I resumed studying English this year because I have opportunities to use it at work. Basically reading and writing skills are sufficient for my current job, but I may have meetings with associates from each country. My job is to do regulatory affairs in a medical device company such as preparing for EU submissions, providing documents required by authorities in each country and assessing regulatory impact when we want to change the manufacturing process or materials of existing products. Since I started to work in the medical device field this year and my previous job was irrelevant to regulatory affairs as well as medical devices, I do not have enough vocabulary for the conversation. Writing down what I do at work is a good practice to learn vocabulary.
