Cornell Engineering Alumni Inventors

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
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, and




Allyson D. Yarbrough (M.S. 1985, Ph.D. 1988, ECE)

Micromachined Electronic and Electromechanical

Jerry M. Woodall (Ph.D. 1982, EE)

Pioneer in Research and Development

of Compound Semiconductor Materials

and 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.

“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.”
