Circadian, Sleep and Neurobehavioral Performance Engineering @ LESA

Human circadian rhythm regulation is linked to many physiological processes, including sleep. Circadian disruption is known to have negative impacts on health and may lead to lower human performance and higher risk of failure during critical tasks.  By understanding the relationships between human circadian processes, sleep processes, and cognitive performance, improved management of lighting and task scheduling can be developed to favorably impact overall human health and performance.

LESA, Cornell and NYSERDA announces the launch of a multidisciplinary consortium to reduce electricity use in greenhouses up to 70%. Greenhouse Lighting and Systems Engineering (GLASE), a seven-year $5 million project funded by NYSERDA, is being launched to transform the way greenhouses operate reducing both energy cost and carbon footprint.  Dr. Tessa Pocock, Senior Research Scientist at LESA will lead the work at Rensselear.

Recent advances in solid state lighting technology are enabling the development of ‘designer’ crops, according to Rensselaer Polytechnic Institute plant physiology expert Dr. Tessa Pocock, who serves as a senior research scientist at the Center for Lighting Enabled Systems & Applications (LESA). The impact of lighting on plants is the core focus for Pocock, who conducts research in both academic and industry settings around the mechanism of photosynthesis on plant development and regulation by light for traditional greenhouse crops and the emerging field of medicinal plants. Recently, Pocock and her team received a $25,000 grant from Dr. William Beers, Black Belt/Senior Systems Engineer at Current, powered by GE, to support continued work on sensing and signaling in plants.

LESA Alum Dr. Jessica Morrison has formed a startup, Helux Lighting, Inc to bring dynamic optical control to the market through microtechnology developed at Boston University.  These micro-mirrors are an example of micro-electromechanical systems (MEMS) that can steer a beam of reflected light by applying a voltage.  The tiny mirrors steer light faster that the human eye can detect and facilitate rapid control over light position, brightness, and illumination area.  The competitive advantage of Helux technology is a tenfold reduction in size and lower cost when compared to existing mechanical systems for light control.
