I've been a PhD student in a STEM field for less than year now. Before embarking on this journey, I was pondering between electrical engineering and computer science for my MSc studies, which I completed before starting a PhD (It was possible to branch from BSc to either field). However, even after completing a MSc degree and working on a PhD in electrical engineering, I still find myself intrigued by the field of computer science.
Would I be spreading myself too thin / hindering my PhD project severely if i started working on a master's degree (2 years) in computer science as a free-time hobby during my PhD studies? I have already completed some coursework related to the degree and there is some synergy between the fields.
I have a strong feeling that studies in computer science would be valuable in my future career. On the other hand, I do not know if I will have to increase my working hours on the PhD project at some point to the extent that I don't have sufficient "free-time".
I would like to hear if you have had similar experiences/plans and what did you do. thanks for reading!
