The Maresca Lab introduces the nascent field of biomolecular ultrasound imaging, a molecular imaging approach that relies on genetically encoded acoustic biomolecules to interface ultrasound waves with cellular processes. They review ultrasound imaging applications bridging wave physics and chemical engineering with potential for deep brain imaging.

The Delphi Consortium is a collaboration between Applied Sciences and Civil Engineering & Geosciences and is sponsored by ~25 companies, traditionally from the oil & gas industry. Because of the increasing awareness of the negative impact of fossil fuels on the environment, it was decided to shift the focus to applications in the sustainable geo-energy sector. In January Delphi welcomed Fugro as a new sponsor. Fugro's interest is in near-surface characterization for constructions (offshore wind turbines).

From the 1st of March, Hylkje Geertsema started her tenure-track position within Imphys. Her position has a large focus on education and educational innovation in applied physics and nanobiology. At the same time, she will direct a small research group pursuing quantitative super-resolution microscopy on DNA replication proteins in human cells.

The Lifelong Optics Learning training platform has been set up for professionals in optics and photonics and offers practical, testable and modular education at MBO, HBO and Academic level. The platform is a collaboration between TU Delft, the Leidse Instrumentmakers School (LiS) and The Hague University of Applied Sciences (HHS). The project has been subsidized by the Dutch Ministry of Social Affairs.

Qian Tao joined the Medical Imaging group of ImPhys per March 1st 2021. She will direct the Knowledge-Driven AI lab (KDAI Lab). Her research interest includes medical image analysis, machine learning, and their state-of-the-art combination in theory and in practice.

By using a novel membrane-based optical cavity and a gold reflector, researchers from the Optics Research Group (ImPhys), together with collaborators from the Royal Institute of Technology (KTH, Sweden) and Single Quantum B.V. (Delft) have achieved a detection efficiency of 99.5%, with a time resolution of sub-20 picoseconds.

Quenteijn's master project is a collaboration of the Reactor Institute Delft (RID) and Imaging Physics (ImPhys). The research will be conducted in Elizabeth Carroll's lab and it will involve the irradiation of spheroids, staining them of damage and imaging the damage using light-sheet microscopy.

Baptiste Heiles, a postdoctoral researcher at the Maresca Lab (ImPhys), has received a Marie Skłodowska-Curie Fellowship from the European Union. Each fellow receives two years of stipend and a mobility allowance giving them the opportunity to boost their career abroad. His project, entitled Multi-messenger Imaging of Cancer aims to leverage early metabolic and vascular detection of cancer using ultrasound. His project was ranked in the top 0.3% of the Physics panel.

Hugo, Max and Hilke are working on computational projects where they model electrical dynamics in networks of excitable cells in different ways. Florine is helping us set up and optimize a microscope and imaging protocol for simplified in vivo voltage imaging in collaboration with the lab of Zhenyu Gao at Erasmus MC.

Thijs van der Burgt will be doing his master-end-project as part of the Nanobiology master programme. He will work under supervision of Daan Brinks and will create a robotic patchclamp setup for us to perform automated electrophysiological experiments.
