Infectious Diseases Fellowship (Arizona)

Department and Faculty

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.

Some current areas of research being pursued by our faculty members with national and international recognition include:

  • Coccidioidomycosis
  • Fecal microbiota transplantation
  • Endocarditis
  • Cardiovascular device infections
  • Viral respiratory infections
  • Immunocompromised host infections
  • Transplant-associated infections
  • Basidiobolomycosis

Clinical laboratories

We also have an on-site, full-fledged state-of-the-art microbiology and serology laboratory led by Thomas E. Grys, Ph.D., in close collaboration with the world-famous Mayo Clinic Laboratories in Rochester, Minnesota. During inpatient rotations, you will lead weekly microbiology rounds during which stained specimens, cultures, and other pertinent samples from patients on the consult service are reviewed and discussed in detail.

Microbiology laboratory staff also challenge the team each week during rounds with "unknowns" — a very popular segment wherein culture plates, smear photographs, and other specimens are demonstrated while faculty and fellows compete to arrive at the correct pathogen. Others present at microbiology rounds, including the faculty member on the inpatient service, Dr. Grys, medical residents, students, lab technicians, and the lab supervisor.

Advisers and mentors

Faculty advisers are available to provide comprehensive educational advice and personal support. You meet with your adviser periodically throughout the program to review your progress and career goals, and ensure that your educational needs are being met. Your adviser may serve as a contact point for introducing you and your family to the Phoenix metropolitan area and the Mayo Clinic system.

Visiting professors

Many prominent professors visit Mayo Clinic each year. They present their work during lectures, participate in hospital rounds and have informal discussions with trainees. You are encouraged to take full advantage of these educational opportunities.

From the director

H. Vikram, program directorWelcome to the Infectious Diseases Fellowship at Mayo Clinic's campus in Arizona. We have structured a two-year fellowship tailored to specifically train the next generation of physician experts, leaders, educators, and clinical researchers in the field of infectious diseases.

Mayo Clinic training programs foster lifelong learning, create a conducive environment to deliver outstanding patient care in multidisciplinary teams, and provide unparalleled opportunities for research and education. Mayo Clinic celebrated its 150th anniversary in 2014.

Mayo Clinic School of Graduate Medical Education (MCSGME), one of the largest and oldest in the nation, reached its centennial year in 2015. The school has more than 1,700 residents and fellows at any given time and 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.

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 campus in Arizona is also one of the largest transplant centers in the southwestern United States, with programs dedicated to kidney, pancreas, liver, and heart transplantation. We also have an active blood and bone marrow transplant program housed in the new Mayo Clinic Cancer Center building in Arizona. In 2017, we welcomed our first class of medical students at the new Mayo Clinic Alix School of Medicine campus in Arizona.

The Infectious Diseases Fellowship at Mayo Clinic's campus in Arizona is one of two infectious diseases fellowship programs in the state of Arizona and the only ACGME-accredited infectious diseases fellowship in the Phoenix metropolitan area.

Our program 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. You also benefit from clinical microbiology, infection control, and travel clinic rotations at Mayo Clinic's campus in Rochester, Minnesota.

Other valuable offsite rotations include an HIV continuity clinic at McDowell 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 am confident that you will be fully equipped to pursue your chosen career path in infectious diseases.

I encourage you to learn more about our fellowship program and what we have to offer. Do not hesitate to contact me or my fellowship coordinator, Julie, if you have any additional questions.

We look forward to hearing from you soon.

HR Vikram, M.D., FACP, FIDSA
Infectious Diseases Fellowship Director


Our faculty members have extensive experience in training medical students, residents, and fellows. They have been actively involved in clinical research in diverse areas of infectious diseases, resulting in numerous seminal publications over the years. Residents, students, and fellows have vastly benefited from ongoing research collaborations, publications, and mentorship by our faculty. 

In addition to six faculty members, the division also includes an infectious diseases (ID) pharmacist, two nurse practitioners, and two nurses.

  • Antimicrobial Stewardship Program. The Arizona campus of Mayo Clinic has an active ASP that is accomplished in conjunction with ID faculty and an ID pharmacist. You have the opportunity to assist, enforce, and participate in research endeavors.
  • Mayo Clinic Outpatient Parenteral Antimicrobial Therapy (MOPAT) program. Mark W. Burns, C.N.P., D.N.P., N.P., M.S., is primarily responsible for our award-winning MOPAT Program, which has been a key component of our practice for careful monitoring and follow-up of patients on parenteral antimicrobial therapy. As a fellow, you play a key role in this process for their inpatient consultations when discharged on such antimicrobials.
