skin drug delivery at the University of Queensland. He earned his Doctor of Philosophy in pharmaceutics and skin drug delivery from Curtin University of Technology, supervised by Associate Professor Heather Benson, Professor Michael Roberts, and Associate Professor Tarl Prow. He also holds a Master's degree by coursework from Curtin University of Technology. Since 2012, Mohammed has been based at the Therapeutics Research Centre within the University of Queensland School of Medicine, progressing to Associate Professor and Senior Principal Research Fellow in the School of Pharmacy and Pharmaceutical Sciences. His career encompasses leading investigations into skin penetration, toxicology of topically applied drugs and nanoparticles, and critical quality attributes of semisolid formulations.

Mohammed's research has significantly influenced regulatory standards for topical and transdermal products. As Principal Investigator, he managed US FDA-funded projects including 'Bioequivalence of Topical Products: Elucidating the Thermodynamic and Functional Characteristics of Compositionally Different Topical Formulations' (2018-2023) and 'Bioequivalence of Topical Products: Elucidating the Sensorial and Functional Characteristics of Topical Formulations' (2019-2023). He served as Co-investigator on 'Characterization of Critical Quality Attributes for Semisolid Topical Drug Products' (2014-2019). These efforts aim to enhance guidelines for generic topical products through studies on API-excipient-skin interactions, rheology, texture analysis, and sensorial properties. Notable publications include 'Solute–Vehicle–Skin Interactions and Their Contribution to Pharmacokinetics of Skin Delivery' (2025, Pharmaceutics), 'Effect of “In Use” Administration on Topical Product Metamorphosis and Skin Permeation of Acyclovir Creams: Implications for Bioequivalence' (2024, Pharmaceutical Research), 'Advances in Characterization of Transdermal and Topical Products Using Texture Analyzer Systems' (2025, AAPS PharmSciTech), and 'Stimuli-Responsive Smart Nanocarriers for Skin Drug Delivery' (2025, International Journal of Pharmaceutics). He supervises multiple PhD candidates on advanced delivery systems and next-generation sunscreens. His contributions to nanoparticle safety in sunscreens have been featured in over 400 media articles, bolstering public confidence in sun protection.
