Autobiography

Prof Grace Ofori-Sarpong is a Professor of Minerals Engineering, and currently the Dean of School of Postgraduate Studies at the University of Mines and Technology (UMaT), Tarkwa, Ghana. Her previous positions held in UMaT include Acting Pro Vice Chancellor, Dean of Faculty of Mineral Resources Technology, Vice Dean of Planning and Quality Assurance Unit, Head of Petroleum Engineering Department, Head of Environmental and Safety Engineering Department, and Coordinator of University Examinations. Grace serves as a member on several national boards including the Governing Boards of the Minerals Income Investment Fund (MIIF), Ghana Chamber of Mines (GCM) Tertiary Education Fund, and University of Mines and Technology. She is also the Chairperson of the International Advisory Board of African Centre for Mineral Exploration and Development (ACMED) in AUST, Nigeria, and a member of the Amira Research Consortium. In addition, she serves/has served on the Governing Board of Academic City College, and numerous national and international committees including the Ministerial Committee of Enquiry on Health and Safety in the Mining Industry, the Publication Committee of Ghana Academy of Arts and Sciences, the Technical Committees of MIIF Board and GCM Council, the Committee of Independent Reviewers for International PhD Scholarship, Selection Committee of OWSD Early Career Fellowship and as Associate Editor of Journal of Sustainable Metallurgy. She has also served as organiser, keynote speaker, resource person and moderator for several conferences, workshops and seminars both locally and internationally.

Grace is actively involved in research and consultancy in the areas of precious minerals beneficiation, comminution characteristics, aqueous processing, mine waste treatment, acid mine drainage issues, and myco-hydrometallurgy, among others, and she has over 90 technical publications to her credit. With about 20 years’ experience in lecturing and research in minerals-related issues and community service, Grace has made a lot of strides including receiving an international award in 2017 from OWSD-Elsevier Foundation for her contribution in science and her positive role in inspiring and mentoring females to reduce the gender gap in STEM. Grace is the Founder and President of Ladies in Mining and Allied Professions in Ghana (LiMAP-Gh), a Fellow of the Ghana Academy of Arts and Sciences (GAAS), and West African Institute of Mining, Metallurgy and Petroleum (WAIMM).
