SUMMARY STATEMENT

I am a versatile and highly technical professional geoscientist with significant technical and project management experience in shallow subsurface geophysics, geotechnical engineering, construction observation and materials testing, environmental site assessment and karst hydrogeology. I strive to provide clients with enhanced site characterization, assessment and remediation strategies and site development recommendations based on value-oriented solutions including the use of geophysical survey or non-destructive testing data synthesized with intrusive testing and sampling data, monitoring installations, field geologic mapping and remote sensing methods to construct 1-D, 2-D, 3-D and 4-D site models and maps.

PROFESSIONAL EXPERIENCE

Senior Project Manager

Senior Geophysicist/Geologist

Environmental and Engineering Geophysical Services Manager

ECS Mid-Atlantic, LLC, Chantilly, VA 02/2008-09/2011

Primary responsibilities included building and managing a cohesive environmental and engineering geophysical services group for the Washington, D.C. metropolitan region. This role included the development and continual enhancement the geophysical capabilities of the Chantilly Office and other regional offices. This role involved the planning, conducting and managing a variety of 1-D, 2-D and 3-D field geophysical surveys including p-wave and surface wave (ReMi/MASW) seismic surveys, electrical resistivity surveys, ground penetrating radar (structure scan and ground scanning surveys, and electromagnetics surveys and crosshole sonic logging. The position also involved geophysical data reduction, processing, interpretation, QA/QC, geophysical report production and review and integration of geophysical studies with subsurface exploration geotechnical engineering analysis. In this role, I strived to practice with an emphasis of providing value-oriented solutions with a track record of saving clients significant environmental monitoring, environmental remediation, structural design, earthwork, foundation construction and vertical buililding construction costs on dozens of commercial, residential and public sector projects.

Position responsibilities also included the preparation and senior review of proposals and reports, geophysical and geosciences research, training, mentoring, direct supervision and task supervision of junior staff, evaluating, purchasing, and maintaining of geophysical equipment and vendor relationships and internal and external marketing of environmental and engineering geophysical services. Marketing vehicles included preparing and delivering formal oral presentations, attending client meetings, industry conferences and events and the preparation and distribution marketing materials to external clients and internal (ECS) staff. Management responsibilities included the direct supervision and mentoring of one full-time professional staff and supervision of several part-time technical staff. Additional responsibilities included developing and tracking budgets, preparing change orders, project billing, invoicing and collections.

Examples of engineering and environmental geophysical projects at ECS included:

1. Senior geophysicist and project manager for mapping and locating of underground storage tanks (USTs) and underground utility infrastructure via electromagnetics (EM) and ground penetrating radar (GPR) surveys;

2. Senior geophysicist and project manager for mapping top of weathered rock, competent rock, extent of alluvium within stream valleys, bedrock discontinuities and geologic contacts along linear alignments including roadways, bridge abutments, underground utilities and stream restorations using seismic refraction, ReMi, MASW and electrical resistivity methods. Integrated data from soil borings and rock cores to provide rippability and rock excavation assessments as required for design feasibility and cost estimating purposes.

3. Senior geophysicist and project manger for conducing rock studies in the Washington, DC metropolitan area for proposed underground construction including parking garages and basements using pseudo 3-D seismic refraction and ReMi studies. These studies involved construction of 3-D wireframe maps and rock contour maps from a series of tightly-spaced geophysical profiles within the proposed limits of construction and integrating information from soil borings and proposed lowest floor levels to develop highly-refined volume estimates of rock materials required for removal based on various design scenarios for cost estimating purposes. Information from these studies likely saved multiple clients six figures in cost and months of project development time.

4. Senior geophysicist and project manager for 2-D and 3-D mapping of the extent, character and thickness of landfills and contaminated soils through the use of electrical resistivity profiles correlated to intrusive sampling data. Data from 3-D surveys were and integrated into wireframe and contour maps and used for volume analysis.

5. Senior geophysicist and project manager integrated geophysical studies via seismic refraction, electromagnetics (EM-31/EM-38), GPR and ER methods to map spatial and time-lapse variations in the water table and moisture content for agricultural studies at vineyard sites in northern Virginia;

6. Senior geophysicist and project manager for karst geotechnical and risk assessment studies including the mapping buried faults, geologic contacts, sinkholes, voids, solution cavities, groundwater pathways, depth to rock, variations in rock quality, formational contacts, stratigraphic discontinuities, structural lineaments and problem/soft soils using ER and geotechnical borings within Culpepper Basin of Northern Virginia.

7. Senior geophysicist and project manager for Site-specific seismic studies and seismic risk assessments for dozens of sites in the Washington DC Metropolitan area via integration of shear wave seismic data and soil profile data from soil borings and probabilistic seismic hazard analysis (PSHA) as per the international Building Code (IBC) 2000/20006/2009;

8. Senior geophysicist and project manager and technical lead for crosshole sonic logging (CSL) services for multiple public sector transportation infrastructure projects in the Washington, DC Metro area including Silver Spring (Maryland) Transit Center and Fort Belvoir North and South Loop roads and bridges.

While at GeoConcepts, I managed and completed dozens of small to large-scale geophysical studies supporting environmental and engineering projects for the purposes of well sitting and hydrology, karst risk assessment, geotechnical engineering feasibility, design and remediation, locating and mapping buried structures including USTs, foundation elements, underground utility infrastructure, and tree roots and mapping depth to rock and formational contacts.

Sr. Staff Geologist/Geophysicist

URS Corporation, Gaithersburg, MD 01/2000 - 09/2005

Primary responsibilities included planning and conducting numerous geophysical surveys, including surface geophysical surveys and vibration monitoring arrays and subsurface investigations for environmental, geotechnical engineering design and construction phase projects. Duties included assisting in task and project management tasks on numerous small to large-scale environmental and engineering geophysical and geotechnical engineering projects, serving as a geophysical field team leader and project technical lead while gaining significant experience in the preparation of geophysical, geotechnical engineering and environmental engineering reports, proposals, cost estimates and work plans. Responsibilities included the preparation of environmental and geotechnical boring logs, environmental sampling reports and related tables and graphs for principal review by registered professionals.

The scope of these projects included groundwater supply studies, geologic mapping, environmental site assessment and monitoring, geotechnical engineering design and construction, mapping of underground utilities and structures and remedial engineering studies.

Some of these bathymetric studies were conducted simultaneously with marine ERI surveys to map the thickness of sediment layers, depth to bedrock and/or karst issues. ERI data were compared to existing intrusive data including soil borings and sediment cores. In addition, I participated on several earthen dam and reservoir construction and remediation projects using geophysical data from seismic refraction and ERI surveys correlated to soil borings and in-situ testing data to assist engineers in the design and/or remediation of earthen dams and impounding reservoirs.
