Photonics erase a hindering past

Light is now enabling equal opportunity employment.

In Orange County, California, Judge David Carter has been supporting a program to remove tattoos in order to help convicted offenders to successfully re-enter community and get started on a positive path. The breakthrough will allow them to advance without telltale evidence of a hindering past.

The program, run by Stuart Nelson, Medical Director at the Beckman Laser Institute, University of California-Irvine, has already received kudos from the U.S. Probation Service in Orange County. The process employs laser light to fragment the ink particles so that they are carried away through the body’s immune system.

“This is particularly important to these clients because as they’re trying to re-enter society, acquire a job, establish a new identity and a new career, the stigma associated with having a tattoo can often inhibit that,” Nelson said.

Nelson said they’re fortunate in that most of their clients come with the popular dark blue and black inks that are easily removed by lasers. Removal can be problematic when facing chemical components called organometallic dyes, used to make colored inks.

Nelson has worked with about two dozen probationers so far, removing tattoos located on hands, lower arms and necks.

Nelson’s research focuses on laser and other biomedical optics techniques with applications such as port wine stain removal, noninvasive monitoring of blood with external probes for use by people with diabetes or for monitoring blood sugar in surgery to monitor anesthetics, cancer diagnostics and treatment, and many other life-saving, life-enhancing light-based technologies.

#FacesofPhotonics: Rising Researcher Alina Zare

SPIE's #FacesofPhotonics is sharing the story of Alina Zare, Associate Professor at the The Machine Learning and Sensing Lab at the University of Florida. Dr. Zare was recognized as a 2018 Rising Researcher for her work in Electronic Imaging & Signal Processing, at the SPIE Defense + Commercial Sensing conference.

This program recognizes early career professionals who conduct outstanding research in the defense, commercial, and scientific sensing, imaging, optics, or related fields. If you want to learn more about the program, the details are here.

Enjoy the interview with Alina!

1. Tell us about when you first became interested in optics and photonics. In my senior year of  undergraduate studies in computer science, I was taking an Image Processing elective.  I really enjoyed the course, and the professor for the class, Dr. Gerhard Ritter, encouraged me to do some undergraduate research.  
So I joined Dr. Paul Gader's research lab as a undergraduate researcher where I he…

Lighting Their Way

It's a feast for the science-curious senses: in June, two cohorts of two dozen middle-school girls came together for the free, STEM-focused, four-day-long Physics Wonder Girls Camp sessions organized by Dr. Roberto Ramos, associate professor of physics at the University of the Sciences in Philadelphia.

The girls studied the properties of light, built telescopes, designed and engineered submersible robots, and learned about scientific professions directly from the experts: nanoscientist and Chair of Bryn Mawr College's Physics Department Dr. Xuemei Cheng; INTEL software engineer Dr. Marisa Bauza-Roman; and several female food scientists from Puratos, a global company working with bakers and chocolatiers to assess the best ways to improve their products, all came and talked about their professions, answering questions and interacting with the campers. Plus, they got to be on TV!

The camp was initially inspired by Dr. Ramos' daughter Kristiana who expressed interest in the s…

#FacesofPhotonics and Women In Optics feature: IBM Researcher Anuja De Silva

Meet the SPIE Faces of Photonics star of the week, SPIE Member Anuja De Silva. Anuja grew up in Sri Lanka and now resides in Albany, New York, where she works as a materials and process researcher in the Semiconductor Technology Research division of IBM. Speaking of her work, she says, "I develop new types of materials and processes that help us to scale the size of computer chips... It's hardware development for next-generation semiconductor devices."

Anuja graduated with her Bachelor's in Chemistry from Mount Holyoke College and went on to get her Master's and PhD in Materials Chemistry from Cornell University. Upon conducting a research project for her undergraduate degree, she found her passion for optics and materials research.


"I have always been interested in math and science," Anuja shares. "The options in Sri Lanka, where I grew up, for a career as a research scientist were limited. My mother encouraged me to apply to college in the Unite…
