Here’s my situation.
I did an engineering major and have been in the industry for about 1.5 years. It is my goal to apply for engineering PhD programs next Fall. I did 2 research projects with 2 different supervisors. I also had a 3rd academic staff member that I worked part time with. I wanted to apply last year, but I informed my referees whom I had contacted at the end of last year that I would halt my application for another year before applying. They were quite happy to give me recommendations then.
I contacted again one of my supervisors a while ago and he said he would be happy to be one of my referees. Then just recently I contacted the same supervisor again and he said that he was quite busy and that it would be better to ask someone I am currently working with or recently worked with. I am at a loss on what to say and I haven’t replied to him yet. If I say something wrong, I fear that he might refuse to write me an LOR altogether. He supervised me for an undergraduate research project and he seemed very pleased at the end of the project. I am not even sure how my other previous referees will respond now if I contact them.
If I don’t apply at the end of this year that will be another year out in industry and I may not have another opportunity again. I’m feeling the melancholy and depression at the moment, Does anyone have any advice on how I can proceed?
