Commission aims to highlight career options for postgraduate science students.
A new group aims to help graduate students to learn about their options for scientific and other careers, particularly outside of academia. Announced on 8 September, the Commission on Pathways through Graduate School and into Careers has been formed by the US Council of Graduate Schools and the Educational Testing Service. Patrick Osmer, chairman of the commission and vice-provost for graduate studies at the Ohio State University in Columbus, says that the group is polling students about their knowledge of career options, questioning those who have graduated about their career paths and asking employers in various sectors about their needs. The findings will be out in April 2012.

Undergraduate-focused colleges aren't known for research. But they are attractive to those with an interest in teaching.


On a sultry morning in early July, two undergraduates are hard at work in Alison Holliday's chemistry lab at Swarthmore College, a four-year liberal-arts institution on a pastoral campus a few kilometres outside Philadelphia, Pennsylvania. As part of Holliday's research into environmental contaminants, senior-year student Daniel Pak hunches over a syringe, desorbing pesticides. Travis Mattingly, a junior, tests for melamine, an illegal additive in pet foods and other products. During the ten-week summer break, research heats up in Holliday's lab.

Middlebury College in Vermont is one of many liberal-arts colleges hiring researchers who enjoy teaching.
The students and Holliday, an assistant professor in analytical chemistry, each spend about 40 hours a week in the lab over the summer. Like her colleagues at other liberal-arts colleges in the United States — institutions that focus on giving undergraduates a broad education in academic subjects — Holliday depends on the summer semester and her undergraduates to advance her research. Her teaching and other obligations at Swarthmore keep her from spending more than a few hours a week on research during the rest of the year. And Holliday needs her undergraduates as lab personnel because the college has no graduate students and few postdocs.
Holliday and her students are aiming to develop faster and more efficient ways of measuring levels of environmental contaminants, although it is unlikely that any of the work will lead to a paper this year. She isn't worried, even though her most recent article came out in 2009. The 'publish or perish' edict that typically drives faculty members at large universities isn't the rule at Swarthmore and other liberal-arts colleges. At such institutions in the United States and, increasingly, elsewhere (see 'Europe embraces the trend'), teaching has as large a role as research in tenure review, and Holliday loves teaching as much as being at the bench. Her outlook is tied to her students. “It would be very difficult to go back to a research university and not have that level of interaction,” she says.

Box 1: A Spreading model: Europe embraces the trend
Although mostly a US phenomenon, liberal-arts colleges have started to gain traction elsewhere — notably in the Netherlands. “Here, we are moving away from an egalitarian past to create programmes for talented, motivated students who were otherwise becoming invisible,” says Harm Hospers, dean of University College Maastricht, a liberal-arts institution that opened in 2001. This is one way in which the country has responded to calls for higher-education reform and new degree standards across Europe, as outlined in the Bologna Process agreement of 1999.
To date, five Dutch liberal-arts and sciences colleges — University College Maastricht, University College Utrecht, Amsterdam University College, Roosevelt Academy in Middelburg, and Leiden University College — have grown out of existing research institutions. These colleges increasingly focus on science, yet they often rely on their parent universities' infrastructure and research expertise to do so, says Marijk van der Wende, dean of Amsterdam University College.
In the Netherlands, positions for scientists can be based at the affiliated university or at the liberal-arts college itself. Core faculty positions at the liberal-arts colleges typically require PhDs, but focus almost exclusively on teaching — so research is pursued elsewhere. But university researchers can boost their careers and their chances of tenure by teaching at the colleges. They also gain access to top students interested in pursuing graduate studies.
Scientists at such institutions have much-sought-after autonomy, says Terence Kealey, vice-chancellor of the University of Buckingham, UK, an independent liberal-arts college. Kealey believes that if his institution is to ascend the university rankings, it must build up its research base. He hopes to double the number of science faculty members from 35 to 70 in the next few years, although the main focus will stay on teaching. Jacobs University Bremen in Germany, which opened in 2001, is another liberal-arts college with a science focus.
And Rotterdam University in the Netherlands and Freiburg University in Germany are creating their own liberal-arts programmes. Such institutions seem likely to see continued growth in several parts of Europe. Virginia Gewin

