Research description

My recent research involves evaluating the performance of a variety of infrastructure projects that include highway embankments, riverbanks, hydroelectric facilities, and underground nuclear waste disposal repositories. It has developed from projects funded by various public agencies and private sectors. Recent research projects include: adaptive design for climate-resilient northern infrastructure, riverbank stabilization using rockfill columns, performance of clay seals in underground nuclear fuel waste repositories, mobilization of frost heave forces on pile foundations, and stabilization of soft clays using cement, slag and nano-silica. These projects involved a combination of two and sometimes three of the following research components: 1) conventional and large-scale laboratory tests, 2) full-scale field tests, and 3) numerical modeling. The research has advanced current design and construction practices by providing modeling and analysis recommendations that help engineers predict and mitigate excessive deformations and instabilities of earth structures and foundations.

Biography

Dr. Marolo Alfaro is a professor in the Department of Civil Engineering at the University of Manitoba, Canada. He received a BSc in civil engineering (magna cum laude) from the University of Mindanao, Philippines, an MEng in geotechnical engineering from the Asian Institute of Technology, Thailand, and a PhD in civil engineering from Saga University, Japan. He received postdoctoral fellowships from the Royal Military College of Canada and the University of Calgary in Canada.
Marolo has published widely in technical journals and in conference proceedings, receiving awards for his research work. He received the 2019 Geosynthetics Award given by the in recognition of outstanding contribution to the applications of geosynthetics in civil, geotechnical and geoenvironmental engineering in Canada and internationally. Marolo is the leader of a University of Manitoba research team that received the 2022 Roger J.E. Brown Award given by the Canadian Geotechnical Society in recognition of outstanding contribution to permafrost engineering. He has co-authored a book and a book chapter.
Marolo is a registered Professional Engineer with Engineers Geoscientists Manitoba specializing in geotechnical engineering. He worked as an engineering consultant on a broad variety of infrastructure projects. He has just been appointed as Chair of the Canadian Geotechnical Research Board (GRB) for 2022-2025. The mandate of the GRB is to monitor, stimulate, and promote research in the geotechnical engineering and geoscience fields for the benefit of the profession and Canada. He served as Vice-President of the International Geosynthetics Society - North American Chapter, Member of the Executive Board of the Canadian Geotechnical Society, and Canadian representative to the Committee on Ground Improvement of the International Society of Soil Mechanics and Geotechnical Engineering. He is a member of the Canadian Society for Civil Engineering and the American Society of Civil Engineers, and International Society of Soil Mechanics and Geotechnical Engineering. Dr. Alfaro is an Associate Editor of Frontiers in Built Environment Journal.
