Prof. Dr. Thomas Werlen is the Managing Partner of the Swiss office. Thomas is recognized as one of the top attorneys in Switzerland reflecting his unique experience at the highest level with law firms in New York and London, as well as in-house as Group General Counsel and Member of the Executive Committee of global pharma company Novartis. He has been involved as lead counsel in some of the highest profile civil and criminal matters in Switzerland.

Thomas’s practice focuses on white collar cases and corporate investigations as well as on complex litigation and arbitration, often involving multiple jurisdictions.

Thomas regularly represents clients in high-stakes white collar matters. For instance, he has represented a global sports organization in criminal investigations conducted in the U.S. and Switzerland. In the same vein, he represented several major Swiss banking and financial institutions in matters adverse to Swiss and U.S. authorities in connection with the US Swiss Tax Program or with the fall-out of the “Panama Papers”. Thomas is also advising a number of high-profile clients in connection with 1MDB, PDVSA and Lava Jato related criminal and regulatory investigations, including major financial institutions in Switzerland and a large Swiss-based commodities trading company

Thomas’s dispute resolution practice focuses on various industries including but not limited to the financial industry, the commodity industry, international sports, the industrial & high tech sector and the arts and entertainment industry. Recently, Thomas has been instructed to represent a large number of AT1 bondholders holding multiple billions of AT1 bonds in the Credit Suisse – UBS takeover (see here). Additionally, he advised the majority shareholder in a multibillion cross-border acquisition dispute, a Swiss private banking group in a series of complex financial and regulatory disputes in the U.S., Europe and Asia and a major telecom operator in Switzerland in a multi-billion Swiss francs takeover dispute. Thomas is also providing strategic and legal advice on important business decisions to several ultra-high net worth individuals and their companies.

In the area of international sports, Thomas is one of Switzerland’s go-to lawyers for clients involved in high-profile cases, including in the areas of football, boxing, basketball, field hockey and car racing.

Switzerland’s leading business newspapers have recognized Thomas as one of the country’s top lawyers – including the Financial Times, Neue Zürcher Zeitung, Bilanz and Handelszeitung, who describe Thomas as “among Switzerland’s foremost litigators” , among “the select elite of Swiss business lawyers”, and “highly experienced in cases involving prosecution by both US and Swiss authorities”. The Handelszeitung called Thomas “The Specialist for Conflicts”. Clients praise Thomas for his “ability in high-stakes negotiations” and describe him as a “stellar operator” and a “goal-oriented litigator”, who has “a rapid understanding of complex situations and an excellent network”, a lawyer who gives “fast and to-the-point advice” and is “very professional, with top-class” (Legal 500). Moreover, clients state, that Thomas is “very clever and always has a tactic or strategy” and, that he is “always very sound in his advice”. They also recognize Thomas for his “specialist knowledge, market knowledge and also strategic knowledge” (Chambers and Partners). Thomas is ranked in both Chambers Europe and Chambers Global, where sources applaud him for being “a very precise lawyer with perfect legal skills and who works very strategically”.

Prior to joining Quinn Emanuel, Thomas served as Group General Counsel and Member of the Executive Committee of global pharmaceutical company Novartis. In this capacity, he oversaw a global team of over 750 employees spread across 140 jurisdictions, covering all areas of litigation affecting a multinational company with a U.S. listing. Recognizing his transformative work at Novartis, Thomas was awarded the Golden Peacock Global Award for Corporate Governance, named a finalist for “In-House Lawyer of the Year” by The Lawyer and a “transformative in-house lawyer” by The Financial Times.

Before joining Novartis in 2006, Thomas was a Partner in the U.S. law group of Allen & Overy’s London office, specializing in U.S.-related derivatives, capital markets and M&A transactions for European-based clients. Prior to that, he was an Associate at Cravath, Swaine & Moore and Davis Polk & Wardwell in New York and London, respectively. During this time, Thomas’s practice covered a wide range of areas, including banking, debt and equity capital markets transactions (both SEC registered and 144A), public and private M&A transactions, structured finance, derivatives and regulatory capital-related issues. He was repeatedly named as one of the leading U.S. international capital markets practitioners by various leading magazines.

Thomas holds Lic. iur. and Dr. iur. degrees in law from the University of Zurich and a Master’s Degree (LL.M.) from Harvard Law School. He has been a member of the Zurich bar since 1991 and a member of the New York bar since 1997. In 2012, he became Privatdozent (habilitated lecturer) for finance and capital markets law at the University of St. Gallen.

On August 1, 2019, Thomas became a full Professor for finance and capital market law at the University of St. Gallen. He also lectures on corporate law and corporate governance. In addition, Thomas teaches finance and capital markets law in post graduate courses at the University of Zurich.

Since 2012, Thomas has been a Member of the Panel of Experts of P.R.I.M.E. Finance. In 2013, he began serving on the Appeals Board of the SIX Swiss Exchange AG. Due to his expertise in developing corporate governance and legal strategies across the globe, Thomas regularly appears as a panelist or keynote speaker at international seminars and conferences, features on TV and radio shows and attracts regular press coverage, see for example the January 11, 2021, interview with Thomas on Swiss Television about President Trump’s judicial appointments and their implications (Link for interview: and link for article
