Lasers Aim to Replace Scalpels in Cutting-Edge Biopsy Technique


Professor Lihong Wang and Postdoctoral Scholar Dr. Junhui Shi have developed a new imaging technique that uses pulses from two kinds of lasers to take pictures of microscopic biological structures. This new approach, called ultraviolet-localized mid-infrared photoacoustic microscopy, or ULM-PAM, develops images of the microscopic structures found in a piece of tissue by bombarding the sample with both infrared and ultraviolet laser light. "Because ultraviolet light and infrared have different properties, we had to find special mirrors and glass that could focus both," Dr. Shi says. "And because no camera exists that can see both, we had to develop ways to see if they were correctly focused." [Caltech story]

Bob McEliece Passes Away


Robert J. McEliece (BS '64, PhD '67), Caltech alumnus and Allen E. Puckett Professor and Professor of Electrical Engineering, Emeritus, passed away on May 8, 2019 at the age of 76. "Bob McEliece was renowned for his contributions to a wide range of problems in information transmission and storage," said EAS Chair Ravichandran. "His contributions are drivers for numerous applications in modern communications. He was an outstanding researcher and a beloved and inspiring teacher, mentor, and colleague." [Caltech story]

Professor Marandi Wins Young Scientist Award


Alireza Marandi, Assistant Professor of Electrical Engineering and Applied Physics, has received a 2019 Young Scientist Award of the International Union of Pure and Applied Physics (IUPAP). He was recognized “for contributions to nonlinear photonics, particularly his pioneering work on computing with networks of Optical parametric oscillators (OPOs) and demonstration of optical Ising machines, as well as half-harmonic generation of mid-infrared frequency combs.” [List of award winners]
