Interests

Main Page

• Radiotelescopes

  • I'm currently working at the Cosmic Background Imager (CBI) of the California Institute of Technology

• Cryogenic Systems

  • At the CBI we're running Grifford-McMahon fridges to cool down our receivers to 6ºK, closed cycle He gas.

• Low Noise Amplifiers

  • The LNAs of the CBI receivers are HEMTs operating in the 26-36 GHz frequency window.

• Site testing for telescopes

  • I'm involved in the site testing for the Cornell-Caltech Atacama Telescope (CCAT) and the CLOVER (U. of Cardiff, UK).

• Antennas

  • I did simulations of a 2D antenna with FDTD in Matlab. (pdf)
