Professor Scherer Elected to National Academy of Inventors


Axel Scherer, Bernard Neches Professor of Electrical Engineering, Applied Physics, and Physics, has been named fellow of the National Academy of Inventors (NAI). He has most recently developed ways to integrate optics, electronics, and fluidics into sensor systems. Much of his work is currently focused on systems for medical diagnosis and health monitoring through molecular pathology and wireless implants.  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."

Sensors to Simplify Diabetes Management


As part of their Summer Undergraduate Research Fellowship (SURF) projects, several engineering students have contributed to the development of tiny biosensors that could one day eliminate the need for manual blood sugar tests. The students were advised by Caltech medical engineering faculty Axel Scherer, and Hyuck Choo. [Caltech Release] [ENGenious MedE Feature]

Senior Spotlight


Electrical Engineering Senior Raymond Jimenez was first introduced to Caltech as a high school student when he worked in the laboratory of Paul Bellan. As a Caltech undergraduate his favorite class was APh/EE 9, Solid-State Electronics for Integrated Circuits—a course then taught by Oskar Painter. He also worked on a Summer Undergraduate Research Fellowship (SURF) project with Axel Scherer, who describes Jimenez as "one of the most capable undergraduates whom I have had the pleasure of working with over my past 20 years at Caltech," adding that he has "extraordinary" abilities. "Raymond brought tremendous enthusiasm, talent, and insight to our neural probe project," Scherer says. "It was fun working with him on our research projects, and I think of him more as a scientific collaborator than as a student." Raymond and his peers will be honored at Caltech's 119th Commencement on June 14 at 10 a.m. [Caltech Spotlight]

Disease Diagnosis at the Touch of a Button


Axel Scherer, Bernard Neches Professor of Electrical Engineering, Applied Physics and Physics, and colleagues have built a new version of a polymerase chain reaction (PCR) device, which generates many copies of a pathogenic nucleic acid, allowing the infection to be detected. The device is the result of nearly 10 years of research at Caltech. In 2004, Scherer, a leader in the field of microfluidics, and George Maltezos were investigating how to manipulate biological fluids on a chip. While this was an interesting engineering problem, Maltezos began to wonder how he could apply the microfluidic techniques that he was perfecting to real-world problems. Then the H5N1 bird flu pandemic erupted in Asia, and the team had their real-world problem. [Caltech Release]

Engineers Solve Longstanding Problem in Photonic Chip Technology


Liang Feng, a Postdoctoral Scholar in Electrical Engineering who works with Professor Axel Scherer, has designed a new type of optical waveguide - a 0.8-micron-wide silicon device. The waveguide allows light to go in one direction but changes the mode of the light when it travels in the opposite direction. This new technique to isolate light signals on a silicon chip, solves a longstanding problem in engineering photonic chips. [Caltech Press Release]
