Kiyoaki Doi

Dr. Kiyoaki Doi is a Research Fellow at the Max Planck Institute for Astronomy in Heidelberg, Germany, where he works in the Planet and Star Formation Department as part of the Planet Formation and Exoplanets group. He joined the institute on October 1, 2024, and conducts cutting-edge research on planet formation through observations of protoplanetary disks using advanced telescopes like ALMA.

His primary research interests include:

• Planet Formation
• Exoplanets
• Protoplanetary Disks
• Astronomy
• Astrophysics

Dr. Doi's recent work has gained significant recognition in the astronomical community, highlighted by a press release from the Max Planck Institute for Astronomy on December 13, 2024, titled 'ALMA Reveals the Birthplace of a Planetary System.' In August 2025, he successfully secured two proposals as Principal Investigator for ALMA Cycle 12, demonstrating the scientific merit and competitiveness of his research projects.

His observational approach focuses on using millimeter and submillimeter wavelength astronomy to study the structure and composition of protoplanetary disks, providing critical insights into the physical processes that lead to planet formation. This research bridges theoretical models with empirical data to advance our understanding of how planetary systems, including potentially habitable ones, form and evolve.
