Profile

I am a keen and highly motivated young geologist with extensive training from both academic and industry environments. Throughout my university and industry years, I have focused on courses and research topics pertaining to ore geology, structural geology, geochemistry, mineralogy and geological mapping techniques.

In June 2016, I graduated the Masters program 'Evaluation of Sedimentary Basins and Mineral Resources' from the Faculty of Geology and Geophysics at the University of Bucharest. During the Masters project, I had the opportunity to work in collaboration with the Exploration department of the Boliden Mineral A.B. mining company on the Petiknäs North VMS deposit in Northern Sweden. 

I also have industry experience, having worked as a project geologist doing geological mapping for a company that is providing geological studies for large infrastructure projects and in the mining industry, and as an exploration geologist for Porphyry Copper deposits in SW Romania.

I came to Leeds in October 2017 for my PhD program. Whilst here, I aim to broaden my knowledge in structural geology, geochemistry and ore deposits and I will try to understand the feedback relationships between the structural featrues and the geochemical changes associated with fluid transport in orogenic gold deposits.

Current Research Project

Title: Structural and geochemical differences in orogenic gold mineralization from the Newfoundland Appalachians and Irish Caledonides, and wider implications for orogenic gold models and exploration strategies

Funding scheme: Leeds Doctoral Scholarship

Research Grants

  • Society of Economic Geologists (SEG) –  Student Research Grant funded by Newmont Mining Corporation (2019)
  • Geological Society of London – Annie Greenly Fund (2019)
  • Geological Survey of Northern Ireland (GSNI) (2018, 2019)
  • The Institute of Materials, Minerals and Mining (IOM3) – G Vernon Hobson Bequest Grant (2018, 2019)
  • Geologists' Association - NewResearch Grant Scheme (2018)
  • The Applied Mineralogy Group (AMG) of the Mineralogical Society of Great Britain and Ireland – Postgraduate Student Bursary Award (2018)

Summary: The project comprises both regional and deposit-scale structural and geochemical studies of gold occurrences from the Appalachian-Caledonian orogenic trend. The targeted occurrences are located along a major crustal-scale shear zone, the Baie Verte Line (Newfoundland) and it's subsidiary substructures, together with it’s orogenic counterpart in Ireland: the Fair Head-Clew Bay Line.

Aims: 

  1. establish the structural evolution history of the BVL/FCL and of their subsidiary structures in relation to the formation and the localization of orogenic gold mineralization;
  2. investigate the differences between the individual deposits, both in terms of their structural setting and their vein/fluid geochemistry;
  3. generate a general structural and geochemical framework through which to investigate the distribution of the orogenic gold mineralization in the Baie Verte Peninsula of Newfoundland and Western Ireland.
