Joaquin Vieira

Biography

Professor Vieira is an observational cosmologist who works across the electromagnetic spectrum. His scientific interests include: the cosmic microwave background, experimental tests of inflation; dark matter; dark energy; gravitational lensing; high redshift galaxies; instrumentation.

He builds experiments, conducts cosmological surveys, and performs observations of the distant Universe. He works with data from the South Pole Telescope (SPT), Dark Energy Survey (DES), Hubble, Spitzer, Chandra, and ALMA.

He is currently helping to build future mm and sub-millimeter facilities, pondering the cosmic evolution of dust and ionized carbon, and working to detect signatures of inflation through polarized measurements of the cosmic microwave background (CMB).

Prof. Vieira is currently looking for graduate students to work on the following projects:

1) Analysis of South Pole Telescope (SPT) survey data.

2) Observations of strong gravitationally lensed galaxies at high-redshift.

3) Development of cryogenic optics for next-generation CMB experiments.

4) The Terahertz Intensity Mapper (TIM), a NASA-funded balloon project to build and fly a 2-m FIR telescope around Antartica and make a 3D map of the Universe with the redshifted 158 micron ionized carbon line.

Students are welcome and encouraged to drop by with questions about science, instrumentation, or available research projects.

I am always looking for undergraduates to work on analysis and instrumentation projects. I prefer taking on promising students in their first or second year. It's best to just come chat with me during office hours. Come prepared with a CV, some background reading, and questions. Students from traditionally underrepresented groups in science are encouraged to inquire about research opportunities in my group.
