About

Training to become a successful, top-notch lawyer, with meaningful experience in various practice areas. Despite graduating from NYU in 2021, I have been intentional about gaining significant experience in many different practice areas and industries. My hard work, commitment, and attention to detail - instilled in me, since 7 years old, during my time as a semi-professional classical pianist attending the Juilliard Pre-College Program. During law school I craved gaining litigation experience and being a research assistant to multiple professors for multiple semesters, being exposed to local, state, federal, and international laws. I have substantial litigation experience on both sides of various specific practice areas: • criminal • human rights • securities fraud class actions (3+yrs, both sides) • antitrust and unfair competition class actions (3+yrs, both sides) • data breach class actions (2+yrs) • consumer protection class actions (2+years) • patent defense litigation (automotive, high-tech, and generic pharmaceuticals) • patent prosecution in South Korean Patent Office I also have substantial knowledge of numerous industries, such as: • automotive parts • emerging technology • natural resources • life sciences & pharmaceuticals • banking • securities • data privacy and cybersecurity systems and infrastructure • artificial intelligence/machine learning • telecommunications • social advertising • corporate governance I consistently seek new opportunities to leverage, enhance, and expand my skills and experience, and I always enjoy the chance to connect with others!
