About the Course

Working in partnership, GLASE, OptimIA, and LAMP are excited to announce the first annual Plant Lighting Short Course! This 6-week modular short course is designed to provide participants the opportunity to learn about all aspects related to the selection, implementation, and benefits of plant lighting systems. In each sequential module, attendees will use interactive tools to define their specific lighting requirements, hear from industry experts about available horticultural lighting systems, and learn how to compare different lighting strategies. By the end of the course, participants will be equipped to make informed decisions about the best options to meet their lighting needs.

Fluence Bioengineering

Dr. David Hawley leads the scientific research initiative at Fluence by OSRAM as the company’s Principal Scientist. His experience in controlled environment systems, horticultural lighting and cannabis metabolome naturally underpins Fluence’s mission to drive industry-leading lighting research to explore the interaction between light and life. During his time at the University of Guelph—where he received his bachelor’s, master’s and doctoral degrees—Dr. Hawley’s passions and research specialties merged in the lab, where he investigated the relationships between spectral quality and the three pillars of plant development: yield, morphology and plant quality. His doctoral studies also included the exploration of cannabis photochemistry and metabolism, after which he earned one of the first doctorates in North America focused on cannabis production.

Drew Koschmann

Head Grower

Walters Gardens

I have been Head Grower for the Greenhouse at Walters Gardens for six years. I graduated from Purdue University with a degree in Horticulture Production & Marketing. Walters Gardens currently has over 500,000 sq ft of greenhouse space and field space totaling close to 1,500 acres. Walters has a strong commitment in introducing new varieties of perennials and providing the highest quality to our customers. My responsibilities include: educate, coaching, and managing growers on watering, nutrient management, trimming, and PGR management of our plug material. We grow and sell plugs of 128s, 72s, 20s, and 30s. I also work closely with growers on developing location of product in our greenhouses to hit our target finish weeks. A good portion of our product is shipped during late winter/early spring months which requires us to use lighting and environmental control systems to help finish the plants for sales.

Executive Director


Dr. Erico Mattos is the executive director of the Greenhouse Lighting and Systems Engineering consortium and co-founder and CEO of Candidus. Erico earned a Ph.D. (2013) from the University of Georgia and a B.S from the University of Sao Paulo (2009). In 2012, Erico completed Singularity University’s graduate studies program in Mountain View, CA. Most recently Erico was a recipient of the 2020 40 under 40 award by the LED magazine and recognized by Produce Grower magazine in 2019 as Produce Pioneer for his contributions to the CEA industry. At GLASE, Erico works with academics and industry stakeholders to facilitate the development and implementation of new technologies aimed to improve CEA food production sustainability. At Candidus, Erico is leading the development and implementation of new lighting control technologies to increase greenhouses lighting energy use efficiency and maximize operations profitability.

Erik Runkle
