I have two-year training and nearly two decades of professional experience in graphic design (print and online) and web development. I have also taught how to Design more effective scientific figures (see the teaching slides).
This includes data figures, diagrams and maps for journal publication, e.g. I adviced numerous authors at Nature Sustainability to improve their figures. Also posters and text documents, among others.
I apply sound, effective visual principles (e.g., by Tufte).Contact me for more examples, to ask for advice about work you have already drafted, or to develop full pieces. Write to firstname.lastname@example.org.
