Employee Profiles
John Lorentsen | Mark Smith | Jay Miller | Michael Titone | Mike Marunde | Liz Kaperson
JOHN LORENTSEN is a founding partner of Mid-America Dynamics, incorporated in 1990. He has over 20 years experience in the operation of power generation equipment, vibration analysis, balancing, modal analysis, and large-scale data acquisition.
Mr. Lorentsen was employed by Commonwealth Edison for over nine years where he was responsible for vibration analysis and balancing at ten fossil-fueled and six nuclear plants. He developed several computer based data acquisition systems including a stored influence coefficient fan balancing system for use by plant personnel. Since that time, Mr. Lorentsen has been involved in developing predictive maintenance programs at large industrial sites, including several power plants, paper plants, and steel mills. He has developed methods for monitoring and analyzing variable speed machinery and has conducted numerous training classes, teaching these methods.
Mr. Lorentsen has specified and managed the installation of several on-line vibration monitoring systems including Turbine Supervisory Instrumentation (TSI) on large turbine generator sets, and networked systems on many large papermaking machines. He has also used his knowledge of signal analysis techniques in the testing of non-rotating equipment such as nuclear power plant check valves and in the structural redesign of various power plant components.
Mr. Lorentsen received a B.A. degree from Taylor University and a B.S. degree in mechanical engineering from the University of Illinois at Champaign-Urbana.

MARK SMITH is a founding partner of Mid-America Dynamics, incorporated in 1990. He has extensive experience in vibration analysis, balancing, predictive maintenance, strain gage testing, radio telemetry, instrumentation calibration, and large-scale data acquisition. He also has supervised the installation of many TSI and other automated data collection systems.
Mr. Smith was employed by Commonwealth Edison from 1983 to 1990 an in-house consultant for the company's sixteen generating stations. In that capacity, he was responsible for coordinating the startup and day-to-day support of the predictive maintenance programs at each of the generating stations. He also performed vibration analysis and balancing of rotating machinery on a wide variety of equipment.
Mr. Smith has also been involved in a diverse range of mechanical testing and analysis and instrumentation projects involving piping vibration, strain measurement, rotor torsional response, moveable bridge balancing, control valve response, and continuous on-line machinery monitoring. Mr. Smith has provided consulting, training, calibration, and project management services to the power, steel, paper, petrochemical, manufacturing, and food industries.
Mr. Smith received BS and MS degrees in mechanical engineering from the University of Illinois at Chicago and is a licensed professional engineer. He has had several papers published on vibration analysis, predictive maintenance, and remote monitoring applications.

JAY MILLER is a Consulting Engineer at Mid-America Dynamics. He has over twenty years of experience in vibration analysis, balancing, predictive maintenance vibration monitoring, laser alignment, training, instrumentation systems, and modal analysis.
Mr. Miller joined Mid-America Dynamics after working two years in customer support for a company that represented a number of predictive maintenance product lines. In that capacity, he coordinated or assisted in the startup of predictive maintenance programs in a variety of industries.
Prior to that, he worked as an in-house consultant for nine years at Commonwealth Edison. There, his primary responsibilities were to advance the company's predictive maintenance vibration monitoring program, provide vibration analysis of many types of power plant machines, and to perform turbine-generator vibration analysis and balancing.
Mr. Miller received a BS in mechanical engineering from the Illinois Institute of Technology. He is a member of the Vibration Institute and has given several presentations and training seminars, and published papers on vibration analysis, predictive maintenance, and balancing.

MICHAEL TITONE is a Consulting Engineer at Mid-America Dynamics. He has over fourteen years of experience in vibration analysis, balancing, predictive maintenance vibration monitoring, mechanical system design and analysis, and instrumentation and controls system design.
Mr. Titone joined Mid-America Dynamics after working for Entergy in several positions. Most recently, his primary responsibility was to oversee the vibration analysis and monitoring program for five oil and gas burning power plants. In this role, he monitored and analyzed transient vibration data, balanced equipment, and provided general troubleshooting advice in addition to managing the routine activities of the program.
Prior to his work in the fossil organization, Mr. Titone worked in the mechanical systems design group at Grand Gulf Nuclear Station, in the central design engineering group at Entergy’s nuclear headquarters organization in Jackson, MS, and in the instrumentation and controls design group at Grand Gulf. In these roles, he performed steady state pressure and flow analyses of piping systems, analyzed cooling tower performance, led and participated in corporate projects, and oversaw the mechanical aspects of instrumentation and controls projects.
Mr. Titone earned a BS in mechanical engineering from Louisiana Tech University and an MBA from Mississippi College. He earned eighteen hours of graduate engineering credit from Mississippi State University and Georgia Tech. He is a member of the Vibration Institute and the American Society of Mechanical Engineers. He is a licensed professional engineer, a certified Category III Vibration Analyst through the Vibration Institute, and a certified Level I Machine Lube Analyst through ICML.
