Quantum infor­ma­tion process­ing with scalable semicon­duc­tor spin-qubit chips

Dominic Barthlott - Hector Fellow Wolfgang Wernsdorfer

Quantum computing has the potential to provide speedups for classical problems such as complex simulation, optimization and cryptography tasks, but requires scalable and reliable qubit technologies. Semiconductor spin qubits combine long coherence times with established industrial fabrication techniques. This project focusses on implementing high-fidelity two-qubit gates, which are then expanded to multi-qubit arrays and quantified by applying quantum information algorithms together with rigorous benchmarking.

Beyond the Cortex: Subcor­ti­cal Connec­tiv­ity in Social Cognition

Lorenz Ahle - Hector RCD Awardee Sofie Valk

This project explores how subcortical structures such as the amygdala, thalamus, basal ganglia, cerebellum and hippocampus shape social cognition. Using high-resolution fMRI, diffusion MRI and computational modeling it examines how connections between subcortex and cortex support empathy, perspective taking and emotional regulation.

Neural mecha­nisms of visual percep­tual learn­ing in children and adults

Dominik Aschenbrenner - Hector RCD Awardee Sebastian Frank

Visual perceptual learning (VPL) – a type of visual skill learning – has often been studied in adults as a model system to identify neural mechanisms of learning. However, it is unclear whether children employ similar neural mechanisms for VPL as adults. In this project, we will use non-invasive brain imaging to measure and compare neural mechanisms of VPL in children and adults and examine whether and if so how learning changes from childhood to adulthood.

Synthe­sis and Charac­ter­i­za­tion of biofunc­tion­al­ized organ­otin chalco­genide clusters

Martina Kämpfe - Hector Fellow Stefanie Dehnen

The cytotoxicity of organic tin compounds makes them interesting for cancer chemotherapy. Organotin chalcogenide clusters release under acidic decomposition not only an organic tin compound but also an even more toxic hydrogen chalcogenide. To enable biocompatibility of those clusters, they must be derivatized with biomolecules. This project aims to synthesize biofunctionalized organotin chalcogenide clusters and to investigate their decomposition behavior.

Mecha­nisms of mitochon­dr­ial protein translo­ca­tion and membrane biogenesis

Pragya Kaushik - Hector Fellow Nikolaus Pfanner

Mitochondrial protein import is mediated by the presequence translocase of the inner membrane (TIM23 complex). While Tim17 is central for inner membrane translocation, the exact role of Mgr2, a small transmembrane protein, remains unclear. This project aims to define the function of Mgr2 in precursor protein import, membrane insertion, and translocase stability using genetic, biochemical, and structural approaches.

Electri­cally Free Thermal Actua­tor for Preci­sion Control

Athira Kattiparambil Sivaprasad - Hector RCD Jingyuan Xu

Non-electric actuators offer a promising alternative for sustainable and remote operations. My research focuses on the development of thermal micro-actuators based on thermomagnetic thin films, which harness the intrinsic material property of magnetization loss near the Curie temperature to achieve controlled mechanical motion. Unlike conventional actuators that rely on electrical stimulation, these devices operate by thermal triggering, eliminating the need for continuous electrical input and thereby reducing power consumption.

tRNA thioepi­tran­scrip­tome: Regula­tion of protein synthe­sis in vessel development

Ioannis Theodorou - Hector RCD Sofia-Iris Bibli

This project investigates how sulfur-containing amino acids regulate tRNA thiolation in endothelial cells, thereby controlling protein translation during vessel growth. Mapping the human endothelial tRNA thio-epitranscriptome will uncover novel translational control mechanisms and lay the foundation for potential therapeutic strategies targeting pathological angiogenesis.

Inter-kingdom wound care between ants and plants

Melina Kienitz - Hector RCD Awardee Erik T. Frank

This project investigates the mutualism between Vachellia trees and Pseudomyrmex ants, focusing on their role in wound care. Using chemical ecology, proteomics, microbiology, and behavioral experiments, we plan to identify relevant wound healing compounds as well as the evolutionary mechanisms that enabled inter-kingdom wound care. This research expands on our concept of the social immune system by expanding it towards the ants’ host in this unique relationship.

Repre­sen­ta­tion Learn­ing and Causal­ity: Theory, Practice, and Impli­ca­tions for Mecha­nis­tic Interpretability

Florent Draye - Hector Fellow Bernhard Schölkopf

This research projec aims to contribute to the development of methods that extract informative and interpretable features from high-dimensional datasets, with a focus on uncovering high-level causally related factors that describe meaningful semantics of the data. This, in turn, can help us gain deeper insights into the representations found within advanced generative models, particularly foundation models and LLMs, with the goal of improving their efficiency and safety.

Inducible CRISPR gene editing systems for patho­genic USH2A variants

Salome Spaag - Hector Fellow Eberhart Zrenner

Amongst the leading causes of retinal dystrophies worldwide is Retinitis pigmentosa, a severe disease often caused by splice variants in the USH2A gene. This project aims to develop a safe CRISPR-based therapeutic strategy for correction of such splicing defects. Using enhanced-deletion nucleases, the disease-causing alterations can be eliminated, hereby restoring correct protein synthesis. The focus lies on safety features as well as the development of an inducible viral delivery system for clinical application.
