O’Melveny Worldwide

Nexus Sea is a versatile litigator and trial lawyer who advises and defends a wide spectrum of Fortune 500 companies, including clients in the financial services, pharmaceutical, energy, and tech industries. Companies call on Nexus for his responsive service and goal-focused guidance, trusting him to devise creative solutions, build the right teams, and craft winning strategies that advance their business goals. 

Nexus represents some of the world’s best-known companies in a variety of areas, including multimillion-dollar commercial disputes and class actions, product-liability and mass-tort litigation, and internal investigations. He recently defended a leading medical device manufacturer in a high-profile state attorney general consumer protection action. He also played a prominent role on the court-appointed counsel team to the Securities Investor Protection Act Trustee for the liquidation of Bernard L. Madoff Investment Securities LLC, and represented various foreign claimants in connection with allegations of corruption and money laundering in the largest civil forfeiture action brought under the Department of Justice’s Kleptocracy Asset Recovery Initiative.

A veteran of product-liability and mass-tort litigation, Nexus served as a member of the lead national team that defended an international consumer products company against numerous state court consumer product cases involving talcum powder. He also played a key role in defending a Fortune 500 bank and premises owner in hundreds of toxic tort personal injury suits arising from the 9/11 terrorist attacks.

Bringing his background in mathematical sciences to bear on the intersection of law and cutting-edge technology, Nexus is currently advising clients on Artificial Intelligence-based risk, including pre-litigation counseling related to the implementation of large language models. Nexus’s pioneering work in this space helps companies prepare for and navigate a looming challenge: the impact of AI on existing legal regimes, including product-liability law.

The Metropolitan Black Bar Association honored Nexus with its prestigious “Private Practitioner of the Year Award” in 2023. He is also a recipient of the National Bar Association’s 2017 “40 Under 40 Nation’s Best Advocates Award,” and has been routinely recognized by Super Lawyers as a “New York Metro Rising Star.” As a founding member of “1844,” an association of African American male attorneys that focuses on promoting collaboration, business development, and mentorship, Nexus mentors various law students and young lawyers on how to build community and find success in private practice.
