Agricultural Informatics

I am currently involved in the development of methods that leverage artificial intelligence to tackle agricultural issues. One example is the identification of significant agricultural organisms through image analysis and the detection of diseases and pests on crop leaves. Furthermore, I am working on techniques to predict the severity of future disease and pest outbreaks by utilizing open data from past outbreaks.

Plant Science & Bioinformatics

I am actively involved in the analysis of plant RNA-seq data to gain a deeper understanding of gene function, and I am also dedicated to developing bioinformatics methods and tools specifically designed for this purpose. One of my primary research focuses lies in the realm of allopolyploid plants, which are formed through the hybridization of closely related species, such as wheat and bittercresses. Additionally, I am highly interested in analyzing RNA-seq data derived from viroids, which are the smallest known pathogens that infect plants.
