Postdoctoral Fellow, Dr. Zijlstra’s Lab, Vanderbilt University
Dr. Arnold started as a graduate student in the laboratory of Rolf Brekken at UT Southwestern, where she studied the role of the tumor microenvironment in cancer progression and metastasis. Her specific research emphasis was then, and now, on molecular mechanisms that control tumor progression.
Dr. Arnold is currently a postdoctoral research fellow in the laboratory of Dr. Zijlstra at Vanderbilt University where her projects focus on tumor cell adhesion, migration and metastasis. She spearheads the translation of these mechanistic findings to the development of clinically relevant biomarkers. The current focus is on the clinical relevance of a cell adhesion molecule, ALCAM, and the mechanism by which is controls motility.
