I have a strong interest in global cancer epidemiology and control. My major research focuses on the epidemiology of childhood cancers within cohorts of children from the United States and Scandinavia, with an emphasis on environmental and occupational causes of cancer as well as maternal and paternal health behaviors and the perinatal environment. Our group has several ongoing projects which examine the risk of cancer among California’s diverse populations.
Childhood Cancer in Relation to Parental Occupational Exposure to Chemical and Other Agents
I lead the Parental Occupation and Childhood Cancer (POCC) Study, an international effort that integrates data from large prospective databases in Denmark with cancer registry data. The overarching objective of this study is to address hypotheses of exposure to environmental agents in childhood cancer etiology, using validated job-exposure matrices (JEMs) developed by Danish occupational hygienists. This project includes over 6000 cancer cases, and we are able to additionally use data from the Danish Medical Births Registry to address questions of gestational risk factors.
Maternal Comorbidities, Prescription drug use in pregnancy, and Childhood cancer (COMPAC): a record linkage study in Denmark
I am PI of a large-scale study of childhood cancer among Danish children which utilizes information from large medical and pharmaceutical databases to examine the risk of childhood cancers from maternal comorbid health conditions and prescription drug use during pregnancy.
Environmental Health Tracking of Childhood Cancers
Our group has several projects which use California Cancer Registry records of 11,000 childhood cancer cases, linked to California birth records, to examine the risk of cancer related to perinatal exposure to traffic-related air pollution, air toxics, pesticides, and other environmental as well as gestational risk factors.
Smoking and Embryonal Tumor Study
Our group is starting a new project which will conduct broad metabolomic profiling of newborn blood spots. We aim to examine whether nicotine and cotinine differ in blood spots between retinoblastoma cases and controls, and also to examine a variety of metabolites in relation to cancer risk.
I joined UCLA in 2009 and am an Associate Adjunct Professor of Epidemiology and a member of the Jonsson Comprehensive Cancer Center. Prior to coming to UCLA I completed a postdoctoral fellowship at the International Agency for Research on Cancer, an agency of the World Health Organization. I am a member of the Childhood Leukemia International Consortium, the Children's Oncology Group, and the Brain Tumor Epidemiology Consortium.
