T. Russell Gentry

Associate Professor and Coordinator of M.S. and Ph.D. programs, School of Architecture

Associate Director for Research, Digital Fabrication Lab (AWPL)

Phone: (404) 894-3845Office location: 247 4th Street

Russell Gentry is an Associate Professor of Architecture with a courtesy appointment in the School of Civil and Environmental Engineering. He teaches courses in building structures and materials, fabrication technologies, and design and construction process. He is the faculty mentor for the 2013 class of the Georgia Tech Presidential Scholars.

Professor Gentry pursues research that fall into three broad themes:

  1. Developing and assessing new load bearing materials and systems
  2. Embedding structural and fabrication logic into CAD and simulation tools
  3. Quantifying embodied and ongoing energy impacts of buildings – and use of these metrics in the design process

His current work in the materials area focuses on the development of high-modulus FRP reinforcements for use in strengthening juvenile pine laminated timbers.  His work in the structural systems area is focused on concrete masonry, jointly with Tristan Al-Haddad and Andres Cavieres.  He recently completed project (with Charlene Bayer of the Georgia Tech Research Institute and Michael Gamble) examining the future of Life Cycle Assessment in architectural practice.

Research Groups/Labs

Dr. Gentry is the former Associate Director of Research in the Advanced Wood Products Laboratory and is currently a faculty leader in the College of Architecture’s Digital Fabrication Laboratory.

Brian Bowen

Professor of the Practice, School of Building Construction

Phone: (404) 894-3880Office location: 500 Tenth Street NW

Professor Brian Bowen was appointed the College of Architecture’s first professor of practice in 2007. Prior to this since 2000, he supported the College’s Continuing Education Program with specific focus on courses in Managing A & E Practices and Contracting Companies. He retired in 2000 as president of Hanscomb Inc., an international construction consulting company active worldwide in managing construction projects and programs. He was trained in England as a quantity surveyor joining Hanscomb in 1960 in London, moving to Montreal in 1961 and then Atlanta in 1982.

Current research is directed in three main quarters:
1.    Knowing how the American construction industry evolved from colonial times for the purpose of understanding its current structures, organization, processes and methods used to deliver its projects.
2.    Studying the current industry in order to devise improvements in productivity and in value delivered to its clients.
