My PhD was in computational modeling 3D printing process using Abaqus finite element analysis. It took me 5.5 years to get the PhD and I published 4 first author papers from it. The issue is, I had put forward my desire to do experimental work during my PhD. But that did not materialize. Looking back, I do regret not choosing an experential topic. The true fact is I was not getting any good PhD positions. I liked this topic and started it. I do have an experimental background in my masters and undergrad research. But that's like 6 years ago.
After 3 years of starting, I had realized that I might get into issues securing job after PhD. But I did not want to leave my PhD halfway. Now, I am trying to get a experimental+simulations postdoc position but I am unable to get one (thanks to both my CV and covid). I know that I have screwed up chances for an experimental+simulations position.
But, do you have any suggestions on how I can approach a professor for a postdoc position with such a proposition in mind?
Another negative point on my resume. I am 31 years old.
