IRT Saint Exupéry kicks off a series of portraits devoted to the men and women who best represent the institute: its researchers. Their high-level skills and wealth of experience contribute hugely to IRT Saint Exupéry’s performance and unique position, which is so crucial for its members and partners.
Olivier Liandrat, age 30, is a computer science engineer specialising in image processing and machine learning. He is seconded to IRT Saint Exupéry by the SME Reuniwatt. From solar rays with photovoltaic to laser beams with optical communications, Olivier keeps his head in the clouds!
Can you tell us about your career so far?
After my end-of-course internship at Reuniwatt, a start-up based on Réunion Island, I was the first person they hired. My work focused on analysing images of the sky recorded from the ground with observation cameras in order to deduce changes in cloud cover. After three and a half years, I wanted to return to mainland France, just when Reuniwatt had started having closer links with IRT Saint Exupéry, and I was asked to join the ALBS project in 2015.
What area of expertise at Reuniwatt was IRT Saint Exupéry interested in?
Could you tell us a little more about ALBS and Reuniwatt’s role?
What noteworthy results have been obtained by IRT Saint Exupéry's members?
What do you like about your work at IRT Saint Exupéry?
What I like about IRT Saint Exupéry is that we’ve got more time to work on the specifications, and to think about the methodology and really refine our product. With the resources allocated to the project, we have achieved things together that our SME could never have done by itself. IRT has played the role of facilitator, providing access to major customers by factoring in the risk-taking that is linked to R&D work. Being housed alongside Airbus Defence & Space and Thales Alenia Space employees means we can understand their challenges and needs better. It’s a very enriching experience.
There are lots of opportunities with the ALBS project: for example, CNES invited me to present our solution at a CCSDS meeting in October 2018. This international committee deliberates on the weather measurements to be made on an optical reception station to contribute to the drafting of a volume of recommendations.
