So I'd like to listen to some advice of what anyone might have of my situation before I really make a decision of what path I should pursue. It basically pertains to whether I should just seek avenues elsewhere other than research or continue on building with what little I have after failing to obtain any admits during my last admission try.
I just finished my bachelor's degree with a 4.57/5.0 GPA in Materials Engineering in a university in Singapore with the biggest Materials department in the country. I tried applying for PhD in 8 universities in US last year and not only I didn't get admitted into any, I was rejected pretty early in the decision stage. I have done a little less than three years of undergraduate research across two fields with mostly the same research group and professor, however I don't have any papers published because my Professor doesn't tend to do that easily and I personally didn't push for it either. I have a GRE score of 1360 (790Q) taken last year. I also participated in an exchange program to Iowa State University for a semester during my third year and got a 4.0/4.0 semester GPA for core courses if that changes anything.
So right now I'm not really sure what I should do. Normally it's simple to just say to try again, but with my rejects coming so quickly last time, I don't believe I have sufficient credentials to get admits that I want. I do have to admit that my applications was not the best prepared with my decision to do so coming in the only last two or three months, but I feel that my undergraduate university and/or department is just not so recognized in terms of PhD applications. Case in point, other students in the same department who had better or similar results to mine barely edged out in applications with most of them getting only one admit out of all of the universities they applied for. One that I know well, had better academic results, did more research than me, had a 1500 GRE score, and had two or three papers published still had zero admits out of nine last admission cycle. Furthermore, I might have made some missteps in only doing most of my research under one particular professor during my undergraduate study. While I still think that my professor is good to perform research under and learn from, I don't think she spends much effort in providing support for her students in their PhD applications. Of course, this complicates my admissions too since I barely have any strong references from professors that really knows my work.
Naturally, I would ask myself what I could improve on if I were to try again this year, and the only significant thing is the statement of purpose which I'm not sure is significant enough to warrant a retry. My last statement of purpose was pretty pedestrian I would say, but this time I could add in my experiences while working on my thesis which was still ongoing last year. Basically I had a thesis project that had a lot of complications and measurements that produced remarkable, but unexplainable results that had never been reported before. I think my professor and my mentors pretty much gave up hope in the beginning on the project with such confounding measurements. But since I couldn't really change my project and thought it was still worth working on, I labored on and resisted any calls to just write it off with some hand-waving explanations. In about two months or so, I finally came out with a plausible theory that could explain the results, but to my dismay, all my work seems to been for naught as no one could really help in proving (and disproving) it. The ones that were doubtful (it certainly comes with the profession and I don't blame them for it at all) couldn't point out why I was wrong, and the ones that were somewhat supportive couldn't help me either with the lack of equipment and expertise. Needless to say, I was pretty depressed for a while with that and my admit failures. It was only during my thesis presentation where my examiner agreed that my university was simply lacking the skills and resources to perform such research work. While I felt somewhat relieved to finally have someone telling me it's hardly my fault, it doesn't really help me on my chances on my future admits either. Nevertheless, that experience pretty much cemented my decision to not pursue a PhD degree in my undergraduate university even though I had offers for it.
So I'm in a situation that I have little to show to get the admits that I want, yet I'm convinced that it's not worth it to simply enter any university to undergo a PhD degree because the degree alone would be hardly worth the time and effort. There's no research assistant positions that I can apply for at the department so working further on the same research without a PhD is pretty much not an option, plus I'm not sure going back to the same research group I've been working for around three years now is a good idea.
Now I'm at a fork and I'm unsure what to do, and I certainly lack advice from people who has gone through similar problems before. From what I can see, I can...
a. Find a job in another field and complete the bond, put off PhD for now, but risk getting even harder to come back this way in the future.
b. Find a job in another research field whatever it takes, to prop up the credentials and qualifications to retry in the future.
c. Just try for admits again this year, there's nothing to lose aside from some time and money, but I'm not sure the things I have are sufficient.
I can't really make up my mind now. But I heard people giving advice before, saying that if you can picture yourself doing something else other than PhD, than you shouldn't apply for it... is that the advice I should just follow? I'd appreciate any opinions on this.
Either way, thanks for reading this far.
