Michael J. Armstrong

Associate professor of operations research, Goodman School of Business, Brock University

My discipline is operations research. It uses mathematical models to analyze and improve the performance of systems in business and elsewhere.

Much of my research uses models of military combat to investigate topics concerning international security and military history. I have studied missile warfare at sea (e.g., anti-ship cruise missiles) and rocket defenses on land (e.g., Israel's Iron Dome). I have also worked with historians to reexamine key battles from the past (e.g., Balaclava, Gettysburg, and Coral Sea).

I similarly collaborate on research about university teaching and learning. We want to help university students make better decisions about their studies. We have examined how students respond to feedback about their grades and how they perform when repeating courses.

More recently I have been studying Canada's cannabis legalization. I am particularly interested in how government regulations interact with business practices to either support or undermine policy objectives.

I have been a Fulbright visiting research chair at Norwich University and a visiting professor at the U.S. Naval Postgraduate School.

Most of my research papers are available on Brock University's Digital Repository:

I teach courses in quality improvement, game theory, and operations management. My professional certifications are from the American Society for Quality.

I like helping the news media explain complex issues to the public. I have done more than 300 interviews with radio and print journalists, and occasionally comment via Twitter.
