He possesses distinctive expertise that organically connects accounting, finance, capital markets regulation, and criminal investigation practice. After graduating from Sogang University with a degree in Business Administration, he developed a deep understanding of corporate financial structures and accounting irregularities through his work at Samil PwC and the Financial Supervisory Service, where he handled statutory audits, accounting investigations, and supervision of financial holding companies.
