My main research interest is on the consequences of population bottlenecks during domestication and breeding and habitat destruction, degradation, and fragmentation.  We use the tools of genomics and evolutionary ecology to preserve diversity of crop wild relatives and endangered species, and to understand adaptation to particular habitats.  Rooted into the strong tradition and commitment of Fairchild Tropical Botanic Garden for international collaboration and conservation, my studies have a strong field component that both test material under realistic conditions and develop strong relationships with developing world scientists in places such as Turkey, Ethiopia, India, and the Caribbean. Current work in my lab centers on the legume crops of the semi-arid tropics such as chickpea and pigeonpea, and on the endangered plants of Florida.  My laboratory is located at the University Park campus of Florida International University, while my students work at FIU, Fairchild, and around the world.

Research Themes and Active Research Projects

My research activities focus on understanding adaptation to habitats, and utilizing this information for agricultural improvement and conservation of rare species and habitats.  They link with the 80 year history of research and conservation of Fairchild.

Within these themes currently I have the following three Active Research Projects:

Domestication Genetics of Tropical Crops
During domestication strong population bottlenecks are thought to occur in many crop species due to strong selection on traits that crop plants require to perform well under agricultural conditions such as indehiscent fruits.  These strong bottlenecks can reduce genetic variability and the adaptive potential of crops for marginal or challenging agricultural conditions.  If we can find the genetic basis of domestication traits, we can return adaptive traits to our crops through breeding with wild relatives.  However, germplasm collections of many crop wild realtives are woefully inadequate and grossly undersample the full range of conditions that wild relatives can tolerate.  My lab works with chickpea, pigeonpea, and mangoes to understand the consequences of domestication and the ensuing population bottlenecks, and to expand and preserve wild relative diversity in germplasm collections.

 

Population genetics of Florida and Caribbean endangered species
Plants from Florida the Caribbean Islands are in the core of the educational, horticulture, and research activities of Fairchild and they are one of the main priorities of my laboratory.  In colonizing Florida from the Caribbean, many of our native plants underwent a severe population bottleneck.  We are examining genetic and morphological consequences of this bottleneck in the tropical species of Florida.  We have a particular focus on Pilosocereus cacti, but have also examined species of PSeudophoenix palms, the miccosuke gooseberry, and partridge peas.  We are keen to expand this work to a broader number of species.

Community genomics of salt tolerance in Medicago truncatula 
In collaboration with colleagues from the University of Southern Californa, UC Davis, and the Center for Biotechnology at Borj Cedria in Tunisa, we have resequenced the genomes of 40 individuals from saline and non-saline habitats in Tunisia, and examined the phenotypes of plants under several saline conditions in the greenhouse and field.   Association mapping will provide candidate genes for salt tolerance in this wild relative of alfalfa, which subsequent mutant analysis will verify for the long-term aim of improving crop salt tolerance.  [link to project website]
