Laser Applications to Chemical, Security and Environmental Analysis

11 July 2022 – 15 July 2022 Hyatt Regency Vancouver, Vancouver, British Columbia, British Columbia Canada

LACSEA addresses all aspects of optical techniques and instrumentation for chemical, security, and environmental analysis. The meeting covers diagnostics of combustion and industrial process gases, atmospheric sensing and monitoring, and the analysis of gases that may contain chemical or biological agents. Sensing of liquids (e.g., aerosols) and solids (e.g., particulates or explosives) is also discussed.

Topics include exciting new developments in analytical spectroscopy, ultrafast lasers, frequency combs, and miniaturization using optical approaches spanning the VUV to THz spectral range.

Plenary Session

Juliet Gopinath

University of Colorado Boulder

From water filtration to autonomous navigation: Using photonics to enable new sensing modalities

Light can be used for exquisite sensors that can measure rotation, materials, range, chemical composition, and even the workings of the brain.   Recent advances have enabled new modalities of ranging and detection of membrane fouling.

About the Speaker

Juliet Gopinath is the Alfred T. and Betty E. Look Professor of Electrical, Computer and Energy Engineering and Physics at the University of Colorado Boulder. She received her B.S. degree in Electrical Engineering from the University of Minnesota and her M.S. and Ph.D. degrees at MIT. She was a member of the technical staff at MIT Lincoln Laboratory from 2005 to 2009. Since then, she has led a research group at the University of Colorado Boulder.

Special Events

Optical and Photonic Technologies Addressing the COVID-19 Pandemic Needs (Joint AIS and Sensors)

Monday, 11 July 10:30 – 12:30

The photonics community has made a tremendous impact in the fight against the COVID-19 pandemic. These powerful optical and photonic technologies include everything from the development of rapid diagnostic tools to address the testing crisis to wide-spread population immunity screening sensors, from imaging and analytical tools used in fundamental virology research to vaccine and drug development, and from intensive-care patient monitoring sensors to decontamination and sterilization devices.  A joint session between Optical Biological and Chemical Sensors and Applied Industrial Spectroscopy will bring leading researchers from industry, government, and academia to highlight the most recent technological developments that not only address current challenges of COVID-19, but also better prepare our communities for the future healthcare crises.  This special session encourages abstracts that focus on current and evolving technologies that may result in sensitive, rapid, low-cost diagnostic tests, analytical platforms enabling new drug and vaccine discovery, sensors that monitor patients and guide therapies, and more.
