Emma Shtivelman, PhD

Chief Scientist

Emma Shtivelman is a molecular and cell biologist with extensive experience in cancer biology. She has in-depth understanding of cancer signal transduction and metabolism, cancer models in vitro and in vivo, target and drug discovery and validation, assay development, and preclinical research. She has technical expertise in numerous modern methodologies employed to understand the molecular basis of human malignancies and advance preclinical and clinical research.

Emma received her PhD in molecular biology from the Weizmann Institute of Science where she identified the fused transcript between two cellular genes, BCR and ABL in chronic myelogenous leukemia (CML), the first demonstration of an oncogenic gene product derived from a chromosomal translocation. As a postdoctoral fellow at the University of California, San Francisco (UCSF), she characterized the molecular consequences of chromosomal translocations in Burkitt lymphoma and identified gene products relevant to the pathogenesis of neuroblastoma.  She worked at Systemix on establishing a novel SCID-hu metastasis model to enable the in vivo analysis of human tumor metastasis. She continued her research activity at the UCSF Cancer Center analyzing deregulation of signal transduction pathways in human cancer and the molecular underpinnings of metastatic progression. Before joining Cancer Commons, Emma worked at BioNovo, Inc., researching new drugs that selectively disrupt metabolism of breast and pancreatic cancers by targeting their metabolic preferences.


Kalpana Kannan, PhD

Cancer Commons Scientist

Kalpana Kannan, PhD, is a molecular biologist by training with extensive interest in cancer genomics and cancer signaling pathways. She received her PhD in Biochemistry from Texas A&M University, where she defined the components of the plant telomerase ribonucleoprotein complex. As a postdoctoral associate at Baylor College of Medicine, she was interested in understanding the changes in the transcriptome in patient tumors. This led to the identification of novel gene fusions in high-grade serous ovarian cancer that mainly target the PI3K/AKT signaling pathway. Kalpana also identified chimeric RNAs in prostate cancers that are promising non-invasive urine biomarkers. At the Helen Diller Cancer Center at UCSF, she continued to focus on cancer research. She developed CRISPR/Cas9 tools for genome-wide screens in breast cancer cell line models as well as studied the drug sensitivity of certain mutations found in metastatic breast cancer patients. Before joining Cancer Commons, Kalpana worked briefly at a start-up to develop a clinical-grade next generation sequencing platform for genetic cancer testing.


Amanda Nottke, PhD

Cancer Commons Scientist

Amanda Nottke, PhD, is a molecular biologist and corporate strategist, with a longstanding interest in oncology and scientific communication. She has particular expertise in genetics and molecular pathways, targeted therapies, and immunotherapies, as well as the latest and most promising therapies in brain, breast, and lung cancers. She also specializes in risk assessment for early stage cancers, e.g., how to maximize benefit with least risk of side effects from unnecessary treatments.

A graduate of University of Oregon, Amanda worked as a research technician at OHSU for 2 years, before starting her PhD at Harvard University in 2005. While at Harvard, she defined a novel role for a histone demethylase enzyme in meiotic DNA damage repair – an enzyme that has since been implicated in several forms of cancer including leukemias. She completed her PhD in 2011 and then worked as a management consultant with Monitor Group, focusing on pharmaceutical and life sciences clients. Her oncology projects at Monitor and subsequently Blue Matter Consulting included drug launch strategies, brand planning, international expansion strategy, and franchise strategy. She was recruited to Roche Genentech as a Strategy Lead for their cancer immunotherapy franchise, and worked there for over a year before leaving to join Cancer Commons as an ASK Scientist and member of the Product Team.
