Laura Leighton

Dr. Laura Leighton is a Postdoctoral Research Fellow in the mRNA Sciences group at the Australian Institute for Bioengineering and Nanotechnology (AIBN), The University of Queensland. Her research focuses on RNA biology, particularly the functional characterization of RNA molecules and their roles in cancer therapy and neurological processes. She leads the development of mRNA-based therapeutics for liver cancer, leveraging lipid nanoparticle (LNP) delivery systems to target intracellular cancer proteins.

Dr. Leighton holds a PhD from the Queensland Brain Institute (2021), where her work, supported by the Westpac Future Leaders Scholarship, explored small noncoding RNAs in fear-related learning and memory. She completed her postdoctoral training under Dr. Seth Cheetham at AIBN in 2023. Her educational background includes a Bachelor of Science and Bachelor of Science (Honours) from The University of Queensland.

Her research interests integrate molecular biology, neuroscience, and translational medicine, with a focus on RNA modifications (e.g., m6A), long noncoding RNAs, and the epigenetic regulation of memory processes. Key themes in her work include fear extinction mechanisms, synaptic plasticity, and the application of mRNA therapeutics in cancer treatment.

Dr. Leighton’s articles consistently explore RNA-driven mechanisms in memory and disease. Recent work highlights the role of DNA G-quadruplex structures in memory regulation, the interplay between stress hormones and sperm RNA dysregulation, and the synthesis of novel long noncoding RNAs (e.g., ADRAM) that drive fear extinction. Her findings bridge basic neuroscience and clinical applications, emphasizing RNA’s dynamic role in health and disease.

• Awards: Westpac Future Leaders Scholarship (2017)
• Grants: TdC Mid Career Grant (Targeting liver cancer with mRNA therapies), Prader Willi Syndrome Research Grant (2022–2024)

She is actively involved in supervising research students and contributes to the development of advanced drug delivery systems targeting liver cancers. Her lab is part of AIBN’s mRNA Sciences team, collaborating on projects that translate RNA-based discoveries into clinical solutions.
