Dr. Ueta is an associate professor and an observational astronomer/astrophysicist in the Department of Physics and Astronomy. While there are many specific research projects at any given time, his research interests revolve around stellar mass loss process - one of the remaining missing pieces in our understanding of stellar evolution - because
More broadly, Dr. Ueta's research interests are encompassed by the following topics:
(1) stellar evolution: particularly looking into the late stages of evolution from the Red Giant to the Planetary Nebula phases involving mass loss processes
(2) astropaleontology: investigation into the history of stellar mass loss by observing the circumstellar gas/dust distribution
(3) astromineralogy: study of the composition and formation of circumstellar and interstellar matter, especially dust grains
(4) radiative transfer in dusty media
(5) observations of circumstellar phenomena using optical, infrared, sub-mm, and radio
(6) interactions between stellar winds and the interstellar medium
Dr. Ueta has used various space-based and ground-based telescopes/observatories around the world in the wavlength ranges from UV to optical to IR to Radio.
There are always some research opportunities for students. If you are interested in any of these topics and related ideas, please contact me!

Far-infrared emission from OH+ molecules was detected for the first time from planetary nebulae based on observations made as part of the Herschel Planetary Nebula Survey (HerPlaNS, Dr. Ueta is the PI of this project) and other programs.
A bow-shock like "wake" due to intersctions between stellar winds and the interstellar medium around the low-mass asymptotic giant branch star R Hya was discovered in the far-IR emission for the first time around this type of star.
