Research

I am involved both in instrumentation and pure research projects, with a significant overlap between the two.

Together with my colleague Don Hall, I have developed the HAWAII series of infrared detector arrays, with our industrial partner Teledyne (formerly Rockwell). These detectors were instrumental in bringing infrared astronomy to a level of maturity similar to optical astronomy. We are currently concluding the NSF-funded development of the HAWAII-4RG-15 detector arrays, and are now concentrating on avalanche photodiode devices.

I have built several major instruments:
QUIRC – the largest IR camera in the world, back in 1994.
NIRI – the Gemini Near-Infrared Imager
HiCIAO – the Subaru Hi-contrast Coronographic Imager for Adaptive Optics

I am a co-investigator on the JWST NIRCam science team, and responsible for the GTO projects on exoplanet spectroscopy and interstellar ices.

My astronomical research has recently concentrated on eruptive variability in young stars, and the relationship between such variability and mass outflow
from YSOs.

Teaching

I am teaching both in the UH Manoa astronomy graduate program and in the UH Hilo undergraduate astronomy program.

My UH Manoa graduate course, ASTR 634, offers a broad overview of the technologies involved in astronomical instrumentation, with an emphasis on optical and infrared detectors, optics, and cryogenic design.

The UH Hilo undergraduate course (ASTR 450) is part  of a 3-course series on instrumentation, and focuses on detector technology with an element of laboratory experiments.

Activities

Besides my research and teaching activities, I am serving the IfA in my role as Associate Director of the IfA division in Hilo. Since being established as a division of the IfA in 2000, the IfA Hilo has grown into a well functioning branch of the IfA, concentrating on instrumentation and technology development.