Demand for scientific posts at these colleges is on the rise, suggest figures from the US National Institutes of Health (NIH), which funds biomedical research at undergraduate institutions through its Academic Research Enhancement Award (R15). In 2000, the NIH reviewed 501 R15 applications. By 2010, that had increased by nearly 50% to 992, although the number of grants awarded has not risen apace (see 'Increased demand'). During the same period, the number of reviewed applications for R01 grants — the NIH's primary research award — rose by 27%. Fierce competition for the few academic slots at universities, and a legitimizing of liberal-arts colleges as research institutions, have contributed to the rise in demand for positions at undergraduate institutions, says Howard Garrison, public-affairs director of the Federation of American Societies for Experimental Biology in Bethesda, Maryland. “We are seeing highly trained researchers taking jobs at the types of institutions that a decade ago would not have been likely destinations,” he adds.

What's in it for an academic researcher who bypasses high-status, research-intensive universities for a tiny undergraduate college? A lot, say early-career scientists and veteran researchers at such institutions. They love doing actual bench research instead of being a de facto lab manager. They're relieved to be free of the panicked scramble for grants. And, like Holliday, they enjoy teaching and advising undergraduates.

A different world

But being a scientific researcher at a four-year liberal-arts college is not at all the leisurely, indolent experience that some might envisage, warns Amy Cheng Vollmer, a microbiologist who has worked at Swarthmore since 1989. “It's like comparing the winter Olympics to the summer Olympics,” says Vollmer, who frequently gives talks on career issues. “It's not easier; it's different.”
The teaching responsibilities are among the biggest differences. Specifics vary by institution, but junior faculty members typically teach two or three courses in the autumn semester and two in the spring, with a minimum of one lab section for at least one course. Along with teaching comes a raft of associated tasks: assembling a syllabus and selecting textbooks; developing lectures and lab sessions; and assigning exams, papers, lab reports and other classroom work. Although some of these tasks eventually become easier, others are perennially time-consuming. “I do all my own grading,” sighs Holliday.
Researchers also take on advisory obligations, including shepherding students through a thesis, counselling student organizations and managing honours and independent-study programmes. And the small size of the colleges means that they may have to share equipment with another institution or even build their own — equipment that, at a larger campus, would already be in place or easily purchased. Anne Goodsell, a physicist at Middlebury College in Vermont, had to build her own apparatus for her work on laser cooling of atoms.
Goodsell has no thoughts of returning to a research-oriented institution such as Harvard University in Cambridge, Massachusetts, where she was a graduate student and postdoc, despite the greater number of nearby colleagues at such universities, and the associated ease of collaboration. Other researchers, however, do find the relative isolation at small colleges hard. “There certainly is collaborative work here, but typically you're the only one who does what you do,” says Tiku Majumder, an atomic physicist at Williams College in Williamstown, Massachusetts. “I miss the opportunity for close collegial scientific exchanges every day.”

