Dr. Ochoa is an Associate Clinical Professor of Dermatology at the Keck School of Medicine USC. She recently joined the Department of Dermatology at Keck Medicine of USC after 10 years of practice at the UCLA Division of Dermatology.

Dr. Ochoa is a member of the American Academy of Dermatology, the Society for Investigative Dermatology and California Dermatologic Society. Dr. Ochoa sees patients in the private practice settings at Keck Medicine of USC – Beverly Hills, and Healthcare Consultation Center II on the USC Health Sciences Campus, and participates in the care of the uninsured at the LAC+USC Medical Center. She serves as the Director of the Hansen’s clinic.

Dr. Ochoa provides dermatology services for the diagnosis and treatment of a broad range of general skin diseases such as acne, eczema, skin cancer and psoriasis, among others. Her clinical and research interest center around infectious diseases of the skin, including the diagnosis and treatment of patients with skin manifestations of HIV, tropical dermatology (skin infectious diseases acquired abroad) and sexually transmitted diseases.

Dr. Ochoa has a special research interest in the immunologic mechanism of the host response in infectious diseases of the skin.
