Jean-Philippe (JP) Aumasson is a true innovator in cryptography, and especially in the creation of fast, secure and light-weight hashing methods. He co-designed the BLAKE hashing method [here], and which is currently the fastest secure cryptographic hashing function. Along with this, he worked with Daniel J Bernstein on SipHash [here], and created the Cryptography Coding Standard. JP also created the Quark light-weight hashing method, and is also the author of "Serious Cryptography: A Practical Introduction to Modern Encryption" [here].
