Nektarios Valous
computational scientist, journal editor, hobbyist photographer
About
I am working at the German Cancer Research Center (DKFZ) and the National Center for Tumor Diseases (NCT) Heidelberg. I am located at the Center for Quantitative Analysis of Molecular and Cellular Biosystems (Bioquant).
I am founding editor (link will be available shortly, following changes to the journal website) and executive editor of the open access peer-reviewed journal ImmunoInformatics (Elsevier). Editorial board member of Applied Sciences and AI in Medicine.
You can check my profile on: LinkedIn, Google Scholar, ResearchGate, ORCID, Scopus, and Web of Science.
I am a hobbyist photographer (also on Facebook and Instagram).
