About Me

Hi there! My name is Danny Price, and I'm a postdoctoral researcher at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. Before this, I did my DPhil. (PhD) in astrophysics at the University of Oxford, and also worked briefly at ICRAR in Western Australia.

Detecting the dark ages

I'm currently working on the Large Aperture Experiment to Detect the Dark Ages, or LEDA. We've built a 256-antenna array along with a powerful GPU-based correlator in Owen's Valley, California. We're looking for highly-redshifted Hydrogen in the early Universe, and will image the entire sky at radio wavelengths.

Radio astronomy instrumentation

I work mainly on digital instrumentation: designing and implementing signal processing systems for radio telescopes. I work a lot with FPGAs and I'm an active part of the CASPER collaboration. I've helped build instruments at the Parkes (HIPSR), Owen's Valley (LEDA), Medicina (BEST-2), and Tidbinbilla (TAMS) observatories.


HIPSR is a spectrometer and pulsar machine for the Parkes 21cm multibeam receiver.


LEDA is a low-frequency array of 256 antennas in Owen's Valley, California.


D-PAD was a 16-element aperture array that I built as part of my PhD project.

More about me

You might like to check out my publications, or head over to the blog I keep at Passle. You can grab my contact details at the bottom of this page, and links to my github, linkedin and arXiv pages.

Even more? I play guitar, love music and drink too much coffee. I've slowly been exploring the USA, ticking off the states as I go. I enjoy tinkering with web and UI design (thank you bootstrap), speak a little Japanese, and am outrageously good at Mariokart 64.
