Experience

Principal Geological Engineer, Childs Geotech LLC

2025 - Current
Tucson, Arizona, USA

Highly experienced Principal Geological Engineer with more than a decade of proven success consulting on complex mine slope stability challenges. Proven expertise in geotechnical investigations, slope stability analysis, and risk assessment for open-pit mining operations.

Currently developing innovative slope stability software that leverages AI and machine learning to improve the accuracy and efficiency of stability assessments.

Lead Geological Engineer, Call & Nicholas, Inc.

2018 - 2025
Tucson, Arizona, USA

Developed an innovative method using advanced artificial intelligence algorithms for analyzing borehole televiewer data to identify rock fracture orientation trends. This method enhances slope stability analysis by automating the clustering of similar fracture orientations, overcoming the limitations of traditional manual methods that are subjective and time-consuming. It provides a reproducible and efficient approach to characterizing rock fabric.

Developed DronePlan3D, a custom flight planning software for drones, to enhance geologic data collection in open-pit mines. This innovation overcame limitations of existing solutions by maintaining a constant ground sampling distance across varying topographies, thus ensuring consistent point cloud resolution and capturing geologic structures on vertical bench faces effectively. The solution provided significant value to mines by delivering high-resolution and accurate point clouds that can be utilized for remote geotechnical structure mapping and long-term slope movement monitoring.

Staff Geological Engineer, Call & Nicholas, Inc.

2013 - 2018
Tucson, Arizona, USA

Geotechnical consultant for rock mechanics, slope management, and slope stability evaluations for operating properties and feasibility level studies in the international mining industry.

Responsibilities include geotechnical monitoring, site investigations, rock-mass and strength characterization, slope stability analysis, and report preparation. Areas of specialization include probabilistic and limit-equilibrium slope stability models.

Geotechnical Engineer, KGHM International, Robinson Project

2012 - 2013
Ely, Nevada, USA
On-site geotechnical engineer focusing on slope monitoring, project management, and stability analysis. Managed multiple geotechnical drill programs. Installed and monitored various slope stability programs to predict and prevent slope instabilities. Experience with Robotic Total Stations, Slope Stability Radar, Time Domain Reflectometers, and LIDAR. Performed multiple back-analyses of previous slope failures and instabilities to determine geotechnical parameters of various geotechnical domains. Recommended slope angles using two-dimensional limit equilibrium models. Recommended safe operational designs to mitigate rockfall hazards. Maintained a positive relationship between the technical services group and operations group to accomplish mutually beneficial goals.
