Scientific Consultant (PhD) | Technical Writing, Research Support, Lab & Project Workflow Optimization

Profile Summary

I’m a physicist (PhD), scientific consultant, and founder of HeronSpecs, where I help research and engineering teams optimize their workflows through advanced lab and project management tools. I specialize in delivering clarity, structure, and efficiency to complex scientific and technical projects. I earned my doctorate from the Max Planck Institute for Extraterrestrial Physics, working on experimental physics, molecular spectroscopy, and radio astronomy. I have published in leading astrophysics journals and collaborated internationally with renowned research groups. Before founding HeronSpecs, I worked as a technical project manager and product owner for cryogenic systems and optical microscopes, leading cross-functional teams and supporting high-tech development projects. Earlier, as a patent engineer, I drafted applications in electron microscopy and advanced technologies, gaining deep experience in technical documentation and innovation processes. I bring strong skills in scientific writing, project planning, process optimization, stakeholder communication, and multilingual coordination. I am fluent in English, Greek and German, and I excel in cross-cultural collaboration and international project communication. In short here are the services I offer: Optimized Services: - Scientific consulting & technical strategy - Lab & project workflow optimization (Notion/Obsidian systems) - Technical writing (grants, EU deliverables, documentation, reports) - Literature reviews & research synthesis - Data analysis & visualization - Educational/training content development - Patent & innovation technical support (non-legal) Below you can find examples of my workflow tools, my freelance services and technical content. -My personal freelance website: https://johannachantzos.com -My lab and project management tools (HeronSpecs): https://heronspecs.com -Tool demo videos: Digital Lab Notebook – https://youtu.be/OTKdFrWFKVI Lab Operations Overview – https://youtu.be/uEKnyq-Snbg
