Abstract: 
I will present two very different research topics: the sensitivity of 
galactic chemical evolution (GCE) to the s-process in massive stars and our 
experiments studying neutron halo nuclei. The former is a computational 
study, in which I implemented 22 Ne(α,n) reaction rates that we measured at 
Texas A&M cyclotron within nucleosynthesis and GCE simulations. The reaction 
is a critical neutron source for the s-process in the massive stars. I will 
present the impact of our rates on the GCE and how future experiments could 
reduce the remaining uncertainties. In the second part of my talk, I will 
discuss our new approach to constrain the halo properties, such as neutron 
separation energy. We have verified the method with 11 Be (accepted in PRL) 
and now move forward to more exotic halos at FRIB.
