By winning several Belgian championships and the World Cup in 2002, Jérôme graduated to professional competition in 2003 in which he contested Formula Renault 1.6 Belgium.
After notching five victories in the series en route to his maiden single-seater championship title, the Belgian continued to impress, taking fourth in Formula Renault 2.0 Italia and third in its Winter Series counterpart in 2005, later winning International Formula Master in 2007.
For 2008, Jérôme graduated to the GP2 Series with DAMS and over three seasons, accumulated seven podiums, one victory and the vice-champion title in the Asian series which earned him a place on the grid for the 2011 Formula 1 World Championship.
Making 20 race appearances with Virgin Racing and the Lotus F1 Team, Jérôme left motorsport’s top tier at the end of 2012 to join Formula E in time for its opening 2014/15 season in which he represented Dragon Racing.
Success quickly followed, with Jérôme taking his maiden Formula E victory at the 2015 Berlin E-Prix before recording back-to-back podium finishes in London to place fourth in the inaugural Drivers’ Championship with 113 points.
Remaining with Dragon, Jérôme later won the Season 2 Mexico City E-Prix and took three further podium finishes prior to joining Mahindra Racing in 2018 with whom he won the Season 5 Marrakesh E-Prix and took one podium.
After deciding to retire from professional competition in 2020, Jérôme joined ROKiT Venturi Racing as Deputy Team Principal, with the Monegasque marque benefitting from the expertise of one of Formula E’s most experienced and decorated drivers.
