David M. Lederman (Ph.D. 1966, EP)
“The AbioCor device itself is totally implantable. An external tool – a coil – transfers battery power through the skin and into the device. A full charge can last 30 to 40 minutes. The external portion can also be plugged into an electric outlet if the patient remains in one area.” -www.masshightech.com

Robert S. Langer (B.S. 1970, ChemE)
Biomedical Applications of Polymers
After Cornell, Robert Langer graduated from MIT with a Ph.D. in 1974. He is now the Kenneth J. Germeshausen Professor of Chemical and Biomedical Engineering at the Massachusetts Institute of Technology.
One of history’s most prolific inventors in medicine, Dr. Langer’s 500 issued and pending patents have been licensed or sublicensed to over 100 pharmaceutical, chemical, biotechnology and medical device companies; a number of these companies were launched on the basis of these patent licenses. Langer pioneered the field of controlled drug delivery using biodegradable polymers. He was the first to engineer synthetic materials that allow for the precisely timed release of chemicals through surgical implants inserted directly within the diseased tissue. Langer’s controlled delivery techniques have been used to treat brain cancer right at the source instead of through damaging chemotherapy. Through Langer’s innovations, the controlled drug delivery industry has become a multibillion-dollar-a-year business that prolongs and saves thousands of lives.
Dr. Langer’s most recent work is with tissue engineering and human tissue regeneration. His goal is to engineer a synthetic framework on which to grow human cells.
He has patents in magnetically controlled drug-release implants, transdermal ultrasound drug delivery, 3D polymer scaffolds for growing human tissue, microchip drug delivery, and biocompatible shape-memory polymers that return to predetermined forms once inside the body.
Dr. Langer is the only active member of all three US National Academies–Engineering, Sciences, andMedicine.

Jerry M. Woodall (Ph.D. 1982, EE)
Pioneer in Research and Development of Compound Semiconductor Materialsand Devices
Received National Medal of Technology award at White House, 2002.
Currently C. Baldwin Sawyer Professor of Electrical Engineering, Yale University.
Fully half of the world’s annual sales of compound semiconductor components are based on Woodall’s pioneering research in that area, and he is the inventor of many electronic and optoelectronic devices commonly seen in modern life, including the red light-emitting diodes (LEDs) used in indicators and stop lights; the infrared LEDs used in CD players, TV remote controls and computer networks; the high-speed transistors used in cell phones and satellites; and high-efficiency solar cells used to power satellites.
He built the first high-purity single crystals of gallium arsenide, enabling the first definitive measurements of carrier velocity versus electric field relationships, as well as gallium arsenide crystals used for the first non-supercooled injection laser. He and Hans Rupprecht pioneered the liquid-phase epitaxial growth of high efficiency infrared LEDs, and gallium aluminum arsenide (GaAlAs), which led to his most important research contribution so far: the first working gallium aluminum arsenide/gallium arsenide heterojunction, the interface between two different semiconductor materials. This remains the world’s most important compound semiconductor heterojunction.
Dr. Woodall co-founded LightSpin Technologies, Inc., a high technology startup company, and serves as its Chief Science Officer. He hold 67 patents.
