As a biologist, I am broadly interested in the ecology and evolution of all life on Earth, particularly how natural selection has shaped the evolution of millions of “endless forms most beautiful”. As a natural historian, I am broadly interested in patterns and trends that characterize the history of such remarkable life on Earth, particularly patterns that we know to be repeated or unique, and historical transitions that we know to be reversible or irreversible. Knowledge of evolutionary history is extremely empowering, has important real-world applications, and has predictive potential.

In attempt to understand the evolution of biodiversity and the millions of ecological functions that biodiversity sustains, I have most often assumed a macroevolutionary perspective, i.e., at or above the species level (although microevolutionary studies or studies that combine macro- and microevolutionary investigation are equally valuable!). I have to date spent most of my career trying to understand biodiversity through research on flowering plants, particularly the species-rich (>4,000 spp.) and morphologically diverse tropical plant family Acanthaceae. More recently, I have developed research interests in lichenology, particularly here in the United States where amazingly, some 230 years after the Bartram’s first traversed the Southeast, we still know so incredibly little about these organisms that a new species may be lurking under the rock nearest to you (see Tripp & Lendemer 2012)! In addition to research on Acanths and lichens, I have maintained long-term interest in the flora of the tepui highlands in Western Guyana, where I have participated in or co-led numerous collecting expeditions to remote locations in effort to provide baseline plant biodiversity information for these highly endemic ecosystems
