About Professor Gabriel Oladapo Adeyemi

MY BRIEF PROFILE

I have been a Professor of Environmental and Engineering Geology since 2007 at the University of Ibadan.

The tools for my research are:

  • Petrographic studies of rocks.
  • Mineralogical, geochemical and geotechnical studies of Lateritic Soils.
  • Surface geophysical surveys in generating subsurface models.
  • In-situ geotechnical investigations.

I have made substantial contributions to knowledge in the following areas:

  • Highway geotechnical studies.
  • Preconstruction investigations for buildings, roads and dams.
  • Environmental impact assessment of exploration and exploitation of tar sands.
  • Evaluation of naturally occurring construction materials.
  • Evaluation of probable waste disposal sites.
  • Mechanical and Chemical stabilization of lateritic soils.

My research activities have resulted in supervision of many Bachelors of Science and Masters of Science dissertations and 16 Doctor of Philosophy theses.

Although my main areas of research are Environmental and Engineering Geology, I have also supervised projects and theses in Hydrogeology, Environmental Petroleum Geology, Hydro Geophysics and Environmental Engineering Geology.

Prominent among the innovations in my researches are

  • The use of percentages by volume (instead of weight) of stabilizers for improving engineering properties of soils. This approach is easy to apply at sites.
  • Use of Lateritic soils of better geotechnical properties to stabilize other lateritic soils.
  • Use of termite reworked soils for stabilization of lateritic soils from both Basement Complex   and Sedimentary terrains of   Nigeria.
  • Incorporation of permeability determination in the evaluation of highway subgrade and sub-base soils.
  • Use of statistical methods to determine which of anthropogenic and geogenic factors has stronger influence on the chemical composition of shallow groundwater.

Administratively, I was Head of Department of Earth Sciences, Ogun State University, Acting Head of Geology Department and Director of General Studies, University of Ibadan.

I have taught and practiced Geotechnics and related disciplines for over forty years. Specifically, I have been preconstruction investigations for many buildings, flexible highway pavements and dams in Nigeria.

Professionally, I am a Fellow of the Nigeria Association for Engineering Geology and the Environment, a member of the Deep Foundations, Institute of the U.S.A, an affiliate member American association of civil engineers and an Associate Member of the Nigerian Society of Engineers.
