Name Background  
Emily Adochio, MD Hometown: Naperville, IL
Medical School: Rush Medical College
Residency: Medical College of Wisconsin Affiliated Hospitals
Why I Chose Rush/CCH for Fellowship: I️ chose Rush because of their commitment to health equity and their work with underserved communities. Rush’s relationship with Cook County allows for fellows to work with a diverse patient population, including those that are traditionally marginalized. They also have connections with the CORE Center, and since I️ am interested in HIV, this was a big positive for me. I️ also liked the Career Development Pathway Program which allows fellows to explore many different interests in ID. Lastly, I️ went to Rush for medical school so I️ know that everyone is very nice and approachable!

Malika Gill, MD Hometown: Mesa, Arizona
Medical School: Royal College of Surgeons in Ireland School of Medicine
Residency: University of Pennsylvania
Why I Chose Rush/CCH for Fellowship: I chose Rush/CCH ID for fellowship because I wanted to train in a city where I was exposed to the diverse patient population that makes the subject of ID uniquely interesting. I felt this program would provide me with strong clinical experience I could take forward in pursuit of my interests of both global health and transplant ID. I also felt the collegiality between the ID fellows and attendings was unmatched and cultivated a supportive learning environment.

Medical School: Case Western Reserve University School of Medicine
Residency: Medical College of Wisconsin Affiliated Hospitals, Inc.
Why I Chose Rush/CCH for Fellowship: I chose Rush primarily for the sincerity and enthusiasm I noticed on my interview day, but also for the diversity of experience offered by two neighboring hospital systems. I have also long had an interest in neuroinfectious disease, something that Rush has a particular focus in.

Matt McGath, MD Hometown: Freeport, IL
Medical School: University College of Medicine in Rockford
Residency: University of Illinois College of Medicine at Peoria Internal Medicine Residency Program
Why I Chose Rush/CCH for Fellowship: I chose Rush because of the wide variety of clinical experiences afforded by working at both RUMC and Cook County. One of my main areas of interest within ID is HIV/AIDS, and the CORE Center offers an unparalleled opportunity for further education and experience in the care of patients living with HIV. Everyone during the interview day was also extremely welcoming and their passion for ID and fellow education was obvious. I am also really looking forward to living, working, and learning in Chicago, which I think is one of the best cities in the world.

Name Background  
Hillary Chang, DO

Hometown: Skokie, Illinois
Medical School: Midwestern University, Chicago College of Osteopathic Medicine
Residency: Rush University Medical Center/Cook County Hospital Internal Medicine Primary Care Program
Why I Chose Rush/CCH for Fellowship: For residency, I trained at the combined Rush/Stroger Internal Medicine - Primary Care program and I experienced how well the education at both hospitals complemented each other. Working at a tertiary care center like Rush and a safety net hospital like Stroger exposes you to a diverse patient population with various complexities and pathologies. The ID fellowship trains strong clinicians with opportunities for research, and it was an easy decision to stay for the fellowship!

Medical School: Loyola Stritch School of Medicine

I chose Rush because of the breadth of experience and exposure offered between Rush, Stroger, The Core Center, etc. as well as the vibrant faculty, and can't wait to get started at this bustling, busy academic center!

Hometown: Chandler, Arizona
Medical School: University of Miami Miller School of Medicine
Residency: Indiana University
Why I Chose Rush/CCH for Fellowship: I'm excited to train at Rush because of the breadth of clinical experiences in infectious diseases. The partnership between Rush University and Cook County Health means we get the benefits of an academic referral center and a large county hospital with an associated HIV clinic (CORE Center: one of the largest in the country).

Robert Petrak, MD

Hometown: Burr Ridge, Illinois
Medical School: St. George's University
Residency: Advocate Luthern General Hospital
Why I Chose Rush/CCH for Fellowship: I went into Infectious Disease for many reasons. I love how ID encompasses the entire body and requires you to maintain much of your IM knowledge, I find microbiology fascinating, and lastly, my family is heavily involved with infectious disease. I chose Rush because that’s where all of my ID mentors trained and it’s widely known as the best place to train for ID.
