Working virtually in Professor Jeff Filippini’s cosmology group in the physics department analyzing data taken from the sub-orbital, cosmic microwave background (CMB) polarimeter SPIDER (http://jpf.web.engr.illinois.edu/).• Characterized cosmic ray events seen by the SPIDER detectors.• Modeled the cosmic ray energy spectra to aid the SPIDER collaboration in telescope design and limit contamination. • Gained experience with the extract, transform, load (ETL) process in a research context. • Gained experience with a variety of modeling and statistical techniques, such as multivariate regression, correlation, and distributions, in Python with the Numpy, Scipy, and Pandas modules all within the Linux environment. • Produced several plots involving cosmic ray analysis to be used in future SPIDER publications.• Successfully modeled and quantified cosmic ray crosstalk to provide insight on SPIDER's design.• Wrote tutorials with Python to introduce new members of the group to the SPIDER software.Resulted in improved knowledge of SPIDER’s response to cosmic rays, which will be used to inform SPIDER and other collaborations looking to design CMB telescopes. Drafting toward a future publication with the SPIDER collaboration. (First submitted publication, section 3.3: https://arxiv.org/pdf/1711.10596.pdf)

• Working virtually with Matias Carrasco Kind on large-scale, dark-matter-only cosmological simulations.• Identified dark-matter halos found in the simulations using various techniques such as FOF and HOP, computed halo mass functions, and created animations visualizing large-scale structure with matplotlib.• Gained experience with cluster computing techniques to process large data sets in parallel. • Wrote algorithms to identify the bounds of dark matter halos and set limits on large-scale structure• Co-wrote an accepted proposal for 50,000 node-hours (with an estimated value of $31,000) on NCSA’s Blue Waters resource for a cosmological simulation that will run from 13.7 billion years in the past to 70 billion years in the future with 800^3 particles.

• Worked with Professor Joaquin Vieira’s observational cosmology group in the astronomy department at UIUC (http://obscos.astro.illinois.edu/). • Research focused on identifying gravitationally lensed sources by cross matching multi-wavelength data from DES, the South Pole Telescope (SPT) and the Wide-Field Infrared Survey Explorer (WISE) and applying a variety of cuts. • Produced a list of candidate lensed galaxy to be further investigated.• Gained experience with processing large, astronomical surveys with Python. Wrote complex scripts for cross matching positions of galaxies from different astronomical catalogs.• Wrote a senior thesis, made a poster and presented this research during the Fall 2015 semester, which resulted in co-authorship of a journal article (Nord, B., Buckley-Geer, E., Lin, H., et al. 2016, ApJ, 827, 51).
