<span style="font-size: 12pt; vertical-align: baseline;">Mr. Ross earned his Bachelors of Science in Physics (2015) from the University of Michigan - Flint and Masters of Science in Physics (2018) from the University of Toledo where he completed his research
project on the structure of stellar clusters in the M33 galaxy. While pursing his degrees, he worked at both the Sloan*Longway Planetarium (2015-2016) in Flint, Michigan and the Ritter Planetarium (2016-2018) in Toledo, Ohio. Mr. Ross has begun the position
of Planetarium Manager and Instructor at Texas A&M University-Commerce.</span></p>

<span style="font-size: 12pt; vertical-align: baseline;">Star clusters provide a testing ground for a multitude of astrophysical theories. Our theories of gravitational dynamics can be studied through the kinematics of star clusters. As a whole, star clusters
are used to trace out the structure of their host galaxies. This work measures the structural parameters of clusters in the Triangulum Galaxy (M33) to determine if clusters underfill, fill, or overfill their Roche lobes and fit astrophysical models to calculate
the cluster's tidal radii.</span></p>
