Expert has over 20 years of experience in the energy storage field.

1. From 1997 to 2002 he worked with a large format Li-ion cells (up to 100Ah) developer on a US Air Force program where he characterized the cells, developed state-of-charge (SOC) algorithms, battery management systems (BMSs) and chargers.
2. From 2002 to 2004 he worked on an Army research Program involving development of a Li-ion battery for a small robotic vehicle. Through extensive testing and analysis, he determined the propulsion power requirements of the vehicle for various terrains and translated them to the battery requirements. He next developed a 24V, 7Ah Li-ion battery where he selected the cell supplier, led the battery design and defined the functional and safety test requirements. He integrated the battery with the vehicle and supported field testing of the battery at various Army facilities.
3. During the 2005 -2008 timeframe Expert was involved in the development 28V, 10Ah Flight Control Battery for Boeing 787 aircraft. In this role he drove the overall battery architecture and battery management electronics design. He supported the project through build, test and certification.
4. During 2008-2009 he served as the battery expert on the Chevrolet Volt battery safety analysis project. He performed detailed analysis of the cell pack, BMS and cooling system of the battery. The Fault Tree Analysis and Failure Mode Effects Analysis of the battery were conducted to access safety. A comprehensive battery evaluation report recommending solutions to the detected issues was submitted to the customer.
5. During the 2009-2012 time frame he worked as the Principal Investigator on the Hybrid Emergency Power Systems R&D Project where he characterized Li-ion batteries and supercapacitors. This project used NMC Li-ion chemistry for which he developed novel SOC determination algorithm. He also developed a battery characterization system consisting xPC target hardware for simulation testing of the algorithms. He designed and tested passive and active battery-supercapacitor hybrid system and defined control strategies for the active hybrid system employing Matlab/Simulink software.
6. From 2012 to date (6 years) Expert has been serving as Lead Battery Technologist within Honeywell Aerospace. In this role he has been supporting business development in the aviation, space, military, ground vehicles and grid areas. He has also been leading the R&D projects where he developed a 28V, 40Ah aircraft battery and SOC/SOH algorithms for the lithium titanate oxide (LTO) and lithium cobalt oxide chemistries resulting several patents. He performed successful testing of the LTO battery in accordance with the stringent test requirement of the RTCA DO-311A draft standard including the full battery thermal runaway testing. He has also directed cell testing in an adiabatic chamber to obtain thermal and pressure data need for battery design. He was a key member of the RTCA SC-225 and 235 of the RTCA Special Committees responsible for developing chargeable and non-rechargeable aircraft battery standards.

Expert may consult nationally and internationally, and is also local to the following cities: New York, New York - Yonkers, New York - Newark, New Jersey - Jersey City, New Jersey - Paterson, New Jersey - Elizabeth, New Jersey - Bridgeport, Connecticut - New Haven, Connecticut - Stamford, Connecticut - Philadelphia, Pennsylvania
