Nadine Hempel, Ph.D.

Principal Investigator

Associate Professor of Medicine, Division of Hematology/Oncology

Nadine received her PhD in Pharmacology from the University of Queensland in Brisbane, Australia, where she studied the regulation of sulfotransferase enzymes under the mentorship of Drs. Mick McManus and Masahiko Negishi (NIEHS, USA). During her post-doctoral training in the labs of Dr. Gerard Blobe at Duke University, and Dr. Andres Melendez at Albany Medical College, Nadine developed interests in tumor metastasis, focusing on TGF-beta signaling in ovarian cancer, and the role mitochondrial reactive oxygen species and superoxide dismutase SOD2 play during metastasis. Nadine started her independent lab at the SUNY College of Nanoscale Sciences and Engineering with NCI K99/R00 funding, and subsequently moved to the Penn State College of Medicine in 2015. In 2021 her laboratory relocated to the Hillman Cancer Center at the University of Pittsburgh, where she joined the Cancer Biology Program and Women’s Cancer Research Group.

 

Zaineb Javed
Graduate Student
Zaineb received her Bachelor of Science in Biology from Lahore University of Management Sciences in Pakistan. Zaineb joined the lab in 2019 and is a PhD candidate in the Biomedical Sciences graduate program at the Penn State Hershey College of Medicine. Her research projects focuses on mitochondrial fission and fusion dynamics, and the role of the fission protein Drp1/DNM1L in ovarian cancer. Zaineb’s publications include: PMC8899553, PMID:35259492.
Amal Elhaw
Graduate Student
Amal received her Bachelor degree in Pharmacy and Masters in Clinical Pharmacy from Tanta University in Egypt. Amal joined the lab in 2020 and is a student in the Biomedical Sciences Graduate Program at Penn State. Amal is interested in studying novel adaptations related to survival in response to anchorage independence and potential interplay with drug resistance mechanisms in ovarian cancer.
Amal’s publications include: PMID:35259492.
Priscilla Tang
Graduate Student
Priscilla received her Bachelor of Science from the University of California Irvine, after which she spent several years as a researcher in biotech companies before joining the Penn State Biomedical Sciences graduate program. She joined the Hempel lab in 2020. Her PhD dissertation studies focus on how the SIRT3/Sod2 redox signaling axis contributes to early adaptations during ovarian cancer metastasis. She has contributed to work demonstrating the translational regulation of SOD2 in tumor cells in response to anchorage-independence.
Priscilla’s publications include: PMID:35259492.
Caroline Chang, DVM
Veterinary Resident
Caroline received her Doctor of Veterinary Medicine from the North Carolina State University and is currently a veterinary resident in the Laboratory Animal Medicine Residency Program in the Department of Comparative Medicine at Penn State Hershey. Her project focuses on the in vivo role of GPX3 in tumor progression.
