Merline is responsible for conducting scientific research to provide mining and mineral exploration companies, and relevant licensing and governance bodies operating in Labrador, with key technical information that can ultimately lead toward the opening of new mineral mining operations. Her research projects mainly target various mineral deposits in Labrador (Iron ores, REE, U, Ni-Cu Sulfide), using both field- and laboratory- based investigations. She is also undertaking projects related to environmental impacts of mining and other human activities.
Merline is also an adjunct faculty member with Department of Earth Sciences at Memorial University and supervises/co-supervises graduate and undergraduate students. She is a registered professional geoscientist with the Association of Professional Engineers and Geoscientists of Newfoundland and Labrador.
B.Sc. in Earth Sciences (1997), University of Yaoundé I (Cameroon).
M.Sc. (1999), University of Yaoundé I.
My thesis project focused on volcanology and petrography of basaltic lavas and basement rocks from Mangoum Area, southern continental part of the Cameroon Volcanic Line, Central Africa.
Postgraduate diploma, DEA (2000) in Petrology-Volcanology, University of Yaoundé I.
My research project was a review and comparison between oceanic and continental alkaline volcanism along the Cameroon Volcanic Line, Central Africa.
Ph.D. in Geology and Igneous Petrology (2005), University of Würzburg (Germany).
My dissertation focused on bedrock mapping, geochemistry, geochronology and mineralization potential of the Pan African granitoids, within the Central Africa Fold Belt in the Bafoussam area, Western Cameroon.

Prior to joining the Labrador Institute, Merline worked at Queen’s Facility for Isotope Research (QFIR), Department of Geological Sciences of Queen’s University as Postdoctoral fellow (2006-2010) in the field of Geochemistry applied to mineral exploration and environmental monitory and at Kingston Process Metallurgy Inc. (KPM), a consulting company providing Research and Development services to mining, metallurgical and chemical industries, specializing in Applied and Process Mineralogy for two years.
Merline is equally passionate about things outside the world of geosciences, including indoor and outdoor activities, fine cuisine, home decor, and most importantly music and dance.
