Martin Vulaj is the Chief Executive Officer of Overwatch Grid Systems, where he leads the company's mission to deploy advanced sensor networks and AI-powered analytics for environmental, infrastructure, and security monitoring.

A seasoned entrepreneur, Martin has built and scaled multiple companies across diverse industries. He grew a construction services firm to more than 60 employees and a marine environmental remediation company to over 400 employees, demonstrating his ability to drive growth, manage complex operations, and deliver sustainable results. At Overwatch, he leverages this experience to build high-performance teams, foster strategic partnerships, and bring transformative technologies to market.

Earlier in his career, Martin held leadership roles in international policy and diplomacy, including serving as Executive Director of the National Albanian American Council in Washington, D.C. In that role, he worked with the U.S. Department of State, the White House, and Congress on issues of democracy, security, and development in Southeast Europe.

Martin earned his Juris Doctorate from Albany Law School and graduated Cum Laude in Philosophy from Fairleigh Dickinson University.

Lawrence Kahn is a Professor at Tulane University, attorney, entrepreneur and educator who has provided advisory services in the environmental and maritime "trees and seas" space for over 25 years. He is a Distinguished Research Fellow with the Tulane Center for Environmental Law.

Mr. Kahn previously worked for the U.S. Army, where he was certified as a Contracting Officer's Representative and negotiated and enforced government contracts and had oversight of the hazard tree removal program, management of Army timber, flora and fauna resources.

Kahn developed (and currently serves as Director of) the Tulane Utility Vegetation Management Initiative ("UVMI"), a joint project of Tulane Law School's Center for Environmental Law and Tulane Law School's Center for Energy Law.

The UVMI is now widely recognized as the leading neutral academic center of its area of focus and it has attracted positive attention from government, non-governmental organizations, the utility industry, and a variety of private and public companies.

Guillaume Riviere is the Chief Technology Officer of Overwatch Grid Systems, where he leads the architecture and development of the company's edge-AI sensor platform — from the solar-powered field hardware up through the cloud intelligence layer that turns raw signal into real-time situational awareness.

He is the architect of the Overwatch platform: a distributed mesh of multi-modal sensor nodes (LiDAR, thermal and optical imaging, environmental and acoustic sensors) backed by an on-device decision engine that runs computer-vision and ML inference at the edge, and a cloud stack that fuses, classifies, and acts on those detections in seconds. His work spans embedded Linux, low-power computer vision, model deployment to constrained devices, secure mesh networking, and the data infrastructure that ties it all together.

Over 20+ years, Guillaume has built and shipped technology for Fortune 500 companies across automotive, gaming, civil engineering and construction — with a long-standing focus on real-time systems, mixed reality, and the intersection of hardware and software. A multi-disciplinary, multicultural engineering leader, he specializes in remote team organization and operational delivery, and brings that same hands-on, builder mindset to Overwatch.

Stephen Cieslewicz, a U.S. Navy veteran, is one of the most recognized leaders in the utility vegetation management (UVM) industry, with four decades of experience advancing technology, regulation, and practice.

He began his 40 year career at Pacific Gas & Electric as its first ISA-certified arborist and System Utility Arborist. He later co-founded CN Utility Consulting (now EOCENE), serving as president for 17 years. A pioneer in utility technology, Stephen drove the adoption of LiDAR, UAS, satellites, remote sensing, and AI-driven inventory and work management systems, reshaping how utilities monitor risk, manage vegetation, and protect infrastructure. His work also extends to wildlife habitat monitoring, pollinator protection, and environmental applications.

Stephen helped craft key regulations and standards, including NERC FAC-003 and California's GO 95 Rule 35, and has consulted with utilities across three continents, serving as an expert witness in more than 40 cases.

His contributions have earned broad recognition: a Certificate of Appreciation from the U.S. and Canadian governments for co-leading the 2003 Northeast Blackout UVM investigation (commissioned by FERC); recognition in 2011 by Green Media as one of the eight most influential people in the green industry; and a 2022 UAA Award honoring The UVM Podcast, which he co-hosts with Nick Ferguson, for advancing industry education and innovation.

Today, Stephen continues to consult with utilities, regulators, and technology developers, while using The UVM Podcast to connect the industry with emerging tools and ideas that define the future of resilience.
