Study path - electrical and automation engineer

Dear TWN Members, Hope you're well. I recently enrolled in urban sewage water treatment course offered by TUDELFT on EDX and I succeeded in completing the course. I am also an experienced electrical and automation engineer having worked in the water treatment industries for almost 8 years . I am currently unemployed and wanted to keep my skills sharp  so that I can find a job once corona is over. Having completed the course now , I am interested to pursue another course or one year plan that will help me . I am reading a lot on artificial intelligence ,machine learning and would like to know if you have such program along with water subject . Therefore I could combine my expertise , electrical and automation skills to advance my career . Would you please guide me by suggesting the best  study path , course to undertake knowing that I have time and good finances. Thank you in advance for your reply and help . Kind Regards Georges Feghaly
