Gilles P.P.L. Otten

Support Scientist



Support Scientist for the ELT/METIS instrument at Institute of Astronomy & Astrophysics, Academia Sinica (ASIAA) in Taiwan. Involved in the HiRISE project at LAM, Marseille, to combine high contract imaging and high dispersion spectroscopy at the VLT, and the MASCARA project at Leiden Observatory which searches for transiting exoplanets around the brightest stars. PhD on the prototyping, lab-testing and on-sky demonstration of a new type of broad-band coronagraphs. Amateur-genealogist with an interest in genetics as a tool to research family history.

Combining high contrast imaging with high dispersion spectroscopy


The Multi-Site All-Sky CAmeRA searches for transiting exoplanets around the brightest stars in the sky.

Vector APP

The vector Apodizing Phase Plate coronagraph (vAPP) surpresses starlight on both sides of a star using an achromatic pupil-plane coronagraph based on liquid-crystal technology. This enables an improved detection and characterization of exoplanets and their atmospheres.

Genetic genealogy

DNA is a powerful tool in family research and has provided valuable clues in research of my family’s origins.
