ATA Management

Most of ATA’s senior management team have worked together since the late 1970s. They are widely known in the structural dynamics field as industry leaders in the application of test and analysis to develop successful designs for aerospace and other highly engineered structures.


Mary Baker, Ph.D., P.E.

Dr. Baker's expertise is in application of computer methods to structural dynamics and continuum mechanics with particular experience in liquid rocket development, satellite system engineering, launch vehicle and road vehicle dynamics, and simulation and testing of electronic equipment and consumer products for shock and vibration environments.

Dr. Baker brings more than 35 years of experience in project engineering to the ATA team. Prior to formation of ATA, Mary served as Vice President and General Manager of SDRC's Advanced Test and Analysis Division and guided this group for most of its 24-year history.

Significant projects include dynamic analysis, testing, and design during the development of an upper stage engine with an extendible nozzle; modeling and simulation of many aspects of liquid rocket components including turbo-pump thermal and vibration issues; design of communications shelters for mobility and transport; integration of multidisciplinary simulations tools particularly for spacecraft; and mechanical engineering of medical products.

Dr. Baker earned her Ph.D. and M.S. in Applied Mechanics from the California Institute of Technology, and in 2014 she was named one of Caltech’s Distinguished Alumni for her pioneering entrepreneurship and leadership in aerospace. She received her B.S. from the University of Wisconsin in Engineering Mechanics. She is a licensed professional engineer in the state of California.


Paul BlellochPaul A. Blelloch, Ph.D.
Vice President, Aerospace Analysis

Dr. Blelloch’s technical expertise is in the analysis of complex dynamic systems, particularly in the areas of control-structure interaction, optimization, model reduction, dynamic loads, model updating, and vibro-acoustics. He has written over 30 technical papers. As well as managing and performing a large variety of projects for various NASA centers and both large and small aerospace companies, Dr. Blelloch has developed advanced methods for analysis of control-structure interaction problems, model reduction of dynamic systems, damping of coupled systems, non-linear dynamic response, fluid slosh, pressure stiffening of tanks, rapid payload reanalysis, sensor selection for modal testing, model updating and development of launch vehicle buffet loads. He has also developed classes in structural dynamics and vibro-acoustics that he has taught at many NASA centers and aerospace companies.

Paul received his M.S. and Ph.D. in Mechanical Engineering from the University of California, Los Angeles. He received his B.S. in Mechanical Engineering from the Massachusetts Institute of Technology.


H. Clark Briggs, Ph.D.
Vice President, Aerospace & Defense Business Development

Dr. Briggs joined ATA in 2009 after retiring from NASA’s Jet Propulsion Laboratory (JPL) where he was a Member of the Technical Staff for over 20 years, serving in various roles in support of program management; systems modeling and analysis; mechanical software tool selection & implementation; and requirements management. At ATA, Clark’s efforts are focused on several areas including multi-disciplinary engineering modeling & analysis with applications to a variety of complex aerospace structures and thermo-optical-electro-mechanical systems; and the planning & implementation of Siemens NX and Teamcenter in aerospace companies.

Dr. Briggs received his B.S. degree from the U. S. Air Force Academy, and his M.S. and D.E.Sc. degrees from Columbia University. He also holds an M.B.A. from the University of Utah.


Ralph D. Brillhart
Vice President, Test

Mr. Brillhart brings over 30 years of testing experience to ATA. His previous experience with SDRC includes project management in Testing Services, performing a wide variety of dynamic and static durability and qualification testing of structures. Just prior to the formation of ATA, Ralph was Director of Test Projects for SDRC’s Western Regional Operation where he helped transform a small troubleshooting test group into the leading independent modal test organization. He has become recognized worldwide for his modal testing expertise and has helped innovate many new methods implementing current computer technology. He has served as a member of the executive board of the Society of Experimental Mechanics and the International Modal Analysis Conference (IMAC) Advisory Board.

Ralph received his M.S. in Mechanical Engineering, Dynamics and Control, from the University of California, Davis, and his B.S. in Mechanical Engineering from the University of Cincinnati.


Chris Kubik
Vice President, Eastern Region Operations

Mr. Kubik's expertise is in the application of computer methods to resolve the design problems induced by static and dynamic loads on automotive and aerospace structures. In addition, Mr. Kubik has considerable expertise in the organizational and technical aspects of process re-engineering developed through his five years assisting Ford Motor Company implementing a new product development process facilitated by the I-deas CAD/CAM/CAE and Metaphase PDM software products. He is currently responsible for bringing ATA Engineering technology, services and solutions to customers located in the Eastern United States.

Chris brings over 35 years of engineering and management expertise including 23 years with SDRC and EDS PLM Solutions. During his tenure at SDRC, Chris held numerous positions of responsibility including Manager of the Automotive Advanced Test and Analysis business in Detroit, Michigan. He was also the first Operations Manager of ESTECH Corporation, an SDRC and Nissan joint venture headquartered in Yokohama Japan which was created to provide engineering services to Japanese automotive and aerospace industries. In these and in other management capacities he was responsible for the organizations' financial performance, hiring, staffing and technical project management.

Mr. Kubik earned his M.S. and B.S. in Civil Engineering from the University of Akron and earned an M.B.A. from Xavier University.


Tom Deiters, P.E.
Vice President, Design/Analysis

Mr. Deiters has over twenty years of consulting experience in applying computer-aided engineering techniques and structural testing to develop and enhance designs in many different industries. Mr. Deiters has had broad exposure to all of ATA’s primary capabilities, including structural design, testing, and analysis. He spent ten years in ATA’s testing group acquiring key knowledge related to modal and strain testing for complex structures. Afterward, Mr. Deiters transferred to ATA’s design/analysis group, where he has managed the engineering staff and provided technical guidance for over ten years. His primary technical expertise centers on durability assessment of dynamically loaded metallic structures.

Mr. Deiters is a registered Professional Engineer in California. He received both his B.S. and M.S. in Mechanical Engineering from Purdue University. Afterwards, Mr. Deiters immediately started working at ATA Engineering (SDRC at that time) in 1989.


William Cherom
Treasurer and Chief Financial Officer

Mr. Cherom has nearly four decades of diverse experience in budgeting, accounting, systems, databases, organizational communications, and technical marketing.  He began his career at Hewlett Packard in Palo Alto where he worked in the Corporate Offices as well as Manufacturing Division and General Systems Division as a contributing manager in accounting and systems groups.  After working several years for a startup, Covalent Systems, Bill moved back to his hometown of San Diego where he worked a progression of financial accounting and budgeting jobs at the University of California, San Diego (UCSD).  During this time, Bill was the Financial Officer for the General Campus of UCSD and also worked as Assistant Director of the San Diego Supercomputer Center and Assistant Dean of the Rady School of Management.

Bill received his A.B. in Creative Writing from Stanford University  and an M.B.A in Accounting Information Systems from the University of California, Los Angeles.
