After 22 years at Duke, the Bernhardt Lab is moving to Cornell University in Fall 2026 — read the announcement

Join the Lab

Opportunities for research in the lab

Before anything else: the lab's expectations of itself are written down. The Lab Contract — Code of Conduct covers goals, expectations, funding, intellectual property, field safety, and conflict resolution, and every current and former lab member has shaped it. New members read the whole document; it's linked here and at the bottom of this page.

What the lab has agreed to, in brief

"Our collective goal is to help every member of the lab to grow intellectually, to produce excellent scientific insights and to achieve their next desired career goal." Three tenets follow from that goal, taken directly from the lab contract:

Ways in

How people typically join

Work-Study, Volunteers & Assistantships

We're always glad to have help in the lab and field. Email lab manager Lauren Krohmer with the kind of work that interests you — she'll help match you to a project (see the Research page for current directions).

Summer Field Technicians

We typically hire summer research assistants for field and lab work. Watch this page and the Ecolog listserv, a good general resource for ecology jobs.

Independent Research

Interested in an honors thesis or independent-study research? Send Emily a detailed description of the research experience you're hoping to gain and why the lab is the right fit for those goals.

An open letter from Emily

This section is Emily's, written in her own voice — kept as she wrote it.

Thanks for your interest in my lab. Here is some information to help you with the whether, the where, and the how of choosing and applying to graduate school.

Maybe the best information of all is this article written by 15 lab PhD and postdoc alumni: "At the interfaces of the hydrologic sciences: Connecting water, elements, ecosystems, and people through the major contributions of Dr. Emily Bernhardt" (Helton et al., Journal of Hydrology, 2023).

First, have you thought this through?

Are you really ready to begin the 5–6 year process of earning a PhD? As a graduate student you can look forward to nearly nonstop (some might say relentless) intellectual stimulation, and you will have opportunities to work with really smart people in very interesting places. It's important to be aware that these benefits do not come cheap — you won't get rich in graduate school, and the job market for new PhDs is tough. So you have to love the process.

Second, is my lab the right place for your dissertation research?

I am always looking for bright, creative, motivated, and collaborative students with a keen interest in biogeochemistry to join my group. You can read about our current research projects, but our lab is willing and able to expand into new territory if the questions are compelling. To determine if you're a good fit for the lab, I encourage you to consider the following:

  • Are you willing to spend much of the next five years of your life either collecting field samples or performing analytical chemistry?
  • Do you desire nearly limitless opportunities to discuss the cycling of N, P, C, [insert element of choice here] with similarly minded folks?
  • Do you have a burning desire to understand how human activities are changing the sources and fates of biogeochemical elements?
  • Can you read at least three publications from our publications page at one sitting and find yourself more awake than when you started?

If you answer yes to at least three of the questions above, you may very well be a good fit within our lab. To help me make this assessment, please send me: 1) a detailed statement of why you want to attend graduate school and why my lab seems to be a good fit for you; 2) a description of your previous research experience; and 3) the names and institutions of the people who will provide your letters of recommendation.

As you're comparing potential graduate mentors, ask them about their mentoring philosophy. Here's mine, in brief. It is an honor and a great responsibility to have a talented student choose you as a graduate mentor. My job as a mentor is to help my students find their research passions, focus their enthusiasms productively, and ultimately help them fulfill their individual career goals. In return, I expect my students to teach me new things and to inspire me to ask new questions. I do not like to bring students into PhD research on funded projects as research assistants, because I believe it is critically important that a student choose their own questions and forge their own research trajectory. I prefer to help find the funds and the intellectual networks that can help students pursue the questions that inspire them. My lab group is a team of like-minded scientists who both push and help one another to do the best possible research, and I expect all members of my lab group to both offer and accept constructive criticism and assistance.

See Cornell's graduate admissions pages for current application deadlines, program affiliations, and requirements. Our program invites highly ranked candidates — meaning plenty of research experience, strong academic training, and a good fit with a potential advisor — to interview in person in early spring. Admissions decisions are made by a committee of graduate faculty.
