Dr. Gress has a PhD degree from Purdue University in Civil Engineering with emphasis in Materials. He conducts experimental and analytical research on topics related to transportation materials, including the reuse of waste materials produced as byproducts of industry and when renewing the civil infrastructure. He has been involved with more than $14,000,000 in projects funded from a variety of federal agencies (e.g., Department of the Army, Department of the Navy, National Science Foundation, Environmental Protection Agency, Department of Transportation Federal Highway Administration, Department of Transportation Federal Aviation Administration, various State Agencies (e.g., Connecticut Department of Transportation, Maine Department of Transportation, Massachusetts Highway Department, New Hampshire Department of Transportation, Rhode Island Department of Transportation and Vermont Highway Department), and corporations (e.g., Public Service of New Hampshire and Wheelabrator Technologies). These research projects have included laboratory studies, full scale field experiments and demonstrations. Dr. Gress has published in referred journals (ASTM, ACI, TRB, MRS, ASCE) and various conference proceedings. He is Associate Director of the RMRC, and a licensed professional engineer in New Hampshire. Dr. Gress is a member of Transportation Research Board (TRB), American Concrete Institute (ACI), American Society of Civil Engineers (ASCE), American Society of Testing and Materials (ASTM), and the American Ceramic Society (ASC). He has been a reviewer for the DOE Waste Management Program, National Science Foundation, NY State Solid Waste Combustion Institute, and the Transportation Research Board. He is a member of the Policy Committee of the University Transportation Center (MIT, Harvard and all New England State Universities), Advisory Committee of the New England Transportation Consortium (all New England State Schools) and is a member of National committees: ACI 555 Concrete with Recycled Materials, TRB AFN10 Basic Research Emerging Technologies Related to Concrete, TRB AFN30 Durability of Concrete and ASCE Highway Research.

Teaching Interests

Engineering materials, pavement design, highway and airport design


Dr. Gress has taught civil engineering courses at the University of New Hampshire since the fall of 1974. He was the chair of the department for nine years from 1984 through 1994. He was on sabbatical during 1994 at the Federal Highway Turner Fairbanks Research Facility at McLean Virginia where he did research on the freezing mechanism of portland cement paste. He has been actively involved in research for over twenty years in the areas of basic materials research.

Research Overview

Civil engineering materials with emphasis on portland cement concrete, alkali silica reaction, concrete recycling, waste stabilization, byproduct recycling, bottom ash and other wastes for use as an aggregate substitute in civil construction.
