Biographic Notes
Andrew Humphrey obtained his bachelor and PhD degrees from the University of Hertfordshire, and has worked at various institutes in Europe, the Americas and Asia, before moving to Porto with a Marie Curie Fellowship. Andrew's research interests include the formation/evolution of galaxies as probed by various phenomena, particularly Lyman-alpha nebulae, powerful active galaxies, and dusty star-forming galaxies at high-redshifts.
