Monisha took over after Peter Sauber decided to step back from his daily assignment of the team that he founded in 1991.
Sauber had already stated he did not want to run the team after turning 70 next year. However, he will continue in his role as President of the Sauber Group's board of directors.
Team Sauber started in F1 in 1991 with drivers JJ Lehto and Karl Wendlinger driving cars powered by engines built by Ilmor but rebadged as Saubers.
The team is currently sixth in the constructors' championship, 20 points behind Mercedes with five races to go.
Monisha aspired to be an astronaut as a kid. At the age of eight, her family moved to Vienna, where her uncle was employed in the International Atomic Energy Agency.
She secured her bachelor's degree in law from the University of Vienna in 1995 and went on to get a Master's degree in International Business Law from the London School of Economics in 1996.
Monisha got her first job in Stuttgart in Germany and also worked for the United Nations and a few law firms in Germany and Austria. MORE
