Unique System for Using UVC Light to Sterilize Masks in Bulk Developed at Rensselaer

LESA researchers in collaboration with the Center for Biotechnology & Interdisciplinary (CBIS)  at Rensselaer, developed a new device for making masks reusable in the fight against COVID-19. This project began at the request of longtime research partners at Mount Sinai. As the pandemic worsened in New York City, and the shortage of PPE deepened, they asked if Rensselaer could develop a way to make critical resources last longer without losing their effectiveness. The speed with which the Rensselaer team devised and built this solution expedites the possibility that it will be helpful in the fight against the pandemic. A design and construction process that often takes months, or even years, was completed in a matter of weeks.

U.S. Department of Energy Awards $2.8M to LESA

The Department of Energy announced February 10, 2020  – $74 million awarded for 63 selected projects to, ‘research, develop, and test energy-efficient and flexible building technologies, systems, and construction practices to improve the energy performance of the Nation’s buildings and electric grid.


11th Annual Industry-Academia Days Speakers Announced

IADays2020 has been postponed due to issues related to COVID-19 and Resnsselaer’s protocol for social distancing at this time. This year’s theme:“How do we get to SMART Cities?” will include insights on how we take the fundamentals of the built environment, integrated into the elements of a SMART Cities infrastructure, and use them to create the SMART Connected Communities of the Future.  […]

UNM Study Gauges Effectiveness of Light Therapy to Reshape Circadian Rhythms

University of New Mexico researchers and their colleagues from the LESA Center have demonstrated a new technology for gauging the effectiveness of light therapy to synchronize human circadian rhythms as a potential treatment for insomnia, mood disorders and other health problems.  In a report published online in the IEEE Journal of Translational Engineering in Health and Medicine (and set to lead the journal’s December issue), the team reported on a pilot study using the Smart Lighting Clinical Testbed at UNM Hospital. The lighting, sensing and control systems used were based on a system first installed in the Smart Conference Room Testbed at the LESA Center.

LESA & GLASE Experts Offer Insights into Controlled Environment Agriculture in LEDs Magazine Blog Series

The LESA Center at Rensselaer Polytechnic Institute and the Greenhouse Lighting & Systems Engineering (GLASE) consortium experts from Cornell University participated in a four-part guest blog series with LEDs Magazine between July and October. Throughout the series, they discussed research methods, applications, industry trends and future farming insights for controlled environment agriculture. The blog series was extremely popular generating significant interest around LESA and GLASE research initiatives. Two of the four blogs were ranked among LEDs ‘Top 5 Blogs of 2019’ – including the number 1 spot. […]

LESA Researchers Published in PLOS ONE for Work on Optimizing Sleep and Alertness

Agung Julius and John T. Wen’s research findings were recently published in PLOS ONE for their work on time optimal entrainment control for circadian rhythm regulation. They have developed ‘new ways to optimize sleep for alertness through light exposure‘ and were featured on Rensselaer News. Their work is part of ongoing research at LESA, resulting in several subsequent publications around circadian function, circadian phase shift, and the effects of healthy lighting funded by the Army Research Office, the Department of Homeland Security, and the Department of Defense.  […]
