Katie is involved in several the firm’s practice areas, including securities fraud, corporate governance, and advisory services. She is currently leading the teams prosecuting securities class actions against The Kraft-Heinz Company, The Boeing Company, Six Flags, and Novo Nordisk. 

Katie played a key role in two of the firm’s largest cases, both of which settled near trial for billions of dollars on behalf of investors. In In re Merck Securities Litigation, she was a leader of the small trial team that achieved a $1.062 billion settlement. This settlement is the second largest recovery ever obtained in the Third Circuit, one of the top 10 recoveries of all time, and the largest recovery ever achieved against a pharmaceutical company. She was also a member of the trial team prosecuting In re Bank of America Securities Litigation, which resulted in a recovery of $2.425 billion, the single largest securities class action recovery ever resolving violations of Sections 14(a) and 10(b) of the Securities Exchange Act and one of the largest shareholder recoveries in history. Katie was also a leader of the team that led the securities litigation concerning Wilmington Trust, which resulted in a $210 million recovery for the class.  Most recently, Katie led the teams prosecuting the securities class actions against Spectrum Brands, Inc. (which recently settled for an undisclosed sum) and FleetCor Technologies, (which settled for a $50 million recovery for FleetCor shareholders).

Katie has also been part of the trial teams in numerous other securities litigations that have successfully recovered hundreds of millions of dollars on behalf of injured investors. She led the team that recovered $74 million in the take-private merger litigation San Antonio Fire and Police Pension Fund et al. v. Dole Food Co. et al., and served as a senior member of the teams that recovered $210 million in In re Salix Pharmaceuticals, Ltd. Securities Litigation, and $216.75 million in In re Washington Mutual Securities Litigation.  Some of her other prominent prosecutions include In re Bristol-Myers Squibb Co. Securities Litigation, which resulted in a recovery of $125 million; and In re Biovail Corporation Securities Litigation, which resulted in a recovery of $138 million and represents the second largest recovery in any securities case involving a Canadian issuer.

Katie’s success has earned her many recognitions, including being named a “Litigation Trailblazer” by The National Law Journal. She has been recognized as a national “Rising Star”  and "Titan of the Plaintiffs Bar" by Law360 for her work in securities litigation and, in 2016, 2017, 2018, 2019, and 2020 was named to Benchmark Litigation’s “Under 40 Hot List,” which recognizes her as one the nation’s most accomplished legal partners under the age of 40.
