I am a research associate with a background in plant ecology and physiology. My objective is to further our knowledge of ecological mechanisms and patterns of plant regeneration from seeds. This research serves to inform conservation strategies, habitat restoration, and efforts to mitigate environmental impacts.
Additionally, I am interested in using image analysis techniques to improve our ability to describe the morphological characteristics of seeds, and to develop more effective tools for seed identification and quality sorting.
