Current – ASU

I am the director of the Edifice Lab. Go to for the latest. The mission of Edifice Lab is to automate the creation of immersive digital learning experiences for the builders and stewards of infrastructure. We accomplish this by developing computer vision technologies for digitizing and abstracting the built environment.

Digitization and Abstraction of the Built Environment

Computer vision is the subfield of artificial intelligence that trains computers to interpret visual data. In the context of construction, it is used to automatically monitor safety and security, evaluate efficiency, track progress, detect defects, guide robotic systems, and support remote presence of scarce expert resources. At the Edifice Lab, we explore the sensors used to collect visual data, the tools used to fuse data into unified digital representations, and the algorithms available to automatically analyze these representations to extract useful insights for improving construction operations.

Past – UTexas

During my PhD, I worked on a collaborative project called:

Living Building Information Model (BIM): A Layered Approach for Automatic and Continuous Built Environment Model Update

You can read the abstract on the National Science Foundation website.

The project aims to improve the information practices of people who operate, maintain, and renovate facilities.

Building Life-Cycle


Specifically, by applying tools found in machine learning and computer vision, we made Building Information Models easier to update throughout the life-cycle of a facility.

Artificial neural network semantically segmenting images of building interiors

We are in the process of releasing an RGB-D dataset of building facilities for semantic segmentation research – 3DFacilities.

Samples from 3DFacilities

Past – UWaterloo

Team from the University of Waterloo

My master’s degree was focused on developing automated quality control tools for industrial construction, specifically pipe spool fabrication.

By analyzing point clouds captured by laser scanners, we could identify geometrical fabrication errors and mitigate the risk of on-site rework.
