Stephen Dela Ahator

Job description

Stephen Dela Ahator is a researcher in the Drug Transport and Delivery Research Group within the Department of Pharmacy. His work focuses on the development of liposomal nanoparticles for the targeted delivery of biologics including peptides, nucleic acids, and proteins, primarily for pulmonary administration and thrombotic cell targeting.

Stephen’s long-term research vision is to integrate his expertise in cell and molecular biology, drug development and delivery systems, and computational science to better understand the dynamics of infectious diseases and overcome barriers in targeted drug delivery. His goal is to contribute to the development of effective therapeutics for complex infections and diseases. He is passionate about advancing innovative strategies that bridge biology and technology to improve treatment outcomes and expand access to precision medicine.

    Research interests

     

    Drug Transport and Delivery Systems
    Focus on the design and optimization of advanced drug delivery platforms, including liposomal nanoparticles and targeted carriers, to enhance the bioavailability and therapeutic efficacy of biologicals
    Computational Biology and Omics Integration
    I apply computational tools and systems biology approaches to integrate multi-omics data (genomics, transcriptomics, chemo/proteomics, and metagenomics) for a holistic understanding of disease mechanisms.
    Microbial Genetics, Sociomicrobiology, and Evolution
    Keen on investigating microbial behaviour, genetic adaptation, and community interactions, with a focus on antibiotic resistance, quorum sensing, and biofilm formation.
