Romain Thomas is a security engineer working on the development of new tools to assist security researchers. Author of LIEF, a library to parse and manipulate executable file formats (ELF, PE, Mach-O), he enjoys going back and forth between reverse engineering and tool development to see which part of the process can be automated. He is also interested in (de)obfuscation, software protections and packer. He contributed in the past to the Triton project, especially on de-obfuscation based on symbolic execution.
