A former Anti-Fraud Specialist, Jonathan fortified financial institutions against fraudulent activities through a comprehensive anti-fraud program. Leveraging his credentials as a Certified Fraud Examiner (CFE) and Computer Hacking Forensic Investigator (CHFI), he implemented prevention and detection strategies, led complex fraud (including cyber-enabled-fraud) and misconduct investigations, and educated stakeholders on fraud risk and cybersecurity threats. His expertise in fraud risk management and cybersecurity safeguarded assets and reputation across the banking and telecommunications sectors. He has since directed investigations into financial fraud, insider threats, misconduct, and cyber-enabled fraud, combining forensic acquisition and analysis with compliance to national and international standards. Jonathan is recognized for leading investigative teams, conducting digital forensics—including mobile and IoT forensics, and delivering defensible findings to regulators, law enforcement, and executive stakeholders.

At the Center for Cybercrime Studies (CCBYERS), Jonathan oversees digital forensic operations, evidence handling, IoT device analysis, and the development of standard operating procedures. He contributed to a Bureau of Justice Assistance (BJA)–funded project building a searchable IoT device database, and currently plays a central role in a NIST-funded initiative establishing a Cybercrime Investigations Laboratory and Research Facility. His technical expertise spans Cellebrite, EnCase, Autopsy, FTK Imager, Belkasoft, Magnet Forensics, and packet analysis tools like Wireshark, supported by Python scripting for automation. He also integrates project management systems to streamline case tracking, inventory, and workflows.

Jonathan holds dual master’s degrees: an M.S. in Digital Forensics and Cybersecurity (John Jay College, CUNY) and a Master’s in Electrical Engineering (Telecommunication Management) from the University of Indonesia, along with a Bachelor of Electrical Engineering from Pancasila University and an Associate Degree in Telecommunications Engineering from Telkom University.
