Prior to starting Epsilon Imaging, Mr. Sieczka was a co-founder and the Vice President of Operations for EOTech Inc, where he built the operations from a start-up product concept, into a world-class, fully integrated manufacturing facility with optical, electrical, and mechanical design capabilities servicing markets around the globe. Prior to his departure, Mr. Sieczka helped orchestrate the successful sale of EOTech to L-3 Communications (a $10B publicly traded defense contractor). Mr. Sieczka has eight patents covering an array of electro-optic technologies. He holds a BSEE degree from Kettering Institute and an MBA from the Ross School of Business at the University of Michigan.
Jamie Hamilton, PhD, Vice President and Chief Technology Officer - Dr. Hamilton is responsible for providing technical leadership and identifying opportunities for Epsilon Imaging’s image processing technologies. Throughout his career, he has developed state of the art imaging systems for the medical, defense and scientific communities. His dissertation explored high resolution ultrasound imaging using laser and optical detection methods. During his time at GE Medical Systems ultrasound group, he worked on next generation processing architectures and image quality enhancements. Later, he joined General Dynamics Advanced Information Systems where he developed wavefront sensing techniques for electro-optic systems and image restoration algorithms for radar and optical imagery. Dr. Hamilton holds a B.S. degree from the University of Rochester, and M.S. and Ph.D. degrees in physics from the University of Michigan. He has authored numerous journal publications and holds four patents on ultrasound-based technologies.
Heather Grisham, Chief Financial Officer - Ms. Grisham manages the business operations for Epsilon Imaging, including the finance/treasury, human resources, contractual, and legal functions. She brings over 18 years of experience in small business and early-stage companies, specializing in finance, intellectual property management and federal contracting. As CFO for Epsilon Imaging’s former parent company, Pixel Velocity, Ms. Grisham was involved in raising capital for the business, including several debt and equity-based financing transactions, and securing federal and state funding sources for technology development. Prior to Epsilon Imaging and Pixel Velocity, Ms. Grisham was the Controller and a Financial Analyst for the Center for Automotive Research in Ann Arbor, Michigan. Ms. Grisham holds a BS from the University of Michigan and an MBA from the Ross School of Business at the University of Michigan.
Paul Kortesoja, Director of Operations - Mr. Kortesoja is responsible for the overall operations, including medical device engineering development activities, regulatory compliance, and clinical research. He brings over 25 years of high-technology systems engineering and project management experience to Epsilon Imaging. Prior to joining Epsilon Imaging, Mr. Kortesoja was a lead engineer with General Dynamics Advanced Information Systems where he managed the development, delivery and field support of systems for processing satellite imagery, transportation research, industrial automation and medical imaging analysis. Mr. Kortesoja began his career at The Johns Hopkins Applied Physics Laboratory developing computer hardware for system simulators. Mr. Kortesoja has co-authored one patent and holds a BS (CompE) and an MBA, both from the University of Michigan.
Sean Lucas, Clinical Research Manager - Mr. Lucas is responsible for the clinical research strategy for Epsilon Imaging. Most recently he was with GE Healthcare for over 10 years, where he held positions in both product development for their engineering division and clinical research management in their marketing division. His range of expertise resides in both ultrasound imaging as well as computed tomography where he was managing the clinical research for their cardiovascular CT systems. As a clinical research manager at GEHC, he was responsible for managing multiple feasibility studies as well as a large multicenter study comparing the utility of CCTA for detection coronary artery disease with nuclear medicine. He received his BS in EE as well as Masters degrees in both Electrical Engineering and Biomedical Engineering, the latter at the University of Michigan where he was involved in breakthrough research in ultrasound hyperthermia. In addition, he holds four ultrasound patents in colorflow imaging.
