Our Team

An organization is only as good as its team. At Global Systems Engineering, we pride ourselves on  experienced leadership team with broad expertise across the Federal Enterprise, supported by a team of cross-cutting personnel from military, STEM, and policy backgrounds that bridge the gap between decision makers, technologists, and operators.


Christopher Russell

Managing Partner

Chris has over 20 years of experience in engineering, design, implementation and sustainment of complex systems and systems of systems. He has extensive experience both as a federal civilian and as a contractor on programs across the Federal CWMD Enterprise, particularly within DOD, DHS and other Federal Response and Recovery Developers.
