What I'm Looking For — and What I Bring

I'm looking for…

…and what I bring

a) A group to bounce ideas off

b) A place to keep learning

c) A place to mentor 

d) A group that looks after its people

e) Keep doing Outreach

a) Projects like MARES and the LILA began as conversations

b) Worked on radio, optical/UV, X-ray and gravitational waves — accreting WDs, Exoplanets, Brown Dwarfs, millisecond pulsars, globular clusters, symbiotics and the Sun

c) Co-lead CENCA Bridge ($1.5M Simons Foundation remote internship program)

d) Establishing Multimessenger Astronomy Inclusive Training: two years where the people and the science were the same priority.

e) Ciencia Pal Barrio; Zooniverse; SciX Ambassador; Amateur Astronomy Society Talks

Future Work in GCs
