About our authors Dr. William G. Sullivan earned his PhD from the Georgia Institute of Technology in Industrial and Systems Engineering. In his more than 40 years of service to industry and the academy, he made enduring contributions to engineering economy education. A tireless lecturer, he taught engineering economy to more than 10,000 students at 5 major universities (Georgia Tech, University of Tennessee, North Carolina State University, Arizona State University and Virginia Tech). He also had extensive consulting experience with 25 firms in the US.? Dr. Sullivan's 5 textbooks in the field, including Engineering Economy, continue to contribute to the education of thousands of students.
Elin M. Wicks is the owner of Abacus Accounting LLC, an accounting and bookkeeping company focused on empowering small business owners to achieve financial success. She earned a BS and MS in Industrial Engineering from Rutgers University, where her masters research focused on a method of quantifying non-economic factors in monetary terms. During this time, she also developed software tools to assist Cosmair Inc. in improving scheduling and labor recording practices. She went on to earn her PhD in Industrial and Systems Engineering from Virginia Tech, focusing on the design of cellular manufacturing systems. She then joined the faculty of the University of Missouri, Columbia in the Industrial and Manufacturing Systems Department. After taking some time off to raise her children, she supplemented her education in the field of accounting and became the Senior Accountant of Glenn B. Cohen, CPA, an accounting and financial management firm. She has been an author of Engineering Economy since the publication of the 10th edition.?
Joseph Wilck is an analytics and operations faculty member at Bucknell University. Dr. Wilck received his PhD in Industrial Engineering and Operations Research from Pennsylvania State University, and an MS and BS in Industrial and Systems Engineering from Virginia Tech. He conducts research in applied optimization, data science, and analytics. Prior to joining Bucknell University, he was on faculty at William & Mary, United States Air Force Academy, East Carolina University, and the University of Tennessee.
