My research interests span several areas…

Invasive species management

My current dissertation research focuses on the detection of invasive species in U.S. forests. Invasive species pose a serious environmental and economic problem. The annual economic loss amounts to billions of dollars in the U.S. alone. After habitat destruction, invasive species pose the second greatest threat to global biodiversity.

Postsecondary education and student finances

Postsecondary education plays a crucial role for both individuals and society. Many worry that rising tuition costs reduce access to already underrepresented groups in higher education. Those who take the risk and finance their education through loans and jobs face persistence issues. And those who successfully complete their degrees shoulder the burden of substantial loans. The first step in this research involves understanding the demographics of students enrolled in postsecondary education. The next step delves further into the data to identify the key factors affecting decisions to borrow, the borrowing levels, the impact of student debt burdens and the deterrent effects of rising tuitions on various subpopulations of students.

Addressing environmental and development concerns

Environmental concerns are deeply entwined with development and poverty issues facing many people around the world. One area can not be addressed without considering the other. Creative strategies are needed to address these dual challenges. One such innovative idea, Savannas Forever, aims to conserve ecosystems by increasing interaction between all stakeholders affected by, and affecting, the African savannas.
