Meet Dr. Andrey Rubin, a Vaadia-BARD postdoctoral fellow currently conducting his research at Prof. Gilbertson’s lab at Duke University.
What is the main focus of your research?
“My research at Duke University focuses on preventing microbiological contamination in hydroponic systems using a photocatalytic material called carbon nitride (CN). When activated by light, CN generates reactive species (radicals) that can effectively eliminate bacterial contamination while introducing minimal toxic materials into the system. This approach can help reduce biomass loss caused by contamination, support farmers by lowering the effort required for system disinfection, extend the usable lifetime of the hydroponic system, and decrease the reliance on toxic chemicals.”
What got you interested in your area of research?
“This is my first time working with hydroponic systems, and I find it very exciting. In recent years, hydroponics has gained increasing attention and adoption, particularly as a means to support small-scale agriculture in urban areas. This approach represents a highly promising direction, offering sustainable and efficient food production.”
What are your plans after your fellowship?
“I am currently applying for positions as a principal investigator and aim to continue my research in environmental engineering, with a focus on applications in urban environments.”
What tip would you give someone beginning their postdoctoral research?
“The early stages of research are often the most challenging. You need to adapt to a new environment, and progress can be slow and sometimes frustrating. However, over time, things begin to move forward. Research is a long-term journey, and steady progress will come. It is also important to take breaks along the way and invest time in family and friends.”
