If you’re an astrophysicist...

...I’m broadly interested in astrophysics, and am particularly enthusiastic about cosmology.  Recently my work has been on 21cm tomography, which seeks to use the highly redshifted 21cm hyperfine transition to constrain the Epoch of Reionization, the preceding Dark Ages, as well as fundamental physics.  Lately I have focused on figuring out how to get the most out of the data that will eventually come out of a 21cm tomography experiment.  This has meant dealing with issues like radio interferometer calibration, mapmaking, foreground characterization and subtraction, power spectrum estimation, as well as thinking about statistical measures beyond the power spectrum.

If you’re a not an astrophysicist...

...I’m trying understand how our Universe came to be the way it is.  For instance, how many galaxies like our Milky Way exist? Why aren’t there more of them? How did they form anyway? We’re trying to answer questions like these (among many others).  One way to do so is make really, really good maps of how hydrogen is distributed in our Universe.  Once we have that, we can work backwards and figure out what our Universe must’ve done to create a map that matches what we see.

If you’re interested in finding out more about my research, check out my research page.  I also love to teach, so be sure to take a look at my teaching/outreach page.  If you don’t actually know me in real life, you might want to find out who I am by reading about me.  Head over to Random Things for some laughs and other...random things.

Finally, if you’d like to contact me, the easiest way is by email.  Have fun!
