Hello! As of this week, I have left graduate school. I just completed my first year as an Astrophysics Ph.D. student, but between financial constraints and general unease within my program, I have decided to go another direction. I have a bachelors in Physics, and I have interned at Kitt Peak National Observatory in Tucson, AZ. I have worked as staff with the LSST (Large Synoptic Survey Telescope) development team. In graduate school, I was using VLA (Very Large Array) data to study AGNs (Active Galactic Nuclei). I am now looking to go into the business side of science, rather than the research side. Scientific research just wasn't my cup of tea. However, I have zero business experience and no business courses to back me up. I am interested in pursuing sales or marketing as it relates to my scientific background (so, for example, working as a sales rep for Toshiba, selling MRI units). Anyway, my question is this: What's my best course of action for gaining a background in business? Going back to undergrad for three or four years to earn a bachelors in business or a similar field is likely not an option. Taking supplementary business courses, though, while working part time may be an option. How do I approach taking supplementary courses? I really don't know how undergrad works if I'm not technically pursuing a degree. How would I add supplementary business courses to my CV in order to show potential employers that I have the business background, without a degree? Thank you for any help or suggestions!
