I help teams build imaging systems—from sensor to insight.

I help teams turn imaging concepts into testable camera prototypes—aligning system architecture, sensor integration, electronics, experiments, and graph-based data analysis around the decisions that matter.

Build the right camera system—not just the right component.

A successful imaging prototype depends on the full signal chain: the sensor, readout electronics, timing and synchronization, optics, calibration, data interfaces, and the algorithms that convert measurements into useful information. I connect these layers so hardware choices remain traceable to reconstruction quality and machine-vision performance.

Services

From Technical Challenge to Working System.

01

Camera System Architecture & Prototype Development

Translate application requirements into an end-to-end architecture, define interfaces and trade studies, plan integration, and drive a prototype from concept through bring-up and experimental validation.

02

Sensor Integration & Developer Collaboration

Work directly with CMOS and SPAD image-sensor designers to align sensor behavior, readout modes, timing, data formats, operating constraints, and prototype requirements. Characterization is focused on the measurements needed to make architecture and integration decisions.

03

PCB Design & Electronics Execution

Develop and coordinate schematics, component selection, PCB design, power and signal interfaces, design reviews, bring-up plans, and bench debugging for camera and sensor-support electronics.

04

Multimodal Data Analysis with GSP

Model measurements as signals on graphs to fuse heterogeneous modalities, reconstruct missing or sparse data, improve spatial resolution, suppress noise, and preserve meaningful boundaries using physical and contextual relationships.

05

Technical Program Leadership

Structure milestones, coordinate cross-functional contributors, manage technical risk, document decisions, and keep experiments and hardware development connected to a clear validation plan.

06

Experimental Support for Expert Witness Work

Help design, execute, and document controlled technical experiments that support independent expert analysis. Scope, methods, uncertainty, and results remain explicit and reproducible.

Johanna Garcia Cardona, PhD
About

I work at the point where image sensors become complete camera systems—and where complex measurements become defensible technical insight.

My background spans camera and instrument architecture, image-sensor integration, PCB and electronics development, prototype bring-up, experimental validation, and computational imaging. I work closely with image-sensor developers so the prototype architecture reflects how the sensor actually behaves—not only what a data sheet suggests.

01

From sensor behavior to system-level performance

Collaboration continues through interface definition, operating-mode selection, timing and synchronization, data acquisition, focused characterization, troubleshooting, and validation. I translate between sensor design, electrical implementation, system requirements, and downstream reconstruction so teams can make informed tradeoffs early.

02

Graph Signal Processing and multimodal analysis

My doctoral research at the University of Southern California applies GSP and graph learning to multimodal remote-sensing data. The same core ideas—using relationships, context, and physics to recover information from sparse, noisy, or mismatched measurements—extend naturally to SPAD, CMOS, depth, transient, spectral, and other multimodal camera systems.

03

Technical leadership and experimentation

I lead technical work by making interfaces, ownership, risks, and validation criteria explicit—while remaining hands-on with design reviews, PCB execution, bring-up, data analysis, and experimental planning. I also support controlled experiments for expert-witness engagements, with emphasis on reproducible methods, traceable assumptions, uncertainty, and clear documentation.

04

Entrepreneurial perspective

Through the NSF I-Corps National program, I developed practical experience in customer discovery and technology commercialization. That perspective helps me connect technical decisions to user needs, development risk, and a credible path from prototype to product.

WORKING STYLE — Collaborative, technically rigorous, and comfortable moving between architecture reviews, laboratory work, sensor teams, PCB development, project coordination, and quantitative analysis.
