About Tobias Boehme, PhD

Dr. Boehme’s background is in physics and oceanography. Today he is involved in several research projects in the field of holographic detection of algae and is focused on developing new and innovative algae devices as well as instrument installation and integration for bbe Moldaenke and is a frequent speaker on the topic of HAB.

About Detlev Lohse, PhD

Dr. Lohse studied biochemistry at the University of Hannover, Germany, and received his Ph.D. from the University of Düsseldorf in 1986. He spent more than ten years in fundamental research specializing in plant biochemistry. For the last 22 years, Detlev’s focus has been on knowledge transfer regarding photosynthetic processes and algal pigments.

Past Webinars

Best Way to Perform Light Response Curves?
The right protocol depends on the information you’re looking for! | 10.15.20

Presented by James Bunce, PhD

What important factors should you consider when purchasing a leaf gas exchange system? Find out more about the popular CIRAS-3, the fastest, most accurate portable photosynthesis system on the market for high-level research.

About Dr. Bunce

Dr. James Bunce built his first photosynthesis system as a graduate student 48 years ago and has been performing leaf gas exchange measurements ever since.

He has 40 years of research experience with the USDA Agricultural Research Service in Beltsville, Maryland as an environmental plant physiologist. His focus has been on photosynthesis, stomatal conductance, and plant water relations and their response and acclimation, in the context of plant adaptation to the environment, most recently adaptation to the global change factors of rising carbon dioxide concentration and temperature.

Small System Volume: Size Does Matter. | 09.16.20

Presented by Sinisha Ivans, PhD

What important factors should you consider when purchasing a leaf gas exchange system? Find out more about the popular CIRAS-3, the fastest, most accurate portable photosynthesis system on the market for high-level research.

About Sinisha Ivans

Sinisha Ivans is a Technical Sales Engineer at PP Systems, Inc. He provides high-level technical and application-related expertise and support to existing customers. He also focuses on establishing and building relationships with customers worldwide – helping them achieve their research needs. His research interests have included observing closed path systems across the Mountain West to determine water characteristics and CO2 fluxes of sagebrush, as predominant native vegetation of the region. He holds a Ph.D. in Civil and Environmental Engineering from Utah State University.

Red, Green & Blue: Misconceptions About the Photosynthetic Efficacy of Different Light Colors | 07.23.20

Presented by Marc van Iersel, PhD

Because of the relatively low leaf absorptance of green light, it is commonly believed to be inefficient in driving photosynthesis. Dr. Marc van Iersel, from the University of Georgia, will discuss how A/Ci and light-response curves were used to develop a more nuanced understanding of the interactive effects of light intensity and color with regard to photosynthesis.

About Dr. van Iersel

Dr. Marc van Iersel has been with the University of Georgia’s Department of Horticulture since 1995, where he now holds the Dooley professorship.

His research focuses on cost-effective supplemental lighting technologies in greenhouses and vertical farms.

He is the director of project LAMP, a $5M, US-based research project that brings together plant scientists, engineers, and economists to develop profitable supplemental lighting strategies.

In 2017, he co-founded Candidus, Inc. to help bring novel lighting strategies to the greenhouse industry.

Dr. van Iersel has published 130+ scientific papers and has given invited lectures about his research around the world, including in Italy, Spain, Taiwan, Kenya, Canada, Chile, and Brazil.

What, Why & How: A/Ci? | 06.24.20

Presented by James Bunce, PhD

Learn the purpose of performing non-steady-state A (Assimilation) vs. CI (Intercellular CO2) curves and how to perform and process them quickly.

About Dr. Bunce

Dr. James Bunce built his first photosynthesis system as a graduate student 48 years ago and has been performing leaf gas exchange measurements, including many A/Ci curves ever since.

He has 40 years of research experience with the USDA Agricultural Research Service in Beltsville, Maryland as an environmental plant physiologist.  His focus has been on photosynthesis, stomatal conductance, and plant water relations and their response and acclimation, in the context of plant adaptation to the environment, most recently adaptation to the global change factors of rising carbon dioxide concentration and temperature.

He has recently published two research papers utilizing the technology and technique presented in this webinar: Three Methods of Estimating Mesophyll Conductance Agree Regarding its CO2 Sensitivity in the Rubisco-Limited Ci Range and Variation in Responses of Photosynthesis and Apparent Rubisco Kinetics to Temperature in Three Soybean Cultivars.
