Our Affiliations

Dr. Arboleda

Dr. Valerie Arboleda is an Assistant Professor of Pathology and Lab Medicine at the David Geffen School of Medicine at UCLA. Dr. Arboleda graduated from the UCLA Medical Student Training Program (MSTP) with a Ph.D in Human Genetics and an MD in 2014. She went on to complete residency training in clinical pathology with an emphasis in molecular genetic pathology in the Department of Pathology and Laboratory Medicine at UCLA.

Dr. Russell

Dr. Bianca Russell is an Assistant Clinical Professor in the Department of Pediatrics and Division of Genetics. She obtained her medical degree from the University of California, Irvine and completed her combined pediatrics and human genetics residency and metabolic training at the Cincinnati Children's Hospital. Dr. Russell sees general genetics, cancer, and metabolic patients in Westwood and San Luis Obispo in-person and through telemedicine.

Dr. Weksberg

Dr. Rosanna Weksberg is a Professor of Paediatrics and Medical Genetics at The Hospital for Sick Children (SickKids) and University of Toronto. Dr. Weksberg’s current research focuses on the epigenetic basis of normal human development and the identification of epigenetic alterations associated with human disease, especially for growth and neurodevelopmental disorders. Dr. Weksberg is an Associate Editor for the American Journal of Medical Genetics and Frontiers in Genetics.

The Arboleda Lab at UCLA

Dr. Valerie Arboleda is the Principal Investigator of the Arboleda Lab. She is also a Physician-Scientist and Assistant Professor in the Departments of Human Genetics and Pathology at the David Geffen School of Medicine at UCLA. 

The Arboleda Lab at the University of California, Los Angeles (UCLA) is a research laboratory that leverages genomic tools to understand the molecular mechanisms of genes that are altered in human disease. Using a multidisciplinary approach, our goal is to investigate how different types of genetic changes affect the genetic and molecular profiles of cells and identify therapeutic targets for clinical diseases. 

One key focus of the Arboleda Lab is the study of genetic syndromes that occur due to rare pathogenic mutations in genes that are important for chromatin remodeling (also known as chromatin modifiers). In particular, the Arboleda Lab focuses on the ASXL genes and KAT6 genes, which encode proteins that regulate gene expression and chromatin structure.
