NHFP Sagan Fellow
Emiel Por headshot

Emiel Por is an NHFP Sagan Fellow at the Space Telescope Science Institute in Baltimore, Maryland. He received a double bachelor's degree in physics and astronomy, and a master's degree in astronomical instrumentation from Leiden University, The Netherlands in 2013 and 2016 respectively. He continued at Leiden University and received his doctorate in 2020 working on advanced instrumentation for the direct imaging of exoplanets for both ground- and space-based telescopes. During his PhD, he developed novel coronagraph solutions such as the single-mode complex amplitude refinement and phase-apodized-pupil Lyot coronagraphs, and methods for post-coronagraphic wavefront sensing. Emiel is also the main developer of the HCIPy (High Contrast Imaging for Python) software package, an open-source, modular Python package for high-contrast imaging simulations for current and future telescopes. Segmented primary mirrors, such as the one proposed for LUVOIR, require that all segments stay aligned to within a few picometers during a coronagraphic observation. Therefore, besides a high-performance coronagraph, high-order wavefront sensing and control will be necessary for future giant segmented space telescopes.

As an NHFP Sagan fellow at the Space Telescope Science Institute, Emiel will work on developing coronagraph solutions that jointly optimize both coronagraphic performance and wavefront sensing and control capabilities.
