Overview:

Dr. Panzarella is the technical and management lead on a number of software development and applied research endeavors at E2G.  He is proficient in many fields of applied science and engineering and has many decades of experience working as a researcher and scientific programmer in academia, industry, and government labs.  His work has been published in a number of peer-reviewed journals such as The Journal of Fluid MechanicsThe Journal of Spacecraft and RocketsThe International Journal of Thermophysics and Heat Transfer, and Cryogenics.  He has a practical mindset that is rooted in rigorous mathematical training but supplemented by advanced engineering knowledge and modern software development skills. 

Dr. Panzarella has been with E2G since 2005 and has held the position of Chief Technology Officer (CTO) since 2010.  As the CTO, he has been primarily responsible for leading applied research projects that are ultimately translated into new consulting methods and software products.  He managed the Technology & Software Products Team for many years and led it towards being a successful and profitable team.  He then founded and is currently directing the activities of the Applied Research & Development Team (recently renamed to the Innovative Software & Research Team) to expand the business opportunities of the company.  He led the development of the next generation of engineering methods and software products delivered through a modern web-based delivery platform (eec).  He is currently focusing on founding and kickstarting new subsidiaries of E2G that are incubating and commercializing the most innovative new technology that stems from E2G’s own internal research efforts as well as through partnerships with other companies
