| Outline of Research at the Start |
The research will be conducted in several phases, which will be overlapping in time. Initially the primary tasks will be related to data processing and analysis, then as promising new candidates are identified they will be scheduled for follow-up observations. The data from these follow-up observations will then be analyzed, which then leads to the final phase of publishing the results.

| Outline of Final Research Achievements |
Since the Kepler mission, a new era of planet discovery has begun, which involves large quantities of data from space telescopes. By analyzing data from the TESS mission we are expanding the planet search to the whole sky, enabling the discovery of many new planets that can be explored in more detail. In particular, the unprecedented scale and precision of TESS provides many excellent targets for further study using large ground-based telescopes as well as the recently launched JWST. By enabling such detailed studies, open questions about planet formation, migration, and evolution can ultimately be addressed. However, to achieve this we need to process large quantities of data, which presents both technical and human challenges. By building automated pipelines that run on high performance machines, the scale of the human challenges can be brought to a reasonable size. For the best planet candidates we discover, the computation of robust parameter estimates can also be done efficiently.

| Academic Significance and Societal Importance of the Research Achievements |
Our understanding of how planets form is undergoing a revolution, allowing us to better understand our home planet and solar system. Furthermore, the discovery of biosignatures in the atmospheres of other planets has the potential to change our understanding of humanity in a universal context.
