25 Postdoctoral Fellowship at Delft University of Technology (TU Delft), Netherlands

This project aims to create high resolution 3D images of optically cleared clinical tissue samples (e.g. biopsies) with optical diffraction tomography (ODT) for clinical diagnosis. The research will involve work on the biochemistry of optical tissue clearing and imaging of (clinically relevant) tissues using an existing set-up. The post-doc will perform proof of principle experiments that show the potential of ODT for 3D digital imaging of large volume tissue resections, compare the results to conventional histology, and translate the results to a clinical environment.  

The researcher will work in a team of experimentalists and theorists who share the common goal to imaging at the nanometer scale. She/he will work on simulation/theory of image formation and parameter estimation. The image formation description is based on the so-called 4pi microscope where the self-interference of the fluorescent emission can be used to estimate the axial position of a single emitter with nano meter precision. To this end the emission light is split into 4 channels (by polarization beam splitters) and the respective intensities are indicative for the axial position. As long as the emitter is free to rotate during one camera frame, a rotational symmetric point spread function (PSF) will be recorded, but if the emitter is fixed (due to conformational embedding or freezing of the medium) the PSF will reflect the dipole character of the emission and will depend on the 3D orientation of the single molecule emitter. In addition (field dependent) aberrations will influence the shape of the PSF. This requires the estimation model to reflect the forward imaging process perfectly and include all relevant parameters, such that a fit with many free parameters still converges. We want to build on our expertise in (maximum likelihood) estimation theory in combination with Cramer-Rao lower bound analysis to find the best way to tackle the problem at hand. Based on the results, we can set requirements on the tolerances for e.g. the alignment of objectives and the beam path to ensure at the end the most optimal localization precision.

The researcher will work in a team of experimentalists and theorists who share the common goal to imaging at the nanometer scale. She/he will work as an experimentalist designing and performing experiments with cryo fluorescent microscopy. In order to achieve very high spatial resolutions from single molecule emitters in 3D will be use a so-called 4pi setup with two opposing objectives. In addition the wavefront of the light must not be disturbed by optical aberrations. In reality such aberrations are always present, but only at our targeted high resolution at cryogenic temperatures, do they play a crucial role. Therefore the candidate will incorporate adaptive optics instrumentation and algorithms to measure the wavefront distortion and subsequently correct the distortions. 

IoT sensor nodes should have minimum form factor, low cost, accurate, and requires minimum maintenance, therefore, ideally environment powered. Getting sufficient energy from the environment then requires energy harvesters such as PV cells and highly efficient power converters. Such power converters must provide accurate MPPT, high conversion efficiency with a large power dynamic range, and a wide conversion ratio with minimum power consumption. Meanwhile, multi-input and output topologies will be preferred since they enable the use of multiple energy resources.

Medio 2022, the Pandemic Prepardeness programme through ventilation (P3Venti) was created to develop knowledge on the role of airborne transmission of viruses and other pathogens, and on the effectiveniss of ventilation as mitigation measure. As Postdoc within the group Indoor Environment, you will be working on research line III of the P3Venti programme, which is concerned with the impact of ventilation on airborne transmission, specifically in longterm healthcare facitlties. The aim is to study the effect of different ventilation regimes on the infection risk through experimental research in the Experience room of the SenseLab in combination with modelling activities. The research will be performed in close cooperation with the Adaptive consortium executing the P3Venti programme lead by TNO and the frontrunner project Airborne transmission and ventilation in the PDPC (Pandemic and Disaster Preparedeness Centre), created in 2021 by Erasmus MC, TU Delft and Erasmus University Rotterdam. The aim of this frontrunner project is to develop methods to predict and quantify the airborne transmission potential of viruses, based on model studies, experiments and outbreak research, that may lead to novel and improved mitigation strategies.

The project will focus on handling statistical inverse problems with non-Gaussian priors. Gaussian process priors are often used in practice due to their fast computational properties. However, the smoothness of the resulting estimates is not well suited for modelling functions with sharp changes, met for ecample in imaging. As an alternative for Gaussian priors one can consider Besov priors that are well suited for producing piecewise smooth reconstructions and for edge and interface detection.

The Digital Twin for Green Shipping (DT4GS) is a Horizon Europe project with over 20 industry and university partners aimed at delivering an “Open Digital Twin Framework” for shipping companies and waterborne industry actors to tap into new opportunities made available through the use of Digital Twins (DTs). DT4GS will enable shipping stakeholders to embrace DT innovations to support smart green shipping in the upgrade of existing ships and new vessels. DT4GS will cover the full ship lifecycle. Applications will focus on shipping companies but will also provide decarbonisation decision-support system for shipyards, equipment manufacturers, port authorities and operators, river commissions, classification societies, energy companies and transport/corridor infrastructure companies. DT4GS’s objectives are to:

The technology to support autonomous short-sea and inland vessel navigation has been actively developed and successfully demonstrated in several recent research projects. However, several technical challenges remain: 1) the lack of standardization that leads to adhoc, time-consuming, and costly vessel approval, 2) too strict requirements for system redundancy (e.g., multiple backup systems) to acquire type approval, which is a significant cost driver, 3) unclear liability assignment in case of an accident that may lead to increased insurance costs for all, 4) increased uncertainty with respect to how autonomous vessels will safely interact with conventional, crewed vessels, especially in high traffic situations25, exacerbated by thefact that COLREGs currently intended for human interpretation are too vague the Guidance, Navigation, and Control (GNC) schemes for autonomous vessels.

The EU aims to have a net-zero greenhouse gas (GHG) economy by 2050. At present, heating and cooling represent around 50% of the final energy use in Europe and are mainly supplied by fossil fuel derived energy. Because sustainable heat is mainly available in summer and demand is high in winter, large scale seasonal heat storage is a key strategy to decarbonize heating in order to achieve EU ambitions. TU Delft leads a large European project that will showcase and develop full-scale application of heat storage (up to 90°C) in geothermal reservoirs using three different technologies: Aquifer, Borehole and Mine Thermal Energy Storage (ATES, BTES, MTES), at 6 different sites in Europe which together represent a relevant range of geological conditions across Europe. In this PD project you will contribute to the development and application of a generic, open-source, high-performance and highly scalable framework to assess the Levelized Cost of Energy/Heat – LCOE reduction and carbon emission reduction costs (CRC) of heat storage in geothermal reservoirs in combination with different heat supply sources.
