Program Coordinator, Biology Integration Institute

Content Detail

After completing her PhD in forest biology, Andrea joined the Arboretum to help it to establish the TREETIME Biology Integration Institute.

The Terrestrial Responses to Emerging Environments through Time, Integrated from Moments to Eons (TREETIME) Biology Integration Institute—part of a National Science Foundation initiative—is aimed at fostering collaboration and multidisciplinary research in confronting today’s toughest issues in tree biology. This endeavor mirrors Andrea’s belief that such challenges are too complex to be solved by a single discipline and that the most effective solutions occur when diverse perspectives and expertise are brought together.

Andrea also works to ensure that plant science is communicated effectively and meaningfully for both technical and non-technical audiences. Her research interests include ecophysiology, phenology, propagation, and biotechnology—particularly for the conservation of at-risk tree species. As such, in her role with TREETIME , Andrea has taken a strong interest in implementing the latest team science into the design process.

As a public horticulture undergraduate at Purdue University, Andrea was on the original team that created the university’s campus-wide Purdue Arboretum. After graduating with the highest distinction, she became The Purdue Arboretum’s first staff member. As its Collections Manager, she led all mapping, database, outreach, and teaching efforts for the organization.

Andrea went on to obtain an MS fellowship with the Longwood Graduate Program in Public Horticulture—a partnership between the University of Delaware and Longwood Gardens—where she researched bud-forcing and tissue culture for the conservation of threatened oak species. 

Following the completion of her MS, Andrea started work on a PhD in forest biology as a Fred M. van Eck Scholar. As part of this work, Andrea employed a multidisciplinary approach to evaluating the use of hybrids for restoring threatened tree species, with a particular focus on the butternut (Juglans cinerea).

Andrea has been instrumental in the design of the TREETIME Biology Integration Institute.
