A fully funded postdoctoral position in the field of mass spectrometry imaging instrument development is available in the research group of Dr. Ian Anthony at the Maastricht MultiModal Molecular Imaging (M4i) Institute, embedded in the Faculty of Health, Medicine and Life Sciences (FHML) at Maastricht University.

Mass spectrometry imaging (MSI) is an exciting technique that is gaining popularity in the fields of biomedicine and medical diagnostics for its ability to chemically image tissues without the use of labels. MSI produces images of the locations of biochemical compounds that can help us understand and even better diagnose diseases such as cancer. Combining MSI with immunohistochemistry (MSI-IHC) is a new and rapidly growing technique that also enables targeted imaging of proteins at high spatial resolutions and can greatly improve the quality of the images; with much higher multiplexing than for example immunofluorescence microscopy [1]. Unfortunately, typical MSI instruments are slow, limiting the throughput and field of view for MSI-IHC experiments. For example, it can take many hours or days to image 1 cm2 of tissue at a high spatial resolution. Last year, researchers at M4i developed fast mass microscopy (FMM), a technique that enables speeding up MSI more than 1,000 times — now experiments that would take a day can be done in a few minutes [2]. The development of FMM poses challenges and opens opportunities for instrument and method development, validation, and optimization. One such opportunity is pairing FMM with IHC, which has not been done yet. With FMM-IHC, researchers could feasibly image hundreds to thousands of tissues in the time it takes to image a single tissue now while providing highly relevant biological information.

This postdoctoral position will improve FMM instrumentation so that it is capable of robust, reliable, and validated use with IHC-prepared samples. In particular, you will use and develop new FMM instrument modifications, experimental procedures and instrument parameters, and possibly instrument control and data processing software for the use of IHC with FMM. This position will work within a team of dedicated researchers at the M4i Institute and collaborate with partners at Penn State and ETH Zürich. At M4i, you will have a partner postdoctoral researcher who is dedicated to improving and validating the IHC portion of FMM?IHC. In the second half of the project, you and your partner postdoctoral researcher will collaborate to conduct a large screening of many biological tissue samples to demonstrate and validate the combined FMM-IHC technology. You will present your findings at leading international conferences at least once a year and will publish in peer review journals with open access unlocked for all publications.

The postdoctoral position will be supervised by Dr. Ian Anthony and co-supervised by Dr. Sebastiaan Van Nuffel and Prof. Ron Heeren. The anticipated start date is spring 2023, but reasonable accommodations can be made for the right candidate. The funding for this position is provided by the Chan Zuckerberg Initiative (CZI) under the project title “Fast Mass Spectrometry Imaging for Immunohistochemistry”.
