at the 2.3 m Wyoming Infared Observatory, and he has noted that
astronomy with space telescopes doesn't interfere as much with his
sleep cycle.

stellar cluster within which these stars live and die, over cosmic ages. The
observations are obtained within the most nearby galaxies, mostly at optical,
infrared and radio wavelengths, but Jacco is willing to use any technique or
object in the sky to answer an interesting question - including solo climbing
remote mountains to gain a closer understanding of our place in the Universe.

Group at Keele University, UK. Her main scientific interest are observational
studies of star formation and young stars. In particular, she is interested in
understanding how the star formation environment influences the formation and
