Research Interest

We study the development of biosensors for agriculture and food where we use micro and nanoscale technologies. The goal is to develop sensors that will be integrated on the plant (i.e. leaves, stem, rhizosphere, etc.) for early detection of various parameters that are the key factors in the food chain. 


The goal to develop, generate and evaluate a radical multi-functional plant-based biosensor for biotic and abiotic stresses encountered by different crop plants in agricultural settings. This project is based on years of research in both plant sciences and electrical and optical engineering, culminating in the understanding that the future of functional sensing in agriculture depends on amalgamated technologies and biosensors comprised of a biological and engineering component working in concert to achieve the most biologically relevant and accurately measurable signal for effective precision agriculture. We apply synthetic biology, genetic, gene editing techniques in our research.


The second research subject in the laboratory interest is the study of the induction of plant innate immunity: Plant resistance against disease involves inducible defense mechanisms (innate immunity). Our research focuses on understanding the signal transduction pathway by which a fungal protein induces innate immunity in tomato and tobacco plants. We address this question from several angles: We use a genetic approach to isolate novel genes from tomatoes that are involved in the induction of innate immunity. Using biochemistry, genome editing, and cell biology techniques, we study the signaling process that leads to the induction of innate immunity
