Adam Heller is an Israeli-American engineer, Chief Science Officer of SynAgile Corp. and Ernest Cockrell Sr. Chair Emeritus of Engineering at The University of Texas at Austin. He consults to Abbott Diabetes Care, Inc. of Alameda, California, the maker of the Freestyle line of products.
Biography
Holocaust
Adam Heller was born in 1933 to Jewish parents in the Romanian city of Cluj. In 1944, following the Second Vienna Award, the Hungarian administration confiscated his family's property, and they were forcibly relocated along with more than 18,000 other Jews to the Kolozsvár Ghetto within the walls of the Iris Brickyard. In late May of the same year, the prisoners of the ghetto at Kolozsvár were transported out of the ghetto as part of the NaziFinal Solution. Heller and his immediate family survived on Kastner's train. In 1945, he arrived in British Mandate Palestine, which became the State of Israel in 1948.
At GTE Laboratories in Bayside, New York then in Waltham, Massachusetts he developed one of the earliest liquid lasers, the first based on Nd3+ solutions in oxyhalide solvents, then with James J. Auborn the lithium thionyl chloride non-rechargeable battery with the highest energy density, 20+ year shelf life operating at the lowest and highest temperatures on earth.
At Bell Laboratories, where he headed the Electronic Materials Research Department his colleagues developed elements of high-speed electronic and optoelectronic interconnection technologies while Heller developed the first semiconductor liquid junction solar cells with efficiencies greater than 10%.
Glucose monitoring electrochemical systems for diabetes management
While a professor of engineering at The University of Texas at Austin, he and his son Ephraim Heller co-founded TheraSense in 1996, now part of Abbott Diabetes Care, Inc. He was the first Chief Technical Officer of the company. The ™ system of TheraSense, a micro-coulometer released in 2000, made the monitoring of blood glucose painless by accurately monitoring the glucose concentration in 300 nanoliters of blood. With more than a billion units produced annually, FreeStyle™ became the highest impact nanotechnology or micro-fluidic device. The FreeStyle Libre™ continuous glucose monitoring system of Abbott Diabetes Care, is the world's most widely used diabetes management system and is based on the electrical wiring of enzymes, science and technology of which were created by Heller.
Heller serves as Chief Scientific Officer of , a venture developing a continuous oral L-DOPA systems for managing advanced Parkinson's disease.
Research
His study of the physical chemistry of inorganic oxyhalide solutions resulted in the first neodymium liquid lasers. It also resulted in one of the earliest lithium batteries, the globally manufactured lithium thionyl chloride battery used in implanted medical and in defense systems where greater than a 20-year shelf life, high energy density, or operation at any temperature encountered on Earth are required. His studies of photoelectrochemical solar cells resulted in 11.5% efficient solar cells and in 12% efficient hydrogen evolving photoelectrodes. His related studies with Heinz Gerischer of photoelectrocatalysis established that the rate of photo-assisted oxidation of organic matter on photocatalytic titanium dioxide particles was controlled by the rate of reduction of adsorbed oxygen by trapped electrons. He established the field of electrical wiring of enzymes, the science and engineering of the transduction of the turnover rates of electron-transferring reactions of enzymes to electrical currents without use of diffusing oxidants or reductants. His study of the electrical wiring of glucose oxidase enables the continuous and bloodless glucose monitoring with subcutaneously implanted sensors. It is the core technology of the FreeStyle Libre™ system of Abbott Diabetes Care, having a glucose concentration transmitting skin adhered patch that is replaced every two weeks by the user. Unlike earlier monitors, it operates without periodic blood-requiring calibrations. As of October 2019, Heller and his co-inventors' patents and publications have been cited according to 122,210 times and their h-index is 169.
