Roger Marek

Dr. Roger Marek is a Research Fellow at the Queensland Brain Institute within The University of Queensland, affiliated with the Faculty of Health, Medicine and Behavioural Sciences. His work focuses on behavioural neuroscience, biological psychology, and fear memory mechanisms.

• Postgraduate Diploma in Neurosciences, University of Otago
• Masters (Coursework), University of Regensburg
• PhD in Neuroscience, The University of Queensland

His research explores neural circuits mediating fear, extinction, and memory. He investigates how brain regions like the amygdala, prefrontal cortex, and hippocampus interact to regulate emotional responses, using techniques such as optogenetics and in vivo electrophysiology. His recent publications highlight advancements in neurotechnology (e.g., multi-OLED devices) and the biological basis of fear relapse.

Key trends in his 15 most recent articles (2009-2023) include studies on fear extinction mechanisms, amygdala-prefrontal connectivity, optogenetic tools, and epigenetic influences on memory. These works span neuroscience, biomedical engineering, and molecular psychology.

• ARC Discovery Early Career Researcher Award (2020-2023)

Dr. Marek has supervised and advised PhD students at the University of Queensland, focusing on topics like amygdala-prefrontal connectivity and medial prefrontal cortex roles in memory. He currently holds a Brain and Behavior Research Foundation Open grant (2024-2026) for research on memory engrams driving fear relapse.
