Dr Rafal Gutaker is a plant evolutionary scientist specialising in ancient genomics, environmental change, and the long-term trajectories of crop diversity. He completed his PhD in Plant and Environmental Science at the University of Warwick (UK) and subsequently gained more than six years of postdoctoral experience at the Max Planck Institute (Germany) and New York University (USA). He then served for five years as a research leader at the Royal Botanic Gardens, Kew (UK).
Across his career, Dr Gutaker has established himself as a leading expert in plant ancient genomics, pioneering innovative methods and analytical approaches that have advanced the field. He has also integrated comparative genomics with ecological and environmental perspectives, most notably through his research on rice–environment interactions over the past six thousand years, which has generated key insights into how environmental change shapes the geographical distribution of genetic diversity.
Dr Gutaker currently leads major research projects on the genomics of rice history and the domestication of millets, and supervises several fellowship projects examining long-term changes in plant diversity.

Plants and fungi hold essential clues to many of the natural world’s most pressing challenges, yet much remains unknown about the traits that enable them to survive and thrive across diverse environments. A species’ suite of traits reveals how it has adapted to particular conditions and how resilient it may be to future change. Deepening our understanding of these characteristics—how they function and how they have evolved—will strengthen our ability to conserve plants and fungi both within and beyond their native habitats. It will also help us identify species and bioactive compounds that can be used sustainably and equitably for the benefit of society.
The evolutionary history of sex determination in plants varies from one species to another. In the Lauraceae family, the closely related genera Litsea and Lindera have developed dioecious sexual systems in some species; however, it is unknown whether these two genera share similar sex-determination mechanisms due to an ancient evolutionary origin of sex differentiation. RBG has 399 records of Litsea cubeba (mountain pepper) and 112 records of Lindera communis; both species have chromosome-level genomic information. In this project, the intern will investigate these herbarium samples and select specimens for targeted sequencing or whole-genome sequencing; these results will provide a foundation to unravel the mystery of sex determination in the Lauraceae family.

Plants in the genus Vigna include a wide range of important legume crops—such as mung bean, adzuki bean, cowpea, and rice bean—valued for their flavour, nutritional qualities, and global significance. Although key genomic resources have been developed for these species and their domestication histories are increasingly well understood, the full extent of genetic diversity across cultivated Vigna and their wild relatives remains under-explored.
RBG Kew holds one of the world’s most extensive collections of plant diversity across its gardens and herbarium, including more than 7,000 Vigna specimens. In this project, the intern will examine this collection, identify materials that address gaps in existing seed bank holdings, and generate genomic sequences to deepen our understanding of Vigna genetic diversity.
