 Institute for Biomedical EngineeringOpen OpportunitiesIn this project, you will be at the forefront of developing a new microrobotic system based on focused ultrasound trapping to treat ischemic strokes. In recent years, the development of microrobots has emerged as a promising frontier in precision medicine. These miniature robotic agents hold tremendous potential, yet their successful validation in vivo and their translation into clinical applications have encountered significant challenges. A primary impediment lies in the intricate task of precisely releasing therapeutic agents at the target environment. Previous approaches mainly made use of photocleavable links to release bound drug molecules at the target are. Unfortunately, light-based approaches often fall short in penetrating deep into tissue limiting the applicability in real medical scenarios. On the other hand, drug release via acoustic methods such as ultrasound has seen promising advancements by the use of bubbles or liposomes. However, our current microrobots rely on focused ultrasound trapping-based navigation and optoacoustic or ultrasound imaging. The occurring pressures in this method limit the use of bubbles or liposomes since they tend to collapse in this scenario. We are therefore searching for motivated students, who like to work on new concepts for the drug release in microrobots navigated via focused ultrasound. - Biochemistry and Cell Biology, Biotechnology, Chemical Engineering, Chemistry, Medical Biochemistry and Clinical Chemistry, Pharmacology and Pharmaceutical Sciences

| The remarkable complexity of morphogenesis and tissue regeneration implies the existence of a transcellular communication network in which individual cells sense the environment and coordinate their biological activity in time and space. To understand the fascinating ability of tissue self-organization, comprehensive study of biophysical properties (cellular nanomechanics such as tension forces and bioelectromagnetics) in combination with the analysis of biochemical networks (signaling pathways and genetic circuits) is required.
In this framework we are investigating the unacknowledged key role of Desmoglein 3 (Dsg3) as a receptor involved in mechanosensing, capable of initiating a signaling response in the transcellular communication network, which results in stem cell fate conversion, plasticity and tissue repair.
Our goal is to apply innovative Fluidic Force Microscopy to measure altered biophysical parameters upon disruption of Dsg3 transadhesion such as cell stiffness, cell-cell adhesion, cell surface charges and electric potentials. Together with the University of Bern and University of Lübeck we are further investigating how these biophysical changes relate to transcriptomic, epigenomic and proteomic response circuits to ultimately infer biophysical and biochemical circuits involved in Dsg3 signaling.

| Cardiac diffusion tensor imaging (cDTI) provides information about the cardiac microstructure by measuring the diffusion of water molecules within the heart wall. Current imaging standards measure three slices distributed across the left ventricle. However, if not corrected, respiratory motion causes slice misalignments that obstruct microstructure inference. Yet, this motion might also allow us to estimate sample points between slices, thus adjusting for motion and increasing spatial coverage. By using the respiratory navigator data, you will map in-vivo cDTI data to a 3D digital twin mesh and implement a tensor estimation to estimate sample points between slices based on spatial smoothness regularization. You then perform an accuracy evaluation on simulated data. - Biomedical Engineering, Human Biophysics, Medical Physics
