I have worked with a professor within my Physics department for almost a full school year now on electron scattering simulations. I run some programs on my computer and analyze them with ROOT. This work has been rewarding as I have learned a lot, but I recently got offered a position in a Lab. I did not apply for this position, but rather a Chemistry professor asked me after his class if I would be interested in joining his lab. His research is on Multivariate Calibration in the field of Analytical Chemistry. He employs a handful of undergraduates and they often go to conferences and they have some publications. The Chemistry Lab offer would have me doing a bunch of coding, analysis, and mathematics. This lab would give me work during the summer as well as during the school year, but my Physics research job does not have funding for summer work. That is because the job is funded through the departments school funds, which are not as high during the summer. Also, my Physics job is 1 on 1 with a professor and I do all the work off of my laptop. The Chemistry offer is an amazing offer, but I do love my work with my current physics job. I plan on going to graduate school to study neutrino or astrophysics (my school doesn't do astro). So, does the topic of my undergraduate research work matter? Which job would be better to get? If this is of any help I am wrapping up my second year at Uni.
