UXUI research and interaction course? [on hold]

I was checking this website out https://uxmastery.com/resources/ux-degrees/ because I am looking for a course to improve my UXUI Design skills. Currently I work as a UXUI designer and Front-End Dev with 3 years of experience. However, sometime I feel I have a lack of experience or knowledge in some areas, especially in UX research and interactive

I wonder if you know a course for people who already have some experience in this field and is working as a UXUI designer in order to improve my UXUI Design skills in general with a good focus on UX research and interaction.

Thanks
