Research Overview

My research interests and efforts are centered in Process Improvement Theory and its application in the fields of healthcare and construction. In healthcare, introducing modern strategies for quality management, and performance and process improvement at different levels (e.g. hospitals to state agencies), to ensure quality of healthcare delivery, improved health outcomes and patient safety. In construction, exploring and introducing advanced homebuilding production technologies into industry and improving homes’ energy performance. This has led to sponsorships from the department of Housing and Urban Development (HUD), Department of Energy (DOE), Louisiana Department of Health and Hospitals (DHH), W.M. Keck Foundation and private industries. I am a certified Master Black Belt and an active member of the Institute of Industrial and System Engineering (IISE), and Society for Health Systems (SHS).

Recent Projects

  • Partnership to Prepare Industrial Engineering Undergraduates for Healthcare Careers (W.M. Keck Foundation, current)
    • This project will expand IE students’ knowledge and career options via a healthcare certificate composed of one new healthcare course, one seminar course, two capstone courses with a healthcare project, and an internship in a healthcare business. A Healthcare Industry Advisory Board (HIAB) will play a prominent role in guiding the initiative.
    • IE Research Graduate- Healthcare opportunity 
  • U2 KneeTMSystem with a Disposable Trial: Cost and Efficiency Study (United Orthopedic Corporation, completed April 2017)
    • This study compares cost and efficiency of using two different technologies (disposable versus traditional trials) used during total knee replacement (TKR) surgeries.
  • Organization Performance Excellence: Performance Measurement and Improvement in the Department of Health and Hospitals (Louisiana DHH, completed June 2015)
    • The goals of this project were to develop a performance metrics dashboard for DHH and four of the office within DHH, to streamline business planning documents, and to conduct process improvement projects within each office.
