Pavlova began her sporting career as a cross-country skier . In 2011 she moved to Novosibirsk and started biathlon training there. In the following year she started for the first time at the youth world championships , where she finished fourth with the relay. In 2014 in Presque Isle , she became the junior world champion in sprinting: as one of only two athletes, she hit all ten targets and prevailed 0.3 seconds ahead of Kazakh Galina Vishnevskaya . With the relay, Pavlova won the silver medal at the Junior World Championships on the side of Viktorija Sliwko and Uljana Kaischewa . At the 2015 Winter Universiade , she won the pursuit race - after finishing second in the sprint - and also won the gold medal with the mixed relay.
At the end of the 2017/18 season , Pavlova made his debut in the IBU Cup , won the sprint in Uwat in this series of competitions and achieved four more top ten results. At the beginning of winter 2018/19 , she qualified for the first time for the Russian World Cup team. At the start of the season on the Pokljuka , she finished eighth in the sprint as the best individual result. In the further course of the winter she was one of the most successful athletes in the Russian World Cup team with regular results in the top 40 points. She was used three times as the starting runner of the relay and won the race in Oberhof in January 2019 together with Margarita Wassiljewa , Larissa Kuklina and Jekaterina Jurlowa-Percht . At the European Championships in Minsk-Raubitschy in 2019 , Pavlova won the title in the single mixed relay alongside Dmitri Malyschko . Shortly afterwards she reached the top ten in four competitions - the three relays and the pursuit - at the World Championships in Östersund . Although Pavlova missed several World Cup races due to illness, including the season finale at Holmenkollen , she was the best-placed debutante as 34th in the overall ranking of the season and was thus named Rookie of the Year by the International Biathlon Union .
In 2019/20 Pavlova competed in the IBU Cup again. In January she won the first sprint race in Osrblie and placed in the top three in other competitions before she became European champion in the first super sprint at the end of February , beating Olena Pidhruschna from Ukraine by almost three seconds.
