Michael Richard Johnson

At WPI I have taught a variety of courses ranging from Calculus, Statistics, and Probability at the undergraduate and graduate level.  With help from the ATC (Academic Technology Center) I use course capturing to record my lectures and keep an eye on advances in technology to aid student learning.

I completed my PhD in Economics at Clark University in October 2012. My dissertation explored theoretical models for free and open source software. Analysis of two-sided markets (programmers and users) and motives for code forking (a split in the programmer community) were highlighted in separate papers.

My MS Thesis at WPI used graph theory and probability to generate a most probable cyclic-free paths (an extension of Dijkstra’s algorithm) to estimate probability of fire spread.
