Species invasions are increasing worldwide and are impacting populations, communities, and ecosystems. Non-native species that are ecosystem engineers, such as earthworms, may be particularly likely to have large impacts due to their ability to modify both biological and physical characteristics...

All species’ ranges are the result of successful past invasions. Thus, models of species’ invasions and their failure can provide insight into the formation of a species’ geographic range. Here, we study the properties of invasion models when a species cannot persist below a critical population...

Analysis and interpretation of next generation sequencing data has posed a significant challenge to researchers, especially to those who are not equipped with expertise in bioinformatics. In this thesis, I investigated three different biomedical questions using NGS and bioinformatic approaches,...

Predictions for climate change include movement of temperature isoclines up to 1000 meters per year, and this is supported by recent empirical studies. This paper considers effects of a rapidly changing environment on competitive outcomes between species. The model is formulated as a system of...

Esophageal squamous cell carcinoma (ESCC) is one of the most lethal cancers worldwide, largely due to a high frequency of tumor invasion/metastasis, chemoresistance and recurrence. In this study, we explored from different perspectives the molecular mechanisms behind these aggressive features of...

The question how aquatic populations persist in rivers when individuals are constantly lost due to downstream drift has been termed the “drift paradox.” Recent modeling approaches have revealed diffusion-mediated persistence as a solution. We study logistically growing populations with and...

Recent literature on plant population spread advocates quantification of long-distance dispersal (LDD). These estimates could provide insights into rates of migration in response to climate change and rates of alien invasions. LDD information is not available for parameterization of current...
