Cutting Down on Cancer Surgeries


Engineers at the Optical Imaging Laboratory led by Professor Lihong Wang have developed an imaging technology that could help surgeons removing breast cancer lumps confirm that they have cut out the entire tumor—reducing the need for additional surgeries. “What if we could get rid of the waiting? With 3D photoacoustic microscopy, we could analyze the tumor right in the operating room, and know immediately whether more tissue needs to be removed,” Professor Wang explains. [Caltech story]

Laser-Induced Sound Waves Provide Live Panoramic Views of Tissue Functions


Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, and colleagues are now able to take a live look at the inner workings of a small animal with enough resolution to see active organs, flowing blood, circulating melanoma cells, and firing neural networks. "Photoacoustic tomography combines light and sound synergistically for high-resolution imaging of molecular contrast," says Professor Wang. [Caltech story] [Read the paper]

Black Silicon Prevents Eye Implant from Gumming Up


Hyuck Choo, Assistant Professor of Electrical Engineering; Investigator, Heritage Medical Research Institute, and colleagues have developed an eye implant for glaucoma patients that could one day lead to more timely and effective treatment. Professor Choo has developed a passive system that eschews electronics and so needs no batteries and has no antennae. At just 600–800 micrometers in diameter, the sensor is the width of a few strands of hair. [Caltech story]

Panda Express Co-founders Give $30 Million to Caltech for Medical Engineering


The Andrew and Peggy Cherng Department of Medical Engineering (MedE) is the first Caltech department to be named and endowed. “We are here to build the American dream, but not just for us. We want to give to the right cause, and medical engineering will help others. I see Caltech helping to create a bright future ahead,” says Caltech trustee Peggy Cherng. Founded in 2013, the MedE department brings together scientists and engineers from across campus to improve medical diagnostic and treatment strategies. [Gift announcement]

Seeing Deeper: An Interview with Lihong Wang


Using a combination of light and sound, Professor Lihong Wang is noninvasively peering deeper inside biological tissues than previously possible. His team uses three-dimensional photoacoustic microscopy and functional photoacoustic computed tomography to generate detailed color images of tumors and other structures inside the body.

Professor Tai Elected to National Academy of Inventors


Yu-Chong Tai, Anna L. Rosen Professor of Electrical Engineering and Mechanical Engineering; Executive Officer for Medical Engineering, has been named fellow of the National Academy of Inventors (NAI). He works on miniature biomedical devices including drug pumps, retinal implants, spinal cord implants, and more. He recently developed a device to count white blood cells that requires just a pinprick's worth of blood and processes samples in minutes. Election as an NAI fellow is an honor bestowed upon academic innovators and inventors who have "demonstrated a prolific spirit of innovation in creating or facilitating outstanding inventions and innovations that have made a tangible impact on quality of life, economic development, and the welfare of society."
