A Quantitative Snapshot of the Human Impact on the Planet


Caltech researchers have developed a database containing global data on how humans have impacted the planet. The Human Impacts Database is designed to be accessible to scientists, policymakers, and everyday citizens. "In my view, the root to understanding is numeracy: once you have the numbers, it becomes clear what the problems are, which things are significant, and which things are less so," says Rob Phillips, Fred and Nancy Morris Professor of Biophysics, Biology, and Physics.

EAS Remembers Roy W. Gould


Roy W. Gould, Simon Ramo Professor of Engineering, Emeritus, passed away on February 19, 2022. He was 94 years old. Gould earned his bachelor's degree from Caltech in 1949, a master's from Stanford University in 1950, and a doctorate from Caltech in 1956. After leaving Stanford, he worked as an engineer on missile guidance and control at JPL, which Caltech manages for NASA, and then at Hughes Aircraft. He joined Caltech's faculty in 1955. Gould started as an Assistant Professor of Electrical Engineering, became Associate Professor of Electrical Engineering in 1958, Associate Professor of Electrical Engineering and Physics in 1960, and Professor in 1962. He was named Professor of Applied Physics in 1974 and became Ramo Professor of Engineering in 1980. He served as Executive Officer of Applied Physics from 1973–79 and Chair of the Division of Engineering and Applied Science from 1979–85. Gould's research focused on plasma physics and thermonuclear fusion. During his long career, Gould earned numerous awards and recognitions. [Caltech story]

Caltech Startup Aims to Make Solar Panels More Efficient


Translational technology developed in Professor Harry A. Atwater’s laboratory seeks to improve the efficiency of solar panels by tweaking the architecture of the metal-grid layout of individual cells. The new startup company—ETC Solar, LLC—which is marketing the technology, took first place at the DOE's 2018 Cleantech University Prize national collegiate business plan competition in Houston. "To have been selected as a winner is a huge point of validation for the concept, both the innovation and also the impact," says Professor Atwater, who is also a co-founder of ETC Solar along with Thomas Russell, and Rebecca Saive. "It has helped us to make contacts with potential industrial partners and private equity investors," [Caltech story]

Engineered Metasurfaces Replace Adhesive Tape in Specialized Microscope


The latest advance in a new type of optics aimed at improving microscopy started with a game of tennis three years ago between Mooseok Jang a graduate of Professor Changhuei Yang's lab and Yu Horie working with Professor Andrei Faraon. "The hope is that our work will prompt further interest in this area of optics and make this type of microscopy and its advantages feasible for practical, everyday use—not just as a proof of concept," says Josh Brake, a graduate student in Yang's lab who continues to work on the project with Faraon and Yang.

A Bright Future in Photovoltaics


Alumna Carissa Eisler discusses her passion for science and her research in Professor Harry Atwater’s group on photovoltaics—the conversion of solar energy into electrical energy using semiconducting materials. She was part of a group tasked with developing an ultrahigh-efficiency solar-cell module that involves designing solar collectors, optical components, and electronics.
