There isn’t a usual day to be honest. Yesterday I made a program to interpret data in excel. This morning I was in a meeting with process engineers all over the world and then spent the afternoon working with a simulation for fluid flow.
Other days I can be working in the pilot plant making samples or playing with machinery. There’s usually data analysis as there’s no point in trying things if you don’t learn anything from it. In a couple weeks in abroad for a factory trial of a new product in Turkey. Possibly in Germany for a conference the week after that. Very varied!!!
