Mahnu Davar's practice focuses on assisting FDA-regulated entities with complex regulatory and compliance matters. He has represented early stage medical technology companies, clinical labs, major academic research institutions, and some of the largest multinational drug and device companies in the oncology, ophthalmology, pain, and diabetes care spaces.

Mr. Davar routinely counsels clients on the regulatory and compliance aspects of promotional launch campaigns, clinical research, educational grants and charitable giving, manufacturing and supply chain, deal diligence, and other mission-critical activities. He has conducted significant compliance investigations and audits for business operations in the US, Europe, and Asia, and has extensive experience defending companies in criminal and civil healthcare fraud investigations. He has also assisted clients to prepare for and navigate state and federal regulatory inspections. Mr. Davar's practical approach to counseling in these areas is informed by his experience working first-hand with business leaders as a "secondee" in the legal departments of several leading multinational drug and device companies.

Mr. Davar is a lecturer at the University of Pennsylvania Law School, a Fellow of the Salzburg Global Seminar, and a former Fulbright Scholar to India. Prior to joining the firm, Mr. Davar worked as a law clerk at Wyeth Pharmaceuticals.
