Abstract: How galaxies form and evolve is a key
science question to be addressed in the upcoming decade. A central
area of research within galaxy evolution revolves around how galaxies
start forming stars, how star formation is regulated and how the
growth of central black holes (Active Galactic Nuclei) affect the star
formation of a galaxy. Specifically I study the physical processes
that affect the star formation history of nearby galaxies through
observations of atomic Hydrogen (HI). HI provides the initial fuel
from which stars can form and due to its diffused nature, is an
excellent tracer of the internal and external physical processes that
are currently impacting on the evolution of a galaxy. As we strive to
map the Universe further, deeper and at greater resolution, we are now
entering a new era of massive survey datasets that require the
investigation of new methods of analysis. In this colloquium, I will
describe some of the science questions that is currently keeping me up
at night, in addition to some of my investigations into alternative
methods such as citizen science and the application of machine
learning towards maximising the science outcomes from the upcoming
ASKAP all-sky surveys such as EMU and WALLABY.
