Bernard Grodzinski

Bernard Grodzinski is a retired Professor and Adjunct Professor in Plant Agriculture at the University of Guelph. He specializes in plant physiology, particularly photosynthesis and carbon partitioning, with a focus on applications in controlled environments like space agriculture and commercial greenhouses. His research integrates plant biology, environmental science, and engineering to optimize plant productivity.

Dr. Grodzinski holds a Ph.D. from York University and is affiliated with the SALSA (Space and Life Support Agriculture) team, collaborating with NASA’s Kennedy Space Centre and the European Space Agency (ESA). His work addresses challenges in sealed environments, including CO₂ scrubbing, O₂ production, and water purification using plants as bioregenerative systems.

Key research themes include: (1) Photosynthetic efficiency under varied light conditions, (2) Non-invasive disease detection via gas exchange profiling, and (3) LED lighting optimization for crop production. He has pioneered methods to quantify carbon export and growth using whole-plant gas exchange analysis.

Recent publications emphasize LED spectral effects on tomato and cucumber yields, circadian rhythm entrainment, and thylakoid structure-function relationships. His interdisciplinary approach bridges plant biology with aerospace and agricultural engineering.

Dr. Grodzinski has led grants exploring light interception strategies, hydroponic disease control, and plant stress responses. The SALSA team’s work supports both space missions and terrestrial greenhouse industries through sustainable crop systems.

He is a co-developer of the Leafweb dataset and has contributed to advancements in 3D plant phenotyping using computer vision. His legacy includes over 150 peer-reviewed publications and innovations in controlled environment agriculture.
