The Division of Infectious Diseases at Mayo Clinic's campus in Arizona is staffed by specialists dedicated to patient care, research, and education in their daily practices.

From the program director

Sandhya Nagarakanti, M.B.B.S., M.D.Mayo Clinic training programs foster a diverse and inclusive culture of lifelong learning, create a conducive environment to deliver outstanding patient care in multidisciplinary teams, and provide unparalleled opportunities for research and education.

Mayo Clinic School of Graduate Medical Education (MCSGME) is home to more than 270 individual training programs that cover every medical and surgical specialty across the three Mayo Clinic campuses. MCSGME oversees the largest number of ACGME-accredited programs in the United States. Learn more about why residents and fellows choose Mayo Clinic.

Mayo Clinic's Arizona campus was established in 1987. Since our inception, we have grown into a tertiary care institution with more than 500 physicians, along with more than 220 residents and fellows.

Our fellowship has been designed to provide an exceptional learning experience in all aspects of clinical infectious diseases. Our faculty members have years of experience training students, residents, and fellows. Several are world-renowned for their research and expertise and have many active and ongoing clinical trials. You have the opportunity to participate in the three-site case conferences in which faculty and fellows from the three Mayo Clinic campuses present and discuss challenging cases. Weekly infectious diseases core curriculum lectures are delivered by renowned faculty from all three Mayo Clinic sites.

Other valuable offsite rotations include an HIV continuity clinic at Valleywise Healthcare Center, pediatric infectious diseases at Phoenix Children's Hospital, and Maricopa County sexually transmitted infections and TB clinics. You have access to patient medical records across Mayo Clinic's campuses to facilitate coordinated patient care and collaborative clinical research. Opportunities for elective rotations and ample time for research will result in a well-rounded educational experience.

At the end of your fellowship, I'm confident that you will be fully equipped to pursue your chosen career path in infectious diseases. We look forward to hearing from you soon.
