Mathis' practice focuses on German and European antitrust law.

Mathis' international experience across several locations includes merger control reviews, cartel matters, vertical conduct investigations, dominance matters, civil and appellate litigation and advisory work. He has particular experience in in-depth merger reviews before the European Commission, including complex Phase II reviews, and has overseen and managed merger notification processes in a number of jurisdictions, often simultaneously. 

Mathis represents clients across a broad range of key industries, such as chemicals, seeds/agriculture, consumer products, automotive and tech. 

Prior to joining White & Case in 2019, Mathis worked in the Cologne office of a renowned US law firm for five years. During this time, he was involved in a number of high-profile transactions, including Dow Chemical Company's $130 billion merger of equals with DuPont, as well as a number of cartel matters.

Mathis' secondment to a multinational consumer electronics retailer provided him with invaluable insight from an industry perspective.
