Sandra Wiedbrauk

Dr. Sandra Wiedbrauk is a Research Fellow at Queensland University of Technology's School of Chemistry & Physics, Faculty of Science. Her research bridges organic chemistry, photochemistry, and materials science with significant applications in UV sensing, antibacterial compounds, and functional materials development.

Dr. Wiedbrauk completed her academic training at Ludwig-Maximilians-Universität München in Germany, earning a Bachelor of Science in Chemistry and Biochemistry (2007-2010), Master of Science in Chemistry (2010-2013), and Dr. rer. nat. (Ph.D.) in Organic Chemistry (2013-2018). She has been a Postdoctoral Fellow at QUT since 2018.

Her research expertise spans several interconnected areas:

• Molecular photoswitch design and characterization, particularly hemithioindigo and diarylethene derivatives
• Polymer chemistry with applications in functional materials
• Photochemistry and light-responsive molecular systems
• Nanotechnology applications in UV sensing and detection
• Development of antibacterial compounds targeting biofilm-related infections

Analysis of Dr. Wiedbrauk's recent publication record reveals a clear evolution from fundamental photochemical studies toward increasingly interdisciplinary applications. Her early work (2014-2017) focused on the photophysical properties of hemithioindigo photoswitches, while her more recent research (2020-2024) demonstrates a strategic shift toward practical applications including wearable UV sensors, 3D printed colorimetric detection systems, and novel antibacterial compounds. A notable trend is her growing collaboration across disciplines, with recent co-authors from design, engineering, and health sciences reflecting the translational nature of her work.

Dr. Wiedbrauk's research has significant implications for developing practical solutions to health and environmental challenges, particularly in sun protection technologies and antibacterial treatments targeting biofilm-related infections that are increasingly resistant to conventional antibiotics.
