Job Description

The Exoplanet Group at DTU Space, Technical University of Denmark, invites applications for three-year postdoctoral positions in exoplanet science. Our group focuses on the discovery and characterization of small planets, from rocky worlds to super-Earths and sub-Neptunes. We combine observations, data analysis, modeling, and instrument development to understand the properties and diversity of these planets and the processes that shape their evolution.

Our research has two particularly active areas. In atmospheric characterization, we study the atmospheres of small exoplanets using observations from both space- and ground-based observatories, aiming to understand their composition, evolution, and retention. Much of our current research draws on the James Webb Space Telescope (JWST), for which our group has led several successful observing programs (GO 2420, GO 3730, and GO 7675), alongside our involvement in numerous international collaborations, including involvement in ESA's Ariel Mission (Buchhave co-PI).

In extreme-precision radial velocity (EPRV) research, we work toward detecting and measuring low-mass planets, including through the Second Earth Spectrograph (2ES; PI: Buchhave; www.2es.dk). 2ES is a next-generation spectrograph under development for the MPG/ESO 2.2-m Telescope at La Silla, Chile, designed to search for temperate Earth-mass planets around bright southern solar-type stars. The project spans instrumentation, data analysis, stellar activity, and the preparation for commissioning and early science.

Our aim is to recruit a researcher whose scientific interests and expertise complement the group's work. The successful candidate will be free to pursue the questions in exoplanet science that they find most compelling, whether these connect directly to our current projects or bring related perspectives and methods to the group.

We consider an open and cooperative research atmosphere to be extremely important. Group members take an interest in one another's science, exchange ideas, and explore opportunities to work together. We hope to welcome a colleague who enjoys participating in such an environment while developing their own independent research.

You will join Prof. Lars A. Buchhave and Assistant Prof. Alexander Rathcke, and the growing Exoplanet Group at DTU Space (www.exoplanets.dk), located in the greater Copenhagen area. The group has access to data from world-class observatories, including JWST, precision RV spectrographs, and ESO facilities, and collaborates widely with researchers abroad.

Responsibilities and qualifications

We expect the successful candidate to develop and carry out original, independent research that complements the group's scientific interests. The specific direction will be shaped by the candidate's own interests and expertise. Possible research topics include:

• Characterizing exoplanet atmospheres through transmission or emission spectroscopy, atmospheric retrievals and modeling, JWST data analysis, or studies of stellar contamination.

• Detecting and characterizing low-mass planets through precision radial velocities, including RV data analysis, stellar activity mitigation, spectroscopic pipeline development, or 2ES instrumentation.

• Pursuing other closely related observational, theoretical, or computational questions that complement the group's research on exoplanets.

We seek applicants with demonstrated research ability in exoplanet science or a closely related field. Observational, theoretical, computational, and instrumental backgrounds may all be relevant, and experience in both of our main research areas is not expected. We particularly value scientific initiative and strong analytical skills.

As a formal qualification, you must hold a PhD degree (or equivalent). In your application, we encourage you to describe the research directions you would like to pursue and how they could complement the group's scientific activities.

We offer

DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and terms of employment

The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. In addition, supplements can be negotiated in accordance with DTU’s salary structure for scientific staff: www.inside.dtu.dk/en/human-resources/during-employment/salary/salary-structures.

The period of employment is 3 years. The starting date is flexible but would ideally commence in Q3-Q4 of 2027.
