Assoc.Prof. Guillermo Martin

Associate Professor Head of the integrated optics and active interferometric beam combiners activity in the Instrumental Research Group at IPAG
Université Grenoble Alpes


Dr. Guillermo Martin works for Institute for Planetary sciences and Astrophysics and his group work on novel instrumentation to support the other groups of the institute. More concrete research topics: CHARM (Contrast High Angular Resolution spectro-iMaging) is a research team that collates the IPAG expertise in instrumentation to research, develop and bring new technologies for high angular resolution, high spectral resolution and high contrast imaging in the optical. The team initiates and benefits from the technological advances of its industry partners, with applications going well beyond astronomy. Observations in astronomy and planetary sciences require highly specific instrumentation that is not available off-the-shelf. Instrument development must be tightly connected to the identified scientific goals. Research labs identify, select, test new instrument concepts using the latest technologies to enable major advances in performance and open up discovery space. The activity of the team covers high angular resolution in visible-IR, high contrast interferometry, imaging spectrometry, high resolution mass spectrometry. Our activity has led us to develop successfully several instruments for the community such as PIONIER/VLTI, GRAVITY/VLTI, etc. Our expertise is also valued beyond astronomy through the startups we helped initiate (Alpao, RSS, FLI).
