CV

I'm a recently graduated Astronomy & Astrophysics major from the University of Michigan - Ann Arbor. In the Fall of 2021, I'll start as an Astronomy PhD student at Northwestern University.

My research interests include data- and computation-intensive astronomy and galactic dynamics.

This website is intended to serve as a supplement to my CV, containing resources like past presentation slides and posters.


Research Projects

Presentations of these projects can be found below.

Non-Parametric Spherical Jeans Mass Estimation with B-Splines

University of Michigan, Ann Arbor

Excerpt from abstract:
We present a novel non-parametric routine for solving the spherical Jeans equation by fitting B-splines to the 3-dimensional velocity and density profiles of halo stars ... We validate our routine on several progressively more complex and realistic mock datasets.
draft of the journal paper

Star Formation Rate in Merger Galaxies

University of Michigan, Ann Arbor
MDM Observatory - Kitt Peak National Observatory

Excerpt from abstract:
We observe four target merger galaxies in H-alpha to calcualte their star formation rate densities and collect previously observed data giving us their gas surface density. With these two quantities, we can investigate how various merger galaxies stand in relation to non-mergers with respect to the Kennicutt-Schmidt law.

Presentations

Non-Parametric Spherical Jeans Mass Estimation with B-Splines

University of Michigan, Ann Arbor

I presented this work as an iPoster at the DESI Special Session of the 237th AAS meeting in January 2021 where I won a Chambliss Astronomy Achievement award.

I also gave a short talk at the Michigan Institute for Data Science Poster Symposium 2020 where I won the award for Outstanding Undergraduate Poster. I ensured that my content was accessibile for the non-astronomy audience by focusing on the motivations and implications of the work. In 2019 and 2021, I presented similarly accessibile posters at the University of Michigan Astronomy Undergraduate Poster Session.

I recently wrote a short summary of this project (a bite) for the undergraduate research series on astrobites.org

Star Formation Rate in Merger Galaxies

University of Michigan, Ann Arbor
MDM Observatory - Kitt Peak National Observatory

This project was done as part of a University of Michigan course, ASTRO 461. In the observing proposal we describe the motivations, feasability, and target selection.

Other Projects

Website Architect for GHOSTS HST Survey

University of Michigan & Leibniz Institute for Astrophysics

I recently undertook a project rebuilding the Galaxy, Halos, Outer disks, Substructure, Thick disks and Star clusters (GHOSTS) HST survey website. I noted inefficiencies in the source of the current version and designed a rebuild to correct for these and improve expandability. I proposed my rebuild project to GHOSTS P.I. Dr. Roelof de Jong with logistical help from GHOSTS team member and UM professor, Eric Bell. My rebuild employs Jinja, an efficient Python templating engine, to simplify the creation and modification of their webpages.

Hobbies

When I'm not staring into a jupyter notebook, I like to keep myself moving and trying new things. I've made sure to adapt my existing hobbies to a quarantining environment, especially baking and cooking with friends. I've also taken time at home during the pandemic to exercise, both lifting and cardio, and read for pleasure.
