Computing Community Consortium Blog

The goal of the Computing Community Consortium (CCC) is to catalyze the computing research community to debate longer range, more audacious research challenges; to build consensus around research visions; to evolve the most promising visions toward clearly defined initiatives; and to work with the funding organizations to move challenges and visions toward funding initiatives. The purpose of this blog is to provide a more immediate, online mechanism for dissemination of visioning concepts and community discussion/debate about them.


CS PostDoc Numbers Surge Again, Recent Data Show — We Need Your Input!

Computer Science PostDocs... a CRA facilitated conversationThe Computing Research Association recently published the results of its annual Taulbee Survey, and the numbers of PostDocs rose to record levels, continuing a trend that we have witnessed for more than a decade — and bringing new meaning to the CRA’s PostDoc white paper effort.

Background

As we have blogged here before, CRA — the umbrella organization of the CCC — initiated an effort last fall to engage the community in a conversation about PostDocs, at a time when a growing number of new CS PhDs appeared to be going that route. A committee commissioned by CRA prepared a white paper reporting the statistics associated with academic and industry hiring, with the aim of providing a starting point for further discussion throughout the community. The white paper was posted online on Feb. 2 — http://cra.org/postdocs — and we have received some comments on the companion web forum.

New Survey Data

Based on this year’s Taulbee Survey data, the three-year rolling average for the number of new PhDs pursuing PostDocs rose from 159 in 2009 to 218 in 2010 — an increase of 37% in just one year. That’s on top of a tripling in the number of PostDocs observed during the 12-year period from 1998 through 2009, as reported in the white paper, suggesting that the trend toward PostDocs is not only continuing but perhaps also accelerating.  Meanwhile, the number of new PhDs who pursued tenure-track faculty appointments declined yet again, from 151 in 2009 to 137 in 2010, or 9% (three-year rolling averages). (The numbers of new PhDs pursuing other positions, including teaching and research appointments in academia, positions in industry, etc., remained essentially flat.)

Here’s a graph showing the hiring of new computer science PhDs from U.S. and Canadian universities from 1998 through 2010 (three-year rolling averages):

We Need Your Input

What do you think about these trends — and the implications for PostDocs, graduate students, faculty, universities, companies, and the field as a whole? Please discuss the white paper with your colleagues within your departments and labs — and post your views about this trend and PostDocs generally on the companion web forum: http://cra.org/postdocs. Some things to consider:

  • Should funders increase or decrease the number of PostDocs in response to the economy, or, more explicitly, in response to academic and industrial hiring trends?
  • Does an increase in funding of PostDocs come at the expense of funding for graduate students? If so, at what point does the growth in PostDoc positions begin to threaten the pipeline of next-generation researchers?
  • Is the PostDoc the most effective way to encourage interdisciplinary interactions?
  • Are there reasons to maintain a PostDoc pipeline in one computing subfield at a higher level than in another?
  • To what degree is a PostDoc experience helpful for a researcher who will take a non-academic position?
  • Is there a gender difference in terms of the impact on PostDocs?
  • To what extent should the computer science community be engaged in setting guidelines for the balance between PostDocs and students, if the total amount of funding is roughly constant?

Your input is immensely valuable, as the committee will soon compile and articulate the consensus of the community, if any, on this issue.
