Significance of "En-route" Masters? I am a first year Ph.D. student in Optical Science & Engineering. I have a B.S. Physics (Honors). I started doing research in Jan. of 2009. I started the Ph.D. program in Jan. of 2011. Currently I am still doing research for the same Prof. I started with in 2009 (I plan to stay with his group). He is suggesting that I should NOT get my en-route M.S. in Optical Sci. & Engr. I have published 6 conference proceeding, an extended abstract, and I am currently writing my first journal paper and just submitted another abstract for a conference proceeding. His claim is that no one really considers your M.S. if it is the same as your Ph.D. I would select the non-thesis option M.S. which would require me to take 3 more courses (I have 6 courses left for my Ph.D.). He says that I could spend the time that I would spend for those courses earning my M.S. doing research. And the more publications and research experience I have the better chance I have of obtaining the job I want when I get out of school. My main concern is getting a job when I get out of school. I do not care whether I not I have my Masters (as long as I have my Ph.D.) I just want to do whatever will give me a better chance of getting a job. Any advice?
