Dr. Srougi earned her B.S. in Biology from the University of Toledo in 2001, and her Ph.D. in Pharmacology from Case Western Reserve University in 2007. Her graduate work, under the supervision of Dr. David A. Boothman, focused on the cellular mechanisms of a novel cancer chemotherapeutic agent beta-lapachone with an emphasis on the DNA damage response. Following completion of her doctoral studies, she completed a post-doctoral fellowship with Dr. Keith Burridge at the University of North Carolina at Chapel Hill where she studied the regulation of the Rho family of small GTPases after DNA damage. Dr. Srougi joined the Biotechnology Program at North Carolina State University in 2011.
My research interests are to understand how cancer cells acquire resistance to DNA damaging radio- and chemotherapeutic agents. I am particularly interested in uncovering how the Rho family of GTPases modulate the cellular response to genotoxic stress. Elucidating these signaling pathways may have significant therapeutic implications in the current treatment of cancer.
Questions Currently Under Investigation with Undergraduates:
1. How does loss of the DNA damage repair protein ATM affect Rho GTPase function?
2. Do agents that cause different types of DNA damage elicit similar pathways of Rho GTPase activation?
3. How are the guanine nucleotide exchange factors (GEFs; activators of Rho GTPases) regulated after DNA damage?
In addition to my laboratory research, I am also interested in the study of teaching and learning. My pedagogical research includes finding ways to improve student scholarship in the biomedical sciences with a focus on developing student-centered activities and inquiry-based laboratories. One of my recent publications describes a new research-based laboratory course on signal transduction.
