He was hired by the Big Nerd Ranch in September 2005 after asking too many annoying questions at the Cocoa Bootcamp that March.
When not slaving away at his computer, Mark puts his Masters Degree in Geophysics from Stanford University to good use by pounding away at rock walls in quarries, searching for elusive treasures for his mineral collection. (This activity is why he never mocks anyone else's hobbies.) A passionate Chicago Cubs and Penn State fan, Mark enjoys playing any sport where someone keeps score.

Juan Pablo Claude
Django Instructor Juan Pablo Claude is originally from Santiago, Chile and came to the US to attend graduate school in chemistry at the University of North Carolina at Chapel Hill. After earning his Ph.D., Juan Pablo became a professor at the University of Alabama at Birmingham, teaching and doing research in the area of physical inorganic chemistry. In his research, Juan Pablo often had to write data acquisition analysis programs, leading to his interest in computer programming and technologies. After spending several years in academics, Juan Pablo decided to make a career out of computers. He joined the Big Nerd Ranch in late 2005 as a Cocoa and Django programmer.
Juan Pablo cut his teeth programming in C for PC's running DOS to squeeze data out of recalcitrant instruments during graduate school. He then moved on to write data analysis applications in C++ for Windows. When OS X was released he was immediately compelled to return to the Mac and he has never looked back ever since. These days he is delighted to write Objective-C and Python code in such a cooperative platform.
