2. Topic: Mass spectrometry
Queensland University of Technology, Australia
Dr Hendrik Frisch received his PhD in Chemistry from the Institute of Organic Chemistry in 2016 at the University of Muenster, Germany. In 2017, he joined the Queensland University of Technology (QUT) as a postdoctoral fellow of the German National Academy of Sciences, Leopoldina to work with Prof. Barner-Kowollik on the development of light gated polymer ligation systems. Since 2020, he is a Senior Lecturer and ARC DECRA Fellow at QUT. Dr Frisch’s research program strives to unleash untapped synergy between peptide based macromolecular architectures and photochemistry to overcome chemical challenges under biocompatible conditions
3. Topic: Field Flow Fractionation
Colorado School of Mines, USA
Prof Kim Williams is working as a Professor of Chemistry at the Colorado School of Mines, Research-Advising Faculty in the Materials Science program, and Faculty in the Quantitative Biosciences and Bioengineering program. Her work with field-flow fractionation started with her postdoctoral at the University of Utah with the late J. Calvin Giddings. Her current research program can be broadly classified as separation science of nanometer to micrometer-size species. This includes a focus on developing field-flow fractionation (FFF) with light scattering and mass spectrometry approaches to simultaneously separate and characterize complex multi-component systems. More specifically, her research group has introduced new methods to measure distributions in nanoparticle surface composition and shape as well as difficult to analyze polymer attributes such as architecture and number of chain ends. Applications extend to materials for renewable energy systems and membrane, biotherapeutic proteins, and biological particles such as lipoproteins and extracellular vesicles for disease diagnostics.
