Eric Brenya, Ph.D.

Dr. Eric Brenya is a plant molecular biologist who studies how plants sense environmental signals and translate them into changes in growth, development, and stress tolerance. He joined Trinity University after six years as a postdoctoral research associate at the University of Tennessee, Knoxville, where he worked in the laboratory of Prof. Brad Binder. He earned his bachelor’s degree in Ghana before receiving an Australia Awards for Africa Scholarship to pursue a Master of Philosophy in Plant Science at the University of Queensland under the supervision of Prof. Jimmy Botella. He subsequently earned his Ph.D. in Molecular Plant Science from the Hawkesbury Institute for the Environment at Western Sydney University, Australia, under the supervision of Prof. Christopher Cazzonelli. His doctoral research examined how epigenetic changes influence plant responses to mechanical stress and contribute to plant phenotypic plasticity.

During his postdoctoral research, Dr. Brenya found that exposing germinating Arabidopsis thaliana seeds to ethylene in darkness before transferring them to light can promote growth and stress tolerance. His work identified the enzyme cytosolic invertase as an important component of this response and revealed connections between early ethylene signaling, chloroplast biogenesis, photosynthesis, and metabolism.

At Trinity University, his research builds on these findings by investigating how ethylene priming during seed germination shapes plant development and responses to environmental stress. His lab examines how transient ethylene treatment alters carbohydrate metabolism, chloroplast biogenesis, cellular signaling, and gene expression, and how these changes influence plant growth and resilience long after the initial treatment. His broader research interests include plant–microbe interactions, photosynthesis, chloroplast biology, stress physiology, and mechanobiology. Using genetics, molecular biology, and cell biology, his lab seeks to understand how plants integrate hormonal and environmental signals to coordinate growth, development, and immunity. Dr. Brenya is also passionate about involving undergraduate students in research. In his lab, students develop the critical-thinking skills to ask meaningful scientific questions, design experiments, analyze data, and link molecular mechanisms to plant growth and responses to the environment.
