Natural Science Professor Job Description

A Natural Science Professor operates in two parallel professional tracks simultaneously: the classroom and the research lab. At a research university, neither track is optional — the expectation is that both are productive, funded, and advancing on a schedule measured in semesters and grant cycles. At a liberal arts college or community college, teaching absorbs far more of the week, but the intellectual foundation is the same: deep disciplinary expertise applied to the instruction of students and, to varying degrees, the generation of new knowledge.

The teaching side of the role is more varied than the title suggests. A biology professor might teach introductory cell biology to 200 non-majors in a lecture hall one semester, lead a seminar of eight senior thesis students the next, and supervise a graduate student teaching a lab section she designed. Course preparation at the professor level isn't writing new lecture slides — it's staying current with a field that publishes thousands of papers per year and deciding which developments are pedagogically important, then building assessments that actually measure whether students have internalized them.

The research side demands a different kind of sustained effort. Running a productive laboratory means writing grant proposals before the current grant expires, managing a team of graduate students and postdocs at different stages of their projects, reviewing data, revising manuscripts, and responding to peer reviewers — all while teaching. Grant writing is not a background task. A competitive NSF or NIH proposal is weeks of focused work, and the acceptance rates at major agencies have ranged from 15–25% in recent cycles, which means most proposals get rejected and must be revised and resubmitted.

Laboratory safety is a non-trivial part of the job that gets underemphasized in academic portrayals of professorship. A principal investigator is the responsible party for everything that happens in their lab space — chemical storage, radiation use authorization, biosafety containment levels, pressure vessel certification, fume hood inspection logs. OSHA and EPA regulations apply on campus the same as in industry, and institutional environmental health and safety offices conduct regular audits. Faculty who treat safety as someone else's administrative burden create real liability for themselves and their institution.

Service — committee work, peer review, grant panel participation, professional society leadership — accumulates quietly and can consume 15–20% of a senior professor's time. Knowing which service commitments build genuine professional standing versus which are low-value time sinks is a skill developed over years of watching senior colleagues navigate the same decisions.

Education:

• Ph.D. in biology, chemistry, physics, earth science, environmental science, or closely related discipline (required for tenure-track positions)
• One or more postdoctoral appointments (2–5 years total, strongly expected by R1 and most R2 hiring committees)
• Master's degree sufficient for some community college and instructor positions

Research credentials that hiring committees evaluate:

• Publication record: peer-reviewed journal articles, with attention to journal impact, author position, and citation counts
• Grant history: PI or co-PI on external funding from NSF, NIH, DOE, USDA, or equivalent private foundations
• Evidence of an independent research program distinct from the dissertation or postdoc advisor's program
• Invited talks at national conferences and evidence of a professional network in the subdiscipline

Teaching preparation:

• Graduate teaching assistant experience (virtually universal among candidates)
• Course design experience beyond TAing — co-instructing or sole instructorship during postdoc or as a visiting faculty member
• Evidence of inclusive pedagogy training is increasingly expected, particularly at liberal arts institutions

Technical skills that vary by discipline:

• Biology: molecular techniques (PCR, CRISPR, flow cytometry), microscopy, bioinformatics pipelines
• Chemistry: NMR spectroscopy, mass spectrometry, synthetic methods relevant to subdiscipline
• Physics: computational modeling, instrumentation design, data acquisition systems
• Earth/environmental science: GIS, remote sensing, field sampling protocols, geochemical analysis

Institutional compliance:

• Lab safety officer designation training (institution-specific)
• Responsible conduct of research (RCR) certification
• IRB and IACUC protocols for human subjects or animal research
• ITAR/export control awareness for labs with international collaborators or controlled materials

The academic job market for natural science faculty has been structurally tight for more than a decade, and that structural constraint has not resolved. The number of Ph.D.s awarded in the natural sciences each year substantially exceeds the number of tenure-track positions opening up, creating a long postdoctoral holding pattern for many candidates and an extremely competitive application environment for those who do enter the market.

That said, the picture varies considerably by field, institution type, and what counts as success.

Field-by-field variation: Environmental and climate science positions have seen sustained growth driven by federal research priorities and institutional commitments to sustainability research. Biomedical sciences depend heavily on NIH funding trends, which have faced political and budget pressures that affect both the number of faculty hired and the sustainability of existing programs. Physics and chemistry hiring tracks with federal R&D investment cycles — materials science and quantum computing subfields are seeing more activity than traditional subdisciplines.

Institution type: The intense competition is concentrated at research universities. Primarily undergraduate institutions and community colleges hire regularly, often struggle to attract qualified candidates who are also strong teachers, and offer more stable long-term positions — just with lighter research infrastructure. For candidates who find teaching genuinely more satisfying than grant writing and publication pressure, this tier deserves serious consideration rather than being treated as a fallback.

Federal investment signals: The CHIPS and Science Act, Inflation Reduction Act funding for climate research, and continued NIH budget activity have maintained federal research expenditure at levels that support faculty positions in aligned fields. Budget uncertainty in 2025–2026 has created some caution at institutions that rely heavily on indirect cost recovery, but the underlying demand for trained scientists in teaching and research roles has not contracted.

Non-academic career integration: Faculty careers increasingly intersect with industry, national labs, and government agencies through consulting, collaborative grants, and industry-sponsored research. Professors who maintain connections to applied work — whether through DOE national lab partnerships, biotech collaboration, or environmental consulting — tend to have more resilient research funding portfolios and better-placed students.

For a candidate entering a tenure-track position today with a well-funded research program, the career is financially stable, intellectually rewarding, and offers genuine autonomy. The path to that position, however, requires sustained output and competitive positioning over a multi-year postdoctoral period that not all candidates find sustainable.

Dear Search Committee,

I am applying for the tenure-track Assistant Professor position in Environmental Chemistry at [University]. My research program focuses on the fate and transformation of per- and polyfluoroalkyl substances (PFAS) in aquatic systems, and I believe the combination of your department's water quality research cluster and the undergraduate research opportunities at [University] aligns closely with how I want to build the next phase of my work.

During my postdoctoral appointment at [Institution], I developed and published a novel liquid chromatography-mass spectrometry method for detecting precursor PFAS compounds in stormwater at concentrations an order of magnitude below previous detection limits. That work resulted in two first-author publications in Environmental Science & Technology and a co-authored EPA-funded report that has been cited in three state-level regulatory proceedings. I am currently preparing a proposal to NSF's Environmental Chemical Sciences program based on that methodology, targeting a submission date of October 2026.

On the teaching side, I taught a standalone section of Analytical Chemistry I during my second postdoctoral year, taking over from a faculty member on leave. I redesigned the laboratory component to incorporate real stormwater samples collected by students at local outfalls — an approach that improved engagement measurably and resulted in two undergraduates co-authoring a conference poster. I have attached my teaching statement, which describes that course in detail and outlines how I would approach the department's Environmental Analysis course.

I would welcome the opportunity to speak with the committee about how my research and teaching fit your current needs.

Sincerely, [Your Name]
