Role in the Centre
Sandra is an organic chemist with experience in photochemistry, physical-organic chemistry, and supramolecular chemistry. Her skills in synthetic chemistry and a wide range of analytical techniques like NMR spectroscopy are a valuable addition to the Soft Matter Materials Laboratory. Within QUT’s Centre for Materials Science, she uses her specialist knowledge of photoswitches to discover new light-induced ligation reactions to create new structures and translate this to a macromolecular level.
Sandra received her Bachelor of Science in Chemistry and Biochemistry in 2010 and her MSc in Chemistry, majoring Organic and Inorganic Chemistry in 2013 from Ludwig-Maximilians-University, Germany. She completed her PhD degree in 2018 with the highest rating ‘summa cum laude’ under the supervision of Prof Dr Henry Dube in Organic Chemistry, Photochemistry and Supramolecular Chemistry at the Ludwig-Maximilians-University. During this time she developed and synthesized new hemithioindigo photoswitches and molecular tweezers and published several high-impact papers. She then became a Postdoctoral Fellow in the Soft Matter Materials Laboratory at QUT, investigating new materials for lithography. In 2019, Sandra was selected for MAGIC 2019, one of 40 early career women and gender diverse researchers selected to participate in mentoring and leadership development. Further, she currently supervises HDR students and actively collaborates with various international groups.
