Sasselov is a prominent astrophysicist and planetary scientist known for pioneering contributions to exoplanet detection, stellar variability, and studies of planet formation. He has played leading roles in observational programs, instrument development, and theoretical modeling that connect observations from space telescopes and ground-based observatories to models of planetary atmospheres and interiors. His work bridges collaborations among institutions and missions that include major observatories, research centers, and international consortia.
Sasselov was raised in a family environment that encouraged scientific inquiry and pursued formal education in physics and astronomy at leading universities. He completed undergraduate and graduate training that combined coursework and research under advisors affiliated with institutions such as Harvard University, California Institute of Technology, University of Cambridge, Massachusetts Institute of Technology and research groups connected to observatories like Mount Wilson Observatory and Palomar Observatory. His doctoral research engaged with stellar photometry, time-series analysis, and instrumentation development that later underpinned work with facilities such as Hubble Space Telescope, Kepler (spacecraft), and Transiting Exoplanet Survey Satellite.
Sasselov’s academic appointments have included professorships and directorships at major research universities and observatories, collaborating with teams at Harvard-Smithsonian Center for Astrophysics, Harvard University, Smithsonian Institution, Max Planck Institute for Astronomy, and national laboratories. He has been involved in mission science teams and instrument consortia for space missions and ground-based surveys, working with organizations such as NASA, European Space Agency, Space Telescope Science Institute, and national science foundations. His research groups have combined observations from facilities including Subaru Telescope, Keck Observatory, Very Large Telescope, and radio arrays associated with institutions like National Radio Astronomy Observatory.
Sasselov has supervised graduate students and postdoctoral fellows who later obtained appointments at institutions including Princeton University, University of California, Berkeley, University of Cambridge, Stanford University, and University of Chicago. He has participated in international workshops and conferences organized by societies such as the American Astronomical Society, Royal Astronomical Society, International Astronomical Union, and editorial boards for journals published by Nature Publishing Group, American Physical Society, and Institute of Physics.
Sasselov’s scientific contributions span observational discovery techniques, transit photometry methodology, and theoretical interpretation of planetary atmospheres and interiors. He played central roles in advancing transit detection strategies used by missions like Kepler (spacecraft), CoRoT (satellite), and COROT, and helped to develop analysis pipelines that improved signal extraction in the presence of stellar variability measured by instruments aboard Hubble Space Telescope and Spitzer Space Telescope. His work has linked stellar activity and pulsation studies from observatories such as Mount Wilson Observatory and Las Campanas Observatory to exoplanet detection limits.
On planetary atmospheres, Sasselov contributed to early interpretations of transmission spectroscopy data obtained with facilities including Hubble Space Telescope, Spitzer Space Telescope, and James Webb Space Telescope planning teams, addressing issues such as cloud opacities, molecular signatures, and atmospheric escape processes related to observations from High Accuracy Radial velocity Planet Searcher and HARPS. He has engaged with theoretical models of planet formation tied to protoplanetary disk studies informed by observations from Atacama Large Millimeter/submillimeter Array and numerical simulations developed in collaboration with research groups at Princeton University and Caltech.
Sasselov also contributed to public-facing initiatives and citizen science projects that connected surveys like Wide-field Infrared Survey Explorer and Sloan Digital Sky Survey with outreach platforms and university-led programs, fostering interdisciplinary links among observational campaigns, laboratory spectroscopy efforts at institutions like Max Planck Institute for Astronomy, and atmospheric retrieval frameworks used by groups at MIT and University College London.
Sasselov has received recognition from national academies and professional societies for his contributions to astronomy and planetary science. Honors include fellowships and awards associated with organizations such as the American Academy of Arts and Sciences, Royal Society, American Astronomical Society, and national research councils. He has been invited to deliver named lectures sponsored by institutions including Harvard University, Smithsonian Institution, and international symposia organized by the International Astronomical Union.
His leadership in mission science and instrument development has been acknowledged by awards from agencies like NASA and prize committees at universities and research institutes tied to the European Southern Observatory and national science foundations.
