Data Science Group

Our Mission

The Data Science (DS) department supports all MPIA members to carry out novel, cutting-edge research and to establish MPIA as a world-wide leader in astronomical data science.

The data science group supports researchers across all MPIA departments. We focus our activities in four primary areas:

Foundational Skills: We help researchers strengthen their data management, analysis, and coding skills and build a solid foundation in modern software engineering and data practices. Our activities include running hands-on workshops, curating educational resources, and providing personalized support for learning and development. Join our in-person workshops (see newsletter bellow for dates and topics), come to office hours (see details below), or make an appointment to take advantage of these opportunities.

Innovative Solutions: We foster an environment where researchers can explore and develop solutions to scientific and technical challenges. Through collaboration, brainstorming, and consultation, we support the creation of new methods, tools, and workflows that advance astronomical research. Make an appointment to discuss your ideas with us.

External Presence: We connect with peers, institutions, and industry to share knowledge and shape emerging technologies. By building strong collaborations and engaging internationally, we help accelerate scientific discovery and amplify MPIA’s presence in the broader data science community. Please reach out via email if you’d like to discuss collaboration opportunities.

Career Development: We support researchers in planning and advancing their careers, both within and beyond academia. Our efforts include discussions about career paths, CV and résumé reviews, guidance on skill development, and networking opportunities that foster professional growth. We offer one-on-one sessions that can be reserved here (Iva) or here (Morgan) to discuss your specific goals.

External inquiries:

Please contact the relevant group member directly by email. We are unable to respond to marketing requests or unsolicited job applications that fall outside the student opportunities listed below.

Research & Projects

We are involved in several international astronomy projects as researchers and in functional roles. Our areas of interest include:

Machine learning and probabilistic inference for astronomical data
Large-scale data processing and distributed computing
Software engineering, data pipelines, and reproducible research practices
Statistical modeling and uncertainty quantification
Cross-calibration and integration of heterogeneous survey data
Visualization and interactive analysis of complex datasets
Development of public data services, APIs, and open-source tools

Current projects:

Euclid: an ESA mission that will map the geometry of the Universe to understand dark energy and the evolution of cosmic structure. We are involved in studies of galaxy evolution.
Roman: a NASA mission, planned to launch in 2026, that will conduct wide-field infrared surveys to study dark energy, exoplanets, and the structure of the Universe. We are involved with the High Latitude Wide Area Spectroscopic Survey.
JWST: We are involved in several surveys that use the spectroscopic capabilities of JWST to explore galaxy evolution and cosmology.
LSST: will image the entire southern sky repeatedly to study transient phenomena, map the Milky Way, and probe dark matter and dark energy.
Gaia: a mission charting a precise three-dimensional map of over a billion stars to reveal the structure, dynamics, and evolution of the Milky Way. We are involved in deriving the physical properties of objects observed with Gaia.
Gaia Unlimited: a project to characterize the selection function of the Gaia survey
Pristine: a program to search for the most metal-poor stars in the Galaxy
Phat/Phast/Phatter: Panchromatic Hubble Andromeda Treasury and Triangulum Extended Region – UV-optical-NIR photometry for >200 million stars in M31, M33

Group Members

In addition to the long-term staff members (left column), the following are also members of the group:

Dr. Raphael Hviding – Postdoctoral Resarcher – AGN and galaxy evolution
Dr. Aarya Patil – LSST Discovery Alliance Catalyst Postdoctoral Fellow – Milky Way formation and evolution
Mr. Yang Chen - MSc Student - Galaxy evolution

Opportunities

We welcome visitors who work at the intersection of astronomy and data science including data analysis, software development, and methodological innovation. Please reach out if you would like to give a talk, meet with the group or do a working visits. Visitors must be self-funded at this time. Please email us to inquire about opportunities. Our group meetings are open to all: please join us on Mondays at 13:00 in the 3rd floor Beschprechungszimmer at MPIA.

We can supervise students at the University of Heidelberg for BSc and MSc thesis projects. A list of example projects is available here and we are open to discussing other ideas. We can also supervise external students (those not enrolled at the University of Heidelberg) if the project is part of their academic curriculum and carries credit at their home institution. Successful candidates for our group have strong programming skills. Previous research experience is a plus. We review applications submitted through this form four times a year. Please specify if there is a particular project you are interested in working on in your application.

We support applications through external funding programs such as Fulbright, DAAD, Erasmus, and others for projects related to data science, software engineering, and the missions or collaborations we are involved in. Please reach out at least six weeks before the application deadline to discuss potential project ideas.

A full description of pre-doctoral oportunities at MPIA is available here. We currently do not have any open positions for PhD students, postdocs or staff members.
