Alexander was born in Moscow into a family with a well-established musical tradition. He made his concerto debut at the age of eight, and the same year moved to study at the Yehudi Menuhin School where he is now an Associate Artist. Lord Menuhin was his inspiration throughout his school years, and they performed together on several occasions. Following a three-year residency at the Lincoln Center in New York through the prestigious Bowers Program of the Chamber Music Society of Lincoln Center (CMS), in 2016 Alexander received the Lincoln Center Emerging Artist Award, and now retains a position on the CMS artist roster, making several visits annually to perform at the center. Also, an alumnus of The Royal Academy of Music in London and the Kronberg Academy, Germany, his outstanding talents as soloist, orchestra director, and chamber musician have attracted accolades and won many awards, including 1st prize at the 2011 Trio di Trieste Duo Competition alongside pianist Wu Qian, and he is now increasingly in demand worldwide across multiple roles.

He is much in demand as a director and has worked with Australian Chamber Orchestra, Norwegian Chamber Orchestra, Amsterdam Sinfonietta, Liszt Chamber Orchestra, London Mozart Players, Lithuanian Chamber Orchestra, New York Chamber Players, Camerata Zurich, Arctic Philharmonic Chamber Orchestra and the Romanian Sinfonietta. Alexander is a founding member of the award-winning Sitkovetsky Trio with whom he has performed worldwide. The Trio won the BBC Music Magazine award for Chamber Music in 2022. He also tours regularly as a permanent member of the Julia Fischer string quartet. Alexander plays the 1679 ‘Parera’ Antonio Stradivari violin, kindly loaned to him through the Beare’s International Violin Society by a generous sponsor.
