Daniel studied physics as an undergraduate at Columbia University. Later, he earned a Master’s in Computer Science from NYU, where he studied distributed systems, operating systems, databases, machine learning, and several advanced security classes — including application security, network security, and offensive security. He also served as a teaching assistant for NYU's flagship graduate course, Internet Security and Privacy.
While at NYU, Daniel was part of the OSIRIS cybersecurity research lab at the Tandon School of Engineering, where he contributed to hands-on offensive security research, internal tooling, and advanced red team scenarios.
Daniel holds The Practical Network Penetration Tester (PNPT) certification from TCM Security and is days away from securing two more red teaming certifications from Altered Security (CRTP), Zero-Point Security (CRTO). Each certification focused on a different aspect of Active Directory Attacks demonstrating hands-on experience ranging from Cobalt Strike operations to PowerShell abuse and living-off-the-land techniques for stealth and EDR evasion. But my focus is not on specific tools which change and eventually get detected, but on mastering the attack concepts that persist
He is currently sharpening his skills in malware reverse engineering and exploit development through the RET2 Systems wargame platform, diving deep into memory corruption, shellcode, and system-level exploitation.