To beat the sense of isolation, Vollmer advises staying active in professional societies and attending as many conferences as possible. A resource for physicists in particular is the Anacapa Society, based at Amherst College in Massachusetts, which was created in 2003 in part to address that lack of connections.
Isolation isn't the only stumbling block. “The research rhythm is different,” says Majumder. “It can take years to publish. As measured by how many papers I've authored, no way could I compete with my colleagues at big universities.” With undergraduates, researchers can also expect a smaller and less experienced team, which can detract from the science itself. “I am the sole source of continuity in my lab,” says Holliday. “I am the sole problem-solver and troubleshooter-in-chief.” Scientists must also scale down their experiments to adapt to having less time in the lab. If a project doesn't work one summer, it must usually be abandoned, at least until the following summer. Experiments that require more than a couple of months are typically not possible. “You've got to come up with small projects that you can quickly ramp up,” cautions Vollmer. “You can't study the long-term effects of fire on a site. You can't study corn, because it has only one growing season a year.”
Still, a research career at a liberal-arts college has its assets. Financial support is a huge benefit — many US liberal-arts colleges offer a start-up package, salary and internal funding that allow researchers to dodge the constant struggle for grants that their colleagues at research universities undergo. Bridge funding helps with grant gaps. Many liberal-arts colleges also provide funds for lab equipment. And researchers don't have to support graduate students, postdocs or, usually, lab technicians. “I don't worry about money — basically ever,” says Nick Kaplinsky, a plant biologist at Swarthmore.
In the United States, several grant schemes are tailored to researchers at liberal-arts institutions. The NIH awards about 200 R15s each year; the maximum funding is US$300,000 over three years. The National Science Foundation (NSF) has the Research in Undergraduate Institutions (RUI) programme, which allows eligible researchers in the physical and biological sciences to apply for NSF grants. Applicants must submit impact statements explaining how the grant would affect their research, their department and their institution. “You can include information about the students you have working with you and the educational activities interwoven into the research project,” says Robert Scott Fisher, programme director at the NSF's division of astronomical sciences in Arlington, Virginia. “You have an extra chance to explain the impact of the award.”
The NSF also offers three- to five-year grants with no maximum through its Faculty Early Career Development Program for tenure-track faculty members who combine research with teaching. The Research Corporation for Science Advancement, based in Tucson, Arizona, offers two-year grants of up to about $75,000 to early-career scientific researchers at undergraduate institutions.
There is also, in general, a less furious battle for tenure than at many big universities. “We hire with the intent that the person will become a permanent part of the community,” says Cecilia Conrad, vice-president of academic affairs at Pomona College in Claremont, California. “We provide resources and advice so that the assistant professor will be successful in earning tenure.” Pomona offers faculty members a fully paid year's leave from teaching in their third year of employment, to let them focus on research. Still, Conrad says, Pomona's tenure process requires excellence in both research and teaching, as well as evidence of contributions to the community.
The teaching emphasis, in particular, can have a big impact. At Swarthmore, candidates for tenure must have letters of review from 25 students. “If you have an aptitude for teaching, and for performing, which in some ways teaching is about, then tenure is almost more of a sure thing,” says Kaplinsky, who recently earned tenure.
Ultimately, say researchers at liberal-arts colleges, the biggest payoff is helping students learn how to become scientists. “They're dry sponges — they're new, they're hungry to learn, and they're full of ideas,” says Bruce Kohorn, a biologist at Bowdoin College in Maine, who in 2001 left Duke University in Durham, North Carolina. “I love that.”

Military exercises 'good for endangered species'

Military exercises are boosting biodiversity, according to a study of land used for US training manoeuvres in Germany. Such land has more endangered species than nearby national parks.
The land is uncultivated, but also churned up by tank tracks and explosions. This creates habitat both for species that prefer pristine lands and those that require disturbed ground, explains ecologist Steven Warren of Colorado State University in Fort Collins.
Military land can host more species than agricultural land, Warren told a meeting of the Ecological Society of America in Montreal. What's more, its biodiversity can also exceed that of natural parks, where species that need disturbance cannot get a foothold.
Warren and his colleague Reiner Büttner of the Institute of Botany and Landscape Ecology in Hemhofen, Germany, surveyed two US military bases at Grafenwoehr and Hohenfels in the southern state of Bavaria. Although the bases represent less than 1% of the state's area, they contain 22% of its endangered species, Warren told the meeting. The national parks cover a similar area but host fewer endangered plants and animals, Warren says.

Nature's army

"Some people are very anti-military," Warren says. "They assume that there's nothing the military can do that will be beneficial, particularly with relation to ecology." Warren, who doesn't work for the army, used to assume the same himself. "Twenty years ago I looked at military activities as an ecologist and thought 'they need me'. But I guess that's not really so."
Warren and Büttner studied several species to try and understand the benefits of military ground. One, the natterjack toad, breeds in water-filled ruts created by tank tracks, they found.
The tendency when setting aside a nature reserve is to prevent disturbances such as periodic flooding, says Warren. But this can inadvertently remove some habitats.
"[Tanks] replace to some degree the processes that have been stopped," Warren says. The same goes for fires caused by bombing. "We've trained generations of people that fire is bad," he says, "but in fact it's crucial for ecosystems."

Trial by fire

The number of species on former Soviet training camps around Berlin has dropped since the fall of the Iron Curtain, Warren says, supporting the idea that military activity is good for biodiversity.

"But some military chiefs worry that endangered species may begin to obstruct their exercises." The US Marine Corps has previously complained that the US Endangered Species Act threatens to turn its Camp Pendleton beach in San Diego County, California - home to 18 threatened species - into a nature reserve rather than a training facility.
Warren hopes that conservationists could learn from the military, and provide disturbances to help endangered species. One trial project at Tennenlohe, near Nuremberg in Germany, involves cutting up land using an agricultural tool called a ripper in a bid to mimic tank tracks.
