• Developed the first ¹⁰Be geochronology and detailed glacial geomorphic map used for reconstruction of past climate in Chirripó National Park (CNP), Costa Rica• Utilized ¹⁰Be surface exposure ages to determine the extents of glaciers and rate of ice retreat during and after the LGM in CNP. • Compared the timing of glacier extent and retreat across the tropics.• Conducted fieldwork and collected samples for cosmogenic ¹⁰Be and ³He surface exposure dating• Used MATLAB for statistical analysis, data visualization, and testing hypotheses.• Presented the preliminary results of my research at reputable international conferences (INQUA, Rome and AGU, San Francisco).

• Reviewed geological and geophysical reports from the Nigeria Geological Survey Agency (NGSA) to develop exploration projects within south western Nigeria which produces over 200ppm concentration of gold. • Analyzed and interpreted satellite image and geochemical data using ArcGIS to identify geological structures and estimate gold deposits within south west and northwest of Nigeria. • Colleced and classified rock samples to facilitate mineral exploration projects.• Evaluated subsurface field and sampling data to recommend geologic sites for mineral exploration. • Created 30+ geologic and topographic maps for technical reports and exploration development within Northern and Western Nigeria.

As a Science subjectTeacher, 1. Prepared final year secondary school students on various geographical topics like soil profile and weathering for external exams such as WAEC and JAMB.2. Developed lesson notes that aligned with the guidelines of the Nigeria government approved curriculum.3. Organised chemistry laboratory sessions for secondary school students.4. Evaluated and graded students' class work and assignments

Achievements and responsibilities • Tested soil and designed stabilization systems to ensure stability of structures on unstable soil.• Performed geotechnical studies of foundation of buildings (50), culverts and bridges (10), and routes (60km) that include parameters calculation and reports preparation.• Determined availability, strength and viability of soil materials for construction projects. • Calculated load levels and material stress factors using DS 7.1 suite to identify design constraints.• Computed load and grade requirements, material stress factors and water flow rates to determine design specifications.• Prepared and maintained accurate and complete work records and reports using Microsoft Office Suites.• Displayed strong communication and interpersonal skills while visiting clients, jobsites and consultant offices to support project and business development needs

Here at EarthProbe Nigeria Limited, I was able to achieve the following:• Utilized Stratabug and the Excel suite for data extraction, production, and analyses especially for biostratigraphy data representation which I used for Sequence stratigraphic interpretation. • Interpreted, correlated, and performed petrophysical analyses on well logs with the assistance of oil professionals. • Led the collection and sampling of cores and ditch cuttings to identify and interpret depositional features• Engaged in Well-site Biostratigraphy analysis.• Carried out detail Well-log Sequence Stratigraphy analysis utilizing high resolution biostratigraphy majorly within the Niger Delta Basin and Dahomey Basin.In addition, I was also partly responsible for the laboratory preparation of microfossils slides for biostratigraphic analysis, and Identification of microfossils using microscope and used them in paleoenvironment reconstruction.
