Executives
Stuart A. Cain, Ph.D., President. Stuart came to Alden in 1996, after receiving two bachelor’s degrees (one in Physics and one in Aerospace Engineering) and an M.S. and a Ph.D. in Mechanical Engineering. He built Alden’s numerical modeling capability from scratch. He was an Alden Vice President for six years, during which time he had formal responsibilities of overseeing hydraulic and numerical modeling activities as well as flow meter calibration. Additionally, he has served as the Alden treasurer and has played key roles in strategic decisions associated with gas flow engineering and environmental and engineering services. Stu has extensive experience in power plant engineering, environmental engineering, manufacturing, and modeling. He has been president since May of 2009.
David K. Anderson, Senior Vice President. David is responsible for gas flow engineering and environmental engineering services at Alden. In addition to participation in selected projects, he provides overall technical and fiscal management. His particular expertise is in the areas of thermal and fluid dynamics, especially in their application to research problems and the presentation of laboratory results in the form of realistic and practical engineering recommendations. David has over 22 years of research and product development experience associated with fossil power generation and environmental control systems. He has numerous patents relating to improved steam generator components, injection and firing systems, flow measurement systems, dampers and mist eliminators.
Daniel Gessler, Ph.D., P.E., Vice President, Director of Colorado Operations. Dan is responsible for operations in the Alden Fort Collins, Colorado office, including business development efforts and hydraulic modeling using numerical methods. Tools employed are computational fluid dynamics (CFD) software as well as one- and two-dimensional hydraulic models, including sediment transport. In addition, he provides technical expertise on physical models, particularly when sediment is involved.
Directors
Greg Allen, P.E., Director of Environmental and Engineering Services. Greg is responsible for leading a dedicated and accomplished staff of scientists and engineers who perform biological and engineering evaluations for water resources projects. He has extensive experience performing feasibility studies and detailed designs for fish protection and passage facilities and debris management solutions at dams, hydroelectric projects and cooling water intakes. His experience includes 316(b) NPDES permit compliance, engineering feasibility studies, hydrology and hydraulic analysis, detailed designs, fabrication and construction drawings, specifications, operating and maintenance manuals, construction inspection as well as evaluating and testing hydrokinetic turbines.
Andrew E. Johansson, Director of Hydraulic Modeling. Andy is responsible for the technical and fiscal management of the hydraulic modeling and consulting team. He has 20 years of experience providing day-to-day supervision of engineering studies and model studies during design, construction, and testing modes. These studies include hydraulic and 3D air models. Areas of particular expertise include the evaluation of intakes, outlets, stilling basins, pump sumps, navigation locks, control gates, spillways, etc. Current hydraulic modeling efforts include pump sump studies where the formation of vortices and approach flows and configurations could affect pump performance, grit deposition studies for wastewater treatment plants and hydraulic studies of drainage canals.
Mark L. Kosakowski, Director of Field Services. Mark joined Alden in 2008 and is responsible for all field measurement services performed by Alden. He has managed numerous field investigations conducted in support of NPDES permitting and design of power plant, industrial and wastewater outfalls, environmental impact assessment of port and harbor development, marine crossings (pipeline, cables and bridges) and marine resource development. These studies entailed a full spectrum of marine survey services including the deployment and servicing of current meter, wave and tide gauge arrays, dye tracer studies, drifting drogue tracking, water quality monitoring, satellite telemetry, limnological data collection and analysis, meteorological monitoring, and hydrographic surveys.
Martin J. Kozlak, Director of Gas Flow Engineering. Marty is responsible for gas flow engineering at Alden, using industry knowledge and expertise as well as physical and computational fluid dynamic (CFD) models. In addition to participation in selected projects, he provides overall technical and fiscal management, directing the team of engineers, technicians and craftspeople responsible for developing efficient and cost-effective solutions. His particular expertise is in the area of thermal and fluid dynamics, especially in their application to research problems and the presentation of laboratory results in the form of realistic and practical engineering recommendations. He also has considerable experience with large ash particle mitigation in post-combustion environmental control equipment and in both single phase and two-component flow regimes. Marty has over 25 years of experience directing research and product development related to fossil power generation and environmental control systems. He has numerous patents relating to improved steam generator components, injection and firing systems, coal pulverization and flow measurement systems.
David G. Schowalter, Ph.D., Director of Marketing and Business Development. Dave leads the strategic marketing and business development activities at Alden. In addition to guiding business operations, the position involves providing technical direction and advice on key projects involving physical modeling and computational fluid dynamics. He has twenty years of fluid dynamics experience, including eight years of academic R & D and twelve years in industry, ten of which involved marketing and business development responsibilities.
Philip Stacy, Director of Flow Meter Calibration Services. Phil is responsible for all flow meter testing performed in Alden's renowned flow measurement facilities. He provides technical and administrative supervision of Alden's Flow Measurement Department to insure the highest standard for calibrating fluid meters, ranging in size from fractional inches to 48", to a NIST traceable uncertainty of less than 0.2% in accordance with ASME requirements. Phil has 22 years of hydraulic engineering experience, including physical modeling and he is also responsible for field performance measurements of hydroelectric turbines and pumps, applying code accepted methods using current meters and dye dilution for flow measurement.
Lori Seppala, Director of Finance. Lori has been at Alden since 1996. She began as the accounting and purchasing clerk, and her extensive on-the-job training has given her the comprehensive knowledge of accounting and financial practice that enables her to advise the board on related decisions. Since becoming director in 2010, she has been responsible for all financial and fiscal management aspects of Alden’s operations. She provides leadership and coordination in the accounting and budgeting efforts of the company.
