Dr Audard works on star formation with a multi-wavelength observational perspective, including machine learning techniques. He was one of the 3 partners in the NEMESIS project funded from 2021 to 2025 which has the ambition to reshape our understanding on the formation of stars by employing artificial intelligence methods to interpret the largest, panchromatic data collection of young stellar objects. 

He is a member of the Gaia CU7 team (CU7 Deputy Manager since 2023), and coordinates the work package for young stellar objects for DR4 and DR5. He is also member of the SKACH consortium, which develops science and SRCNet activities around SKAO. He is a co-chair of the SKAO Science Working Group "Our Galaxy". He is furthermore Science Co-I of ATHENA/X-IFU (including the X-CAT), and was appointed to the X-IFU Science Advisory Team in 2024. He is also member of the Science team for XRISM. He also coordinated the AHEAD 2020 TNA for Computational Astrophysics, and the Geneva involvement in the TNA for data analysis, until the end of the project end in Dec 2024. Since 2024, he is a Science Team member of the UVEX NASA mission.

He has worked on ASTRO-H/HITOMI before its demise in 2016. He was active in promoting the SPICA project, which was selected for Phase A studies for the ESA M5 candidate mission but was abruptly removed from competition in late 2020. Further opportunities as cooperation between Europe and the USA are being investigated to launch an infrared astrophysics probe as part of the US Decadal Survey recommendations.

Finally, he is also part-time Executive Secretary of the European Astronomical Society. He is the Vice-President of the Swiss Society for Astrophysics and Astronomy since 2020. He also represents Switzerland in the Board of Directors of the Journal Astronomy & Astrophysics since July 2022 and is part of the Executive Committee since June 2023. He has been elected as Executive Committee member of the Division G "Stars and stellar physics" of the International Astronomical Union for the period 2024-2027.
