Umm.. yes that is my goal to get a PhD.
1) I have research experience just by what I had to research for my last graduation project. For example, studying about microcontrollers, programming and VB and designing the circuits. I will ask my undergrad advisor to mention this if he agrees. I have no publication and I feel that this can be a setback.
2) I am asking my professors, advisors, the place I did internship from to provide me LoR.
3) Regarding SoP, I intend to mention about my experience in graduation project and how its inspired to carry on in the instrumentation side of BME.
I am going to take GRE in July and I hope to do the best at it atleast in Quantitative section.
Thank you for your reply.
