i am a theoretical cosmologist and astrophysicist. i am primarily interested in galaxy formation, the development of structure in the universe, and the connection between the dark side of the universe and the observable side.
some of the big questions that drive me:
- what is accelerating our Universe?
- what is dark matter made of?
- how do galaxies form?
a few current questions that interest me:
- is the milky way a typical galaxy? [watch the movies to find out!]
- how are mass and light connected in the Universe?
- what drives the star formation history of galaxies?
- what do we need to know about galaxy clusters to use them to measure the acceleration of the Universe?
kipac research highlights on our work:
- Galaxies Reveal Surprises Statistically
- A Tool To Find Merging Needles In Cosmic Data Haystacks
- Missing Dark Matter Satellites Still Missing
- Life In the Dark Matter Fast Lane
- The Milky Way's Unusual Companions
