Thanks for reaching out! Normally a 4 year work gap would be a deal breaker for b-school, and it is still going to be a bit of a challenge for you, but given your story & the oppression you faced from your father I think it's a challenge you can totally overcome. You'll want to be certain to tell that story to the adcom via the optional essay -- not just the oppression you faced, but how you finally overcame it & got that first job despite the obstacles. I think Ivy League schools will be a bit of a stretch given your GPA & GMAT, which are both a bit below average, but if you could improve your score to a 730 or 740 you'd have a shot at it. I think you do have a shot at US schools in the 15-25 range as well as ISB.
R&D can tend to be a role where it's difficult to show quantifiable impact of your work, which is a challenge as well - the adcom likes to see the results applicants have driven. So you'll want to do your best to show the business skills you have gained in that role as well as any results that you have driven.
If you'd like any help thinking through your strategy, definitely reach out to us. You're in a unique situation given what you faced from your father, and it will be critical to use that story to your advantage - to show that it's not about the work gap, it's about the perseverance you showed in getting to where you are now. If you'd like to chat, send Claudia a note at

You've demonstrated huge strength to get where you are & you can take this next step to make b-school a reality as well! It's just going to take some strategy to be sure you get into the best school possible.
