Dr. Bukhteeva took on the challenging task of uncovering the differential effects of Li isotopes on human ion transporters across multiple cell types during her PhD studies. Her work demonstrated that several ion transport mechanisms, such as the mitochondrial sodium/calcium/lithium exchanger, calcium phosphate clusters, and Na+ and K+ ion channels, are affected by Li isotopes. Furthermore, her work showed that significant Li isotope fractionation occurs at the mitochondrial membrane; however, only small effects were observed at the Na+ or sodium/calcium/lithium exchanger channel levels. Collectively, the PhD thesis work expands our current knowledge of Li therapeutic applications and provides a solid foundation for future experiments to elucidate the mysteries of Li and its isotopes.

Sophia Bird worked on a challenging project using analytical ultracentrifugation to characterize the composition of liquid therapeutics composed of protein-functionalized lipid nanoparticles (LNPs) loaded with mRNA cargo. As Sophia has shown in her paper published in Adv Functional Matter “High-Resolution Characterization of Protein-Conjugated, mRNA-Loaded Lipid Nanoparticles by Analytical Ultracentrifugation”, analytical ultracentrifugatoin in combination with D2O density matching, as well as a new computer program in UltraScan, allows, for the first time, lipid nanoparticle distributions based on molar mass, density, and hydrodynamic radius to be obtained using UV/visible detection at wavelengths largely unaffected by light scattering.

]]>The post Sarah Rauscher appeared first on Biophysical Society of Canada.
]]>Prof. Rauscher is internationally recognized for her contributions to computational biophysics, particularly in the modelling of intrinsically disordered proteins, protein allostery, and the development of molecular simulation methodologies. Her work bridges physics, chemistry, and biology, and is marked by rigorous statistical analysis, methodological innovation, and deep integration with experimental approaches. Her publications span top journals such as Nature Methods, Nature Communications, eLife, and Biophysical Journal, and have received over 8,400 citations to date, with more than 900 in 2025 alone. Her scientific leadership is evident in her development of new methods to analyze protein-water interactions and to model functional protein motions within crystals. These approaches have advanced our understanding of disordered protein behaviour, conformational transitions, and solvent dynamics in biological systems. Notably, her contributions to force field refinement and all-atom simulations have become foundational within the field.
Beyond research, Prof. Rauscher has demonstrated outstanding mentorship and service. She has supervised over 40 trainees across all levels, with her postdoctoral fellows now holding tenure-track positions in Canada. Her students and postdocs have received over 30 awards and fellowships. She has co-organized national scientific meetings, served on the editorial board of Biophysical Reports, and played a critical role in review panels for the Digital Research Alliance of Canada.

Research Summary:
The primary goal of our research is to understand in detail the structure-property relationship of protein-protein/ protein-ligand interaction networks.
The lab studies how the mesoscale architecture of extracellular and surface-associated protein assemblies encodes biological signaling, mechanics, and disease function. Our principal aim is to gain molecular insights to therapeutically impact human disease. We view structural and biophysical information here as molecular fingerprint for both basic and applied advances. To reveal the underlying mechanistic aspects of extracellular signaling hub formation, we use a combination of:
In 2014, the Center for Oil and Gas Research and Development (COGRAD) was founded as collaborative effort with the laboratory of Dr. Tomy. In this unique, ISO-certified Center powerful tools for live stock mapping and biodiversity monitoring are developed. In 2019, Dr. Stetefeld initiated the Center for Integrated Structural Biophysics (CISB) with the goal to provide a world-class platform for structure-based drug design projects. In 2024, White Otter Biotech Inc. started to provide eDNA/eRNA based biodiversity monitoring and environmental modelling approaches for industry and government clients.

Research Summary:
Our laboratory develops quantitative single-molecule and single-cell imaging platforms that integrate physical confinement with label-free interferometric scattering microscopy and multi-channel fluorescence imaging. Central to this work is Convex Lens-induced Confinement (CLiC), a technique enabling high-throughput, single-particle analysis without surface tethering.
We have outlined the conceptual and methodological framework for studying molecular interactions in cell-like environments using confined single-molecule imaging (Leslie et al., Current Opinion in Biomedical Engineering, 2019). Building on this foundation, we have demonstrated multiparametric characterization of individual nanoparticles using combined confocal fluorescence and interferometric scattering microscopy with microfluidic confinement (Boateng et al., Nano Letters, 2025) and extended this methodology to live-cell imaging (in
preparation, 2026).
By reducing sample requirements while increasing detection precision, our techniques expand the toolkit of quantitative biophysics and support applications ranging from nucleic acid biophysics to nanoparticle therapeutics and drug discovery. By striving to combine our single-molecule and single-cell imaging data with multi-scale biological data, acquired by working hand-in-hand with health scientists, we aspire to innovate new medicines and nanomaterials with functional properties that we understand across multiple scales
