Ghilardi began learning to skate in 2007.[1] Competing in ladies' singles, she became the Italian novice silver medalist in March 2013 and earned the junior silver medal in December of the same year.[2] She was coached by Tiziana Rosaspina.[3]
Ghilardi last appeared in ladies' singles in December 2015.[2] In 2016, she teamed up with Filippo Ambrosini to compete in pair skating.
2016–2017 season
Making their international debut, Ghilardi/Ambrosini won the bronze medal at the 2016 CS Lombardia Trophy in September. They took bronze at the International Cup of Nice a month later. In December, they became the Italian national bronze medalists. They placed 14th in the short program, 11th in the free skate and 11th overall at the 2017 European Championships, which took place in January in Ostrava, Czech Republic. They trained under Rosanna Murante and Tiziana Rosaspina in Bergamo.[4][3]
2017–2018 season
Ghilardi/Ambrosini placed 8th at the 2017 CS Warsaw Cup in November. The following month, they repeated as national bronze medalists. They won silver at the Toruń Cup in January and bronze at the International Challenge Cup in February.
2018–2019 season
Ghilardi/Ambrosini competed at several Challenger events at the beginning of the season, including taking the silver medal at the 2018 CS Inge Solar Memorial. They won the silver medal as well as the Italian Championships and were sent to the 2018 European Championships, where they finished in ninth place. At their first World Championships, they finished nineteenth among the nineteen competitors.
With the pandemic continuing to affect events, Ghilardi/Ambrossini started their season off at the 2020 CS Nebelhorn Trophy, which was only attended by pairs teams training in Europe.[8] They were third after the short program, and after the withdrawal of Hase/Seegert, the leaders after that segment, they narrowly won their first Challenger Series title over silver medalists Hocke/Kunkel.[9] They were scheduled to compete on the Grand Prix at the 2020 Internationaux de France, but the event was cancelled due to the pandemic.[10]
At the Italian championships, Ghilardi/Ambrosini won the silver medal. Later, they were named to their first Olympic team.[17] Competing first at the 2022 European Championships, Ghilardi/Ambrosini placed fourth in the short program. They were fifth in the free skate and dropped to fifth overall. Ghilardi said it was an emotional moment for them to have made the final group of the free skate alongside the elite Russian teams.[18]
Competing at the 2022 Winter Olympics in the pairs event, Ghilardi/Ambrosini placed sixteenth in the short program after Ghilardi fell twice, one of those being on her triple Salchow attempt. They were the final team to qualify for the free skate.[19] They moved up to fourteenth overall in the free.[20] The team was scheduled to finish the season at the 2022 World Championships, but withdrew after Ghilardi tested positive for COVID.[21]
2022–2023 season
Ghilardi/Ambrosini won gold at the 2022 CS U.S. Classic in their first major competition of the season and their second ever Challenger title.[16] On the Grand Prix, they placed fourth at the 2022 Grand Prix de France, 5.01 points back of bronze medalists Hocke/Kunkel.[22] Despite missing the podium at their first event, they remained in contention to make the Grand Prix Final heading into their second, the 2022 Grand Prix of Espoo. In a relatively weak field, Ghilardi/Ambrosini set a new personal best in the short program (67.31), leading that segment by over four points.[23] They won the free skate as well, setting a new personal best in total score (189.74), and taking the gold medal over Germans Efimova/Blommaert by almost twenty points. This was the first Grand Prix win for an Italian pair since 2013, and qualified them to the Grand Prix Final, to be held on home ice in Torino.[24][25] They finished fifth at the Final.[26]
After winning their fifth consecutive national silver medal, Ghilardi/Ambrosini competed at the 2023 European Championships in Espoo. With Russian pairs banned from competing due to the Russo-Ukrainian War, the podium at the European Championships was considered far more open than in recent seasons. Ghilardi and Ambrosini both made errors in the short program, finishing fifth in that segment.[27] They went on to win the free skate, rising to second overall. With their compatriots, Italian national champions Conti/Macii, taking the gold medal in an historic first for their country, Italian pairs had the top two places on the podium. These were only the second and third pairs medals for Italian teams in the nearly century-old European pairs competition.[28]
2023–2024 season
Ghilardi/Ambrosini began the season with a fifth-place finish at the 2023 CS Lombardia Trophy.[16] They won a silver medal in their second Challenger appearance of the season, the 2023 CS Finlandia Trophy, before winning the Diamond Spin.[29][16] They started the Grand Prix at the 2023 Cup of China, placing second in the short program.[30] They were second as well in the free skate despite Ghilardi falling on her triple Salchow attempt, and won the silver medal. Ghilardi said afterward that it "was hard today, and we are proud of our performance, and how we pushed until the end of the program."[31] At the 2023 NHK Trophy, they placed fourth in the short program after both made jump errors, but rose in the free skate to win the bronze medal.[32]
Ghilardi/Ambrosini finished the Grand Prix with the same placements as fellow Italian team Beccari/Guarise and Hungarians Pavlova/Sviatchenko, winning the tiebreaker on cumulative scores to be the sixth qualifiers to the Grand Prix Final.[33] They finished fifth at the Final.[34]
After winning their first Italian title, Ghilardi/Ambrosini competed at the 2024 European Championships, coming fifth in the short program after losing levels on their step sequence and death spiral elements. A second-place free skate lifted them to third overall, taking the bronze medal. Ghilardi called it "the best skate of the season for sure."[35]
2024–25 season
During the off-season, Ghilardi and Ambrosini worked with their choreographers to create a new short program to the song "El Tango de Roxanne" from Moulin Rouge!, with the intention of depicting the worldwide social issue of violence against women.[36]
Ghilardi and Ambrosini then went on to win the gold at the 2024 Diamond Spin for a second consecutive time.[38] Going on to compete on the 2024–25 Grand Prix circuit, Ghilardi and Ambrosini placed sixth in the short program at the 2024 Grand Prix de France, but third in the free skate, allowing them to win the bronze medal. They followed this up with a second bronze medal at the 2024 Finlandia Trophy.[16]
Although they were initially named as alternates to compete at the 2024–25 Grand Prix Final, they were later called up to compete following the withdrawal of Deanna Stellato-Dudek and Maxime Deschamps.[39] Despite Ambrosini dealing with a leg injury, the pair took the opportunity to compete at the event, where they finished sixth. Two weeks later, they won the silver medal at the 2025 Italian Championships behind Conti/Macii.[38][40]
