Robert Clarke, PhD, DSc, FRS Chem, FRS Biol, FRSMed (UK)

Dr. Robert Clarke is an internationally recognized leader in breast cancer research whose work has shaped understanding of how hormones, growth factors, and related molecular pathways influence breast cancer development, progression, and treatment resistance.

His expertise spans estrogen and antiestrogen action, aromatase inhibitors, cell signaling, bioinformatics, drug resistance, signal transduction, and systems biology. He developed a series of hormone-resistant breast cancer models that are now widely used in the field, and he continues to advance new experimental models.

Dr. Clarke’s research integrates genomic, bioinformatic, translational, and experimental approaches to study breast cancer in both human and model systems. His recent work has identified a systems biology–based signaling network that regulates oncogenic and tumor-suppressive programs in breast cancer. This network connects cell-stress signaling, protein misfolding and the unfolded protein response, endoplasmic reticulum function, mitochondrial activity, and nuclear communication. Together, these processes help determine whether breast cancer cells grow, differentiate, die, or develop resistance to therapy through mechanisms such as apoptosis, ferroptosis, necroptosis, pyroptosis, and related forms of programmed cell death.

Dr. Clarke has led major multinational molecular medicine studies in breast cancer, collaborating with investigators at Mayo Clinic, the University of Edinburgh, and Virginia Tech. At Georgetown University, he directed the NCI-funded Center for Cancer Systems Biology from 2010 to 2016, and together with Dr. Subha Madhavan, led an NCI-funded in silico Research Center of Excellence from 2009 to 2014.

He has published more than 340 original papers, reviews, and book chapters, and has edited two books: Cancer Gene Networks, co-edited with Dr. Usha Kasid in 2017, and The Unfolded Protein Response in Cancer in 2019. He has also edited or co-edited special issues for Breast Cancer Research and Treatment and Cancer Metastasis Reviews.
