Seiji’s research focus on the formation and evolution of galaxies and black holes in the early universe. To link visible and dust-obscured sides of these fascinating systems, he developed an expertise in observational techniques combing the electromagnetic spectrum from optical to radio wavelengths. Seiji has been applying these techniques to his multiple Principal Investigator programs of JWST and ALMA, characterizing three fundamental aspects of the early galaxies such as their chemical enrichment, the assembly history of their stellar dust, gas, dark matter, and kinematics. Seiji has been playing key roles also in large JWST and ALMA programs in collaborations to search for the first emergence of stellar light, dust, blackholes, and stellar explosions in the universe and to investigate the primary formation and evolution mechanisms from the first galaxies in the first billion years after the Big Bang.
