Dr. Kristen Wigby is a clinical geneticist and dysmorphologist at Rady Children's Hospital-San Diego and an assistant professor in the Department of Pediatrics at UC San Diego. She is the co-founder and medical director of Rady Children's Precision Medicine Clinic and the medical director of the Rady Children's Multidisciplinary Autism Clinic at Torrey Hills. She also evaluates patients in the Turner Syndrome Clinic and the Neurometabolic Clinic.

In her own practice, Dr. Wigby evaluates children with birth defects or those who are suspected of having a genetic problem or syndrome. Her philosophy of care is to partner with children and families throughout their journey from diagnosis through treatment, and to empower these children and families.

Dr. Wigby earned her medical degree from the University of California, San Diego School of Medicine and received the George G. Glenner Award for compassionate care and research achievements. She completed her pediatric residency at the University of Colorado, Denver and the Children's Hospital of Colorado. Upon completing her genetics fellowship at UC San Diego and Rady Children's Hospital, she joined the UC San Diego faculty.

Along with her clinical work, Dr. Wigby is a clinical investigator at the Rady Children's Institute for Genomic Medicine. Her research focuses on the delineation of rare disorders and clinical implementation of genomic sequencing across a variety of pediatric populations, including neurodevelopmental disorders and congenital anomalies. She also studies clinical features in females with Trisomy X and was a leader in developing guidelines for the multidisciplinary care of females with Trisomy X.

When not working, Dr. Wigby enjoys spending time with her family, hiking and attending UCLA sporting events.
