I think looking at lab positions at other types of companies may open some doors.My best friend we went to college together both same education. His special interest is trees He got hired by a steel manufacturing plant took care of the waste water and gases a lot of his position involved testing for bacteria in the waste water.
I used to think that I had to look at actual big laboratories for lab jobs but factories, construction companies, lumber companies, schools, greenhouses, ect. have small laboratories. If I can get a job, I still might take the laser and photonics degree program as it sounds interesting.
