Jonathan Lui, P.E.
SENIOR CONSULTANT
Jonathan Lui joined CGA in the spring of 2011 after working two years as a structural engineer with KPFF Consulting Engineers. While there, he had the opportunity to work on several commercial projects varying from complex steel frame hospitals to simple tenant improvement jobs. His consulting activities at CGA have focused upon vibration control, finite element modeling, and vibration measurements for high-technology facilities including semiconductor fabs and research laboratories as well as commercial structures such as parking garages.
Matt Sneddon
SENIOR CONSULTANT
Matt has forty years experience conducting a broad range of acoustics and vibration research, development, and consulting activities. Much of this work has been interdisciplinary in nature, involving acoustics, signal processing, materials science, and software development, with projects ranging from small consultations to large R&D initiatives. He is equally at home managing the activities of project teams, mentoring technical staff, and working “hands-on” in direct technical roles.
Formerly a Senior Scientist with BBN, he worked on or directed approximately 200 projects over a 23 year period, and more recently at ATS Consulting, addressing transportation noise and vibration problems. Recent activities include developing improved methods for modeling elastic wave propagation through soils, and characterizing the behavior of high transmission-loss acoustic metamaterials.

Lee Gorny, Ph. D.
CONSULTANT
Lee came to CGA in 2019 with seventeen years of experience in noise control engineering, acoustics and mechanical design. Here, he has focused on projects related to acoustical design and modeling, structural simulation using finite element analysis (FEA), and in measuring noise and vibration at industrial, commercial and high technology facilities. Prior to this, Lee worked at the National Institute of Standards and Technologies (NIST) developing a long-wavelength acoustical flowmeter (LWAF) and as an R&D engineer for SunPower Corporation, specializing in product design, simulation, integration and optimization.
Chin Leung
CONSULTANT
Chin joined Colin Gordon Associates in 2023 as a consultant with expertise in finite element modeling, specifically frequency, transient and random response of structures to dynamic loading, modal testing, non-metallic material modeling, as well as simulation and test data process automation. As a stress and dynamics analyst with over a decade of experience in prior roles spanning clean energy, aerospace and defense industries, Chin leverages a broad breadth of skillsets to optimize engineering analysis workflow throughput while maintaining accuracy, and helping to develop novel techniques to tackle complex engineering problems.

Cherie Allgood
ADMINISTRATIVE ASSISTANT
Decades of Experience
Colin Gordon Associates was formed in March 1990, and provides specialized consulting services in acoustics and vibration control. The firm has grown steadily from a one-person firm to a strong organization offering services world-wide. CGA has evolved to provide a variety of services ranging from sophisticated vibration and noise control to solutions of more mundane problems that may arise.
CGA is the world leader in the design of low-vibration and low-noise environments for technological buildings, but we work extensively in many other sectors as well. On many projects, the company serves as a member of the architect/engineer design team. On others, the company acts individually and directly with the owner. On yet others, CGA provides oversight support as a peer reviewer, owner’s representative, or via monitoring services.

Colin G. Gordon
FOUNDER
Colin Gordon (1934-2005) founded the firm that bears his name in 1990 and worked in the field of acoustics research and noise and vibration for over thirty-five years. Twenty years were spent with the firm of Bolt Beranek and Newman (BBN), the firm largely responsible for developing the engineering science of acoustics between 1950 and 1970. Five years were spent with the Institute of Sound and Vibration Research (ISVR) at the University of Southampton. In his last twenty years, the microelectronics industry was a key area of focus, with the design of low-vibration facilities for the research and fabrication of integrated circuit "chips". Colin developed a strong and unique reputation in this specialized field. Colin was widely recognized within the microelectronics industry for his contributions to the understanding of the vibration and noise environments of technology buildings. He pioneered many of the now-common analytical approaches to floor design and the analysis of noise and vibration from ducting and piping. He was co-developer (with Eric Ungar) of the widely-used vibration criteria for vibration-sensitive facilities. He had mentored many of the current generation of vibration consultants in this field.
