In a previous post I cited that only a quarter to a fifth of recent PhD graduates will end up in tenure-track faculty positions.1 This is in spite of the fact that a large percentage of doctoral students and postdocs start their programs and fellowships with the intention of becoming faculty. 2 If this is the case, why are there not more PhDs becoming professors?
One of the main contributing factors is that there are not enough faculty positions available in the US to keep up with the growing number of PhDs granted every year. Tenure-track faculty positions have remained fairly stable since 1991 while PhDs earned have increased 55% over the same period.3,4 To put this in perspective, there were 168,000 full-time faculty in 2006 and 41,000 science and engineering doctorates awarded the following year alone (ibid). This trend has led to fewer PhDs employed in academia (down to 45% from 55% over 1973-2006) and of those in academia, a greater proportion are now found in postdoctoral or non-tenured positions.5,6
This mismatch is the result of an inherently problematic training system in which new scientists are continually churned out but then left to flounder somewhere in the middle because positions at the top are few-and-far between, owing to a notoriously slow turnover rate in academia. Making matters worse, a spate of hiring freezes instituted during the recent economic recession led to even fewer academic job prospects.7 Even the stimulus package of 2009, which pumped 21.5 billion into science and engineering research, was not expected to alleviate this problem.8 PhDs are often rightly dismayed when unable to secure a job in the profession for which they have been trained, prompting many to ask "Are We Training Too Many Scientists?"9
The difficult job market does not garner all of the blame as aspects of faculty life can be equally discouraging to fresh graduates, as well. According to a 1999 survey, PhD candidates reported being concerned “about the problematic nature of the tenure process, onerous workload expectations, difficulty of obtaining research funding, and low salaries.”10 In addition, the average age of first obtaining a faculty position in the biomedical sciences has risen to 38, which means more time spent in low-paying postdoctoral fellowships11- not an appealing prospect for many young professionals who have already spent four years in college and an average 7.2 years in graduate school.12 By the end, a third of doctoral students across all disciplines reported decreased interest in faculty careers during graduate school.13
Beyond job market and faculty life concerns, yet others are steered away due to shifting career and life interests. In the journey to a PhD, some find scientific research to be less fulfilling than expected or discover new passions along the way. Former neuroscientist Laura Malisheski had her career epiphany during a postdoc: “I had been spending so much of my energy developing skills that I didn’t enjoy that I was forced to suppress my natural abilities . . . Finally, I had learned to appreciate the skills that truly motivated and energized me.” 14 Laura left the bench and found success as a career counselor for other PhDs. Not an isolated case, PhDs are now flourishing in many careers in industry, education, communications, consulting, patent law, policy, and the list goes on.
Although not its original intention, the PhD has evolved into a bridge to many career paths and academia has ironically become the “alternative”. As a solution to this "problem" is not in plain sight, the philosophy that a PhD is narrowly defined as training solely to be an academic scientist is outdated and needs to revisited.
