Hello PF inhabitants, I have just finished 5 years of university culminating in a Master's degree in biomedical science. I now work in a genetic diagnostics lab. Problem is I always had a deep 'urge' to do something quantitative and I always liked the seemingly inapplicable aspects of maths/physics (at least from what I have been exposed to in layman science books). I am considering retraining in maths/physics/programming but this will be a complete u-turn for me. I know some of you are knowledgeable in physics into finance transitions and wonder what is your opinion on such a career path change? Also, if I went all the way to do PhD in physics, would I be too 'old' to get into entry-level roles in finance if I am unable to find a position in academia? I am 24 now, and at the soonest I would start my new degree next year. I feel like completely retraining would put me at a major disadvantage when I start looking for jobs due to my age. Any opinion or comments would be much appreciated.
