Research Focus :
  • Genetic epidemiology of breast and ovarian cancers
  • Etiology of prostate cancer in young men
  • Cancer etiology and outcomes - molecular and genetic aspects
  • Environmental factors and risk of developing breast cancer

My research is primarily focused on identifying genes and environmental stressors that predispose to disease and that cause disease progression. To perform this research, I have established collaborations with researchers around the world. Current studies in my laboratory are on breast, ovarian and prostate cancers and celiac disease. The hope is that this knowledge can be used to design both preventive and therapeutic strategies, and to identify at risk individuals for preventive strategies.

For breast and ovarian cancers, we are investigating reproductive and lifestyle factors including hormone replacement therapy, smoking and prophylactic surgeries and genetic factors that may interact with these lifestyle exposures for risk of developing cancer or disease progression once the cancer develops. For prostate cancer, we are investigating whether men diagnosed with prostate cancer at a young age have different underlying etiologies than men who are diagnosed at an older age. For celiac disease, we are investigating whether specific genes affect degree of symptoms and development of other autoimmune diseases in celiac disease cases and their relatives.

Genetic epidemiology of breast and ovarian cancers in women carrying BRCA1 and BRCA2 mutations

Since the discovery of BRCA1 and BRCA2 genes, we have been studying women and their families who carry deleterious mutations in these genes. The primary objectives of our research are to identify genetic and lifestyle factors that modify risks of developing cancers and that affect disease-free survival in those women who develop cancer. We hope this information can be used to assist in individual risk assessment, and to identify women to target for prevention/treatment strategies.

Do you have an alteration in a breast cancer gene?

You could be part of a solution for future generations. Researchers at City of Hope are seeking participants for a research study of breast and ovarian cancer. This research is funded by the National Institutes of Health.

Who is eligible to participate?

Any woman over the age of 18 who has tested positive for a BRCA1 or BRCA2 alteration that increases their risk of developing breast or ovarian cancer is eligible to participate regardless of whether or not she has been diagnosed with any type of cancer.

What do I have to do if I participate?

Participants will be asked to donate a sample of blood and complete a health and family history questionnaire. There is no cost to participate. Participants will be compensated $25 for their time to complete the questionnaire and provide a blood sample.

Who do I call if I am interested in participating or if I have questions?

Breast Cancer Risk in Hispanic Women Research Study

Researchers at City of Hope are seeking Hispanic women who have not been diagnosed with cancer (basal cell carcinoma of the skin is okay) to participate in a research study. The purpose of this research study is to identify underlying causes of breast cancer. Our hope is that it will provide clues to develop preventive strategies and individualized treatment plans in the future.


  • Ages 35 to 85
  • Hispanic ethnicity
  • No cancer history (basal cell carcinoma of the skin is okay)


  • Complete a questionnaire
  • Donate a sample of blood


  • You will receive a $25 gift card for your participation in this study
