Dr. Mohsen Ahmadi

Institution: Leibniz Institute for Plasma Science and Technology (INP Greifswald)

Academic background: Biochemistry and microscopy

General tools: OMERO, ADAMANT, MICRO META APP, eLabFTW

Use Case involvements: Microscopy and plasma medicine: FAIR concepts for microscopy data in plasma medicine in order to integrate imaging and domain specific data into OMERO.

Professional experience: I am dealing with image microscopy from plasma medicine in INP Greifswald (ZIK-plasmatis). I am a biochemist that join the NFDI4Bioimage to connect the image data microscopy to the OMERO platform by sharing our knowledge regarding the minimum data information for microscopy imaging, e.g., analysis, storage, work flow, etc. and plasma medicine, e.g., work flow, metatdata, etc.

Dr. Vanessa Fuchs

Institution: Heinrich Heine University Düsseldorf, Center for Advanced Imaging (CAi)

Academic background: molecular (plant-) cell biology, a lot of imaging/different imaging techniques

Professional experience: Data organization and metadata annotation in/with OMERO, Community use case (CUC) documentation and supervision, Helpdesk supervision

Dr. Riccardo Massei

Institution: Helmholtz Centre for Environmental Research – UFZ

Academic background: Environmental Sciences and Toxicology

General tools: OMERO, Python, KNIME, eLabFTW, FishInspector, JupyterNotebooks

Professional experience: I am a dealing with high-content screening (HCS) images collected from fish embryos, zoo-plankton and cell lines. I joined NFDI4Bioimage to apply/advise on FAIR-IO concepts for HCS data and provide semi(automated) integrative workflows for transferring analytical HCS into cloud based systems (i.e. OMERO).

Dr. Maximilian E. Müller

Institution: University of Konstanz, KIM, Team Open Science

Academic background: Biology and Environmental Siences

Professional experience: I administer the OMERO research data management platform at the University of Konstanz and work closely with researchers to develop user-driven solutions for bioimaging data management. I support the creation of data management plans, the publication of research data, and contribute to tools and services that facilitate FAIR practices. I am also involved in developing and delivering training in research data management for the bioimaging community.

General tools: OMERO, RDMO

Jens Wendt

Institution: Münster Imaging Network, University Münster

Academic background: Electrical Engineering/Information Technology, Biomedical Engineering

General tools: OMERO, Python, multiple image analysis platforms, starting to look into eLabFTW

Professional experience: Since 2021 lots of software development/customization around OMERO, Python and Image analysis tools. System administration and (meta)data management.

Dr. Cornelia Wetzker

Institution: Center for Molecular Bioengineering (B CUBE) TU Dresden

Academic background: Biologist by training in fields of molecular biology, immunology and zoology. PhD in basic cell biological research in the field of mitotic and meiotic cell divisions in mammals.

General tools: R, Python, napari, Fiji, OMERO

Professional experience: Long year experience in life science research with broad scope from cell biology throughout immunology, evolutionary biology and zoology combined with strong focus on imaging including fluorescence lifetime imaging microscopy (FLIM). 3-year experience as staff member of a light microscopy facility of the local campus including training of scientists and method development and image analysis. Recently shifted focus more towards data science and (image) data analysis and management in the life sciences.
