What do you focus on?

Complex Litigation

I have litigated cases involving a broad spectrum of complex business disputes, including contract, breach of fiduciary duty, business torts, construction, real property disputes, enforcement of non-compete agreements and all types of fraud claims. I have also represented clients in domestic and international arbitrations in a variety of venues, including the ICC, in disputes involving major energy projects, and commercial and financial disputes. Additionally, I regularly counsel clients on ways to avoid or minimize the risks attendant to their businesses and transactions.

Securities and Governance Litigation

I focus on defending officers and directors, broker-dealers, securities issuers and companies in securities fraud claims, SEC enforcement actions and breaches of fiduciary duty. I also have extensive experience with derivative litigation, and litigation arising from changes in corporate control and M&A transactions.


In addition to litigating disputes, I have represented clients in investigations by numerous regulatory authorities. I also have worked on and led numerous internal investigations for clients, including matters dealing with trading issues at financial institutions, employee dishonesty and breaches of fiduciary duty and accounting issues in a variety of industries.

Intellectual Property

I represent companies in a variety of intellectual property disputes including patent, trademark and copyright infringement, licensing disputes, trade secret issues and other types of unfair competition. In addition to experience in traditional court litigation, I have experience with matters litigated before the Patent Trial and Appeal Board under the America Invents Act.

What do you see on the horizon?

The threats to businesses from the loss of competitive advantage—whether through data breach, theft of confidential information and trade secrets or other IP infringement—is growing rapidly. Clients need counsel who can address these threats proactively and, when necessary, litigate them aggressively and practically.
