Maloof and Sinha analyzed the effects of various light environments on leaf development for both the wild and cultivated tomato species. Plant biologist Julin Maloof met fellow researcher Neelima Sinha while beginning his career at the University of California, Davis. Both interested in plant morphology and natural variation, the two first collaborated on a proposal more than six years ago and continue to work together to examine how plants thrive in disparate environments.
