Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering, and his research team show how they developed a new variant of photoacoustic microscopy (PAM) called needle-shaped beam photoacoustic microscopy (NB-PAM). NB-PAM has a depth of field nearly 14 times greater than what was achievable before. [Caltech story]

Scientists have developed a new ultrafast camera that can record footage of impulses as they travel through nerve cells. The camera technology, known as differentially enhanced compressed ultrafast photography (Diff-CUP), was developed in the lab of Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering. "Seeing nerve signals is fundamental to our scientific understanding but has not yet been achieved owing to the lack of speed and sensitivity provided by existing imaging methods," Wang says.

Of the many ways to treat cancer, the oldest, and maybe most tried and true, is surgery. The goal is to remove all of the cancerous tissue while preserving as much of the surrounding healthy material as possible. "It's very hard to grow bone, so if you cut out bone, you basically lose it," says Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering. A new diagnostic imaging technology developed by researchers at Caltech is offering surgeons the ability to make cuts 10 times more precisely, allowing them to preserve as much as 1,000 times more healthy tissue and to give patients easier recoveries.

Imagine driving home after a long day at work. Suddenly, a car careens out of an obscured side street and turns right in front of you. Luckily, your autonomous car saw this vehicle long before it came within your line of sight and slowed to avoid a crash. This might seem like magic, but a novel technique developed in the laboratory of Changhuei Yang, Thomas G. Myers Professor of Electrical Engineering, Bioengineering, and Medical Engineering; Investigator, Heritage Medical Research Institute, could bring it closer to a reality. "We can see all the traffic on the crossroads with this method. This might help the cars to foresee the potential danger that one is not able to see directly." explains electrical engineering graduate student Ruizhi Cao. [Caltech story]

The Defense Advanced Research Projects Agency (DARPA) has named Azita Emami to the Microsystems Exploratory Council (MEC) for a three-year term beginning this summer. Emami is Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering; Executive Officer for Electrical Engineering; and Director, Center for Sensing to Intelligence. MEC brings over 30 of the brightest scientists and engineers together to identify new areas of development in microsystems science and technology and to recommend future possible research directions. The MEC Group was established by DARPA in 2017 to support its technology offices and provide continuing and independent assessment of the state of advanced microsystem technology as it relates to the U.S. Department of Defense.

The course combines topical lectures that give the students a preview of what they will be doing in the cleanroom along with hands-on practical training. Both components are conducted as a team effort between Scherer and the KNI technical staff. The first two lectures of the term were presented by KNI’s microscopist, Dr. Annalena Wolff, who lectured on scanning electron and focused ion beam microscopy. Additional lectures were presented by KNI’s Associate Director of Technical Operations, Dr. Guy DeRose, on electron beam lithography.

Engineers at Caltech have developed an approach for quantum storage that could help pave the way for the development of large-scale optical quantum networks. "The ability to build a technology reproducibly and reliably is key to its success," says graduate student Andrei Ruskuc. "In the scientific context, this let us gain unprecedented insight into microscopic interactions between ytterbium qubits and the vanadium atoms in their environment." The new system relies on nuclear spins—the angular momentum of an atom's nucleus—oscillating collectively as a spin wave. This collective oscillation effectively chains up several atoms to store information. "Based on our previous work, single ytterbium ions were known to be excellent candidates for optical quantum networks, but we needed to link them with additional atoms. We demonstrate that in this work," says Andrei Faraon, Professor of Applied Physics and Electrical Engineering. [Read the paper] [Caltech story]

In an effort to create more opportunities for students, increase interdisciplinary research, and gain visibility for a first-of-its kind program, Caltech is creating a new graduate education track that combines medical engineering and electrical engineering. Students entering the joint track will be eligible to earn a single PhD in electrical and medical engineering, and would perform research in each field and, ideally, in a combination of the two fields. "All my students from both departments have a strong interest in this joint track," says Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering. "This will be good for them because it will broaden their horizons by exposing them to both fields. This will also allow MedE to recruit students from the EE track, and EE will be able to recruit from MedE." [Caltech story]

Yu-Chong Tai, Anna L. Rosen Professor of Electrical Engineering and Medical Engineering; Andrew and Peggy Cherng Medical Engineering Leadership Chair; Executive Officer for Medical Engineering, has been awarded the 2021 Innovation Award for Outstanding Researcher by The Southern California Biomedical Council (SoCalBio). The Award is meant to recognize and celebrate the contributions of Greater Los Angeles Region's bioscience entrepreneurs, researchers, and educators.

The Caltech Center for Sensing to Intelligence (S2I) has announced that, in collaboration with Rockley Photonics, a photonics-based health monitoring and communications solutions company, it will allocate $1.5 million in research grants over the next three years to jumpstart efforts to combine sensors with artificial intelligence. "We would like to have sensors in every device these days, generating a huge amount of data," says Azita Emami, Andrew and Peggy Cherng Professor of Electrical Engineering and Medical Engineering and the director of S2I. "But it's difficult to extract the most important information from the mountains of data they create." [Caltech story]
