Galaxy evolution
How giant galaxies grow, merge, rotate, and transform across cosmic time.
Explore →I study the motions of stars to reveal how dark matter, stellar mass, and supermassive black holes shape the most massive galaxies in the nearby Universe.
Galaxies carry a record of their own formation. Their light, shape, and stellar motions let us reconstruct histories that unfolded over billions of years.

After completing her Ph.D. in Astronomy at Texas A&M University, she began teaching Physics I and II at Wharton County Junior College. Her broader work includes mentoring students, organizing public astronomy, supporting underrepresented scientists, and helping build new pathways for astronomy education in Ecuador.

Three ways into Silvana’s work: a scientific result, a public explanation, and a community built around curiosity.
Orbit-based modeling measured a central black hole of 1.7 billion solar masses—and showed why a galaxy’s true three-dimensional shape matters.
