    Grew up in Fort Worth, TX. Attended university there and then left the country for medical school in Grenada. I spent 2 years in Atlanta, GA for clinical rotations before matching into residency back in Texas. Pediatric Infectious Diseases and Global Health have been the long-term goals since deciding to pursue a career in medicine.

    I'm excited to be starting Infectious Diseases fellowship at both St. Jude and Le Bonheur Children's hospitals. I grew up in Seattle, WA and went to medical school at the University of Washington, but along the way I've lived in several other places, including Kansas, Chicago, Maryland and Memphis. I first moved to Memphis in 2010, and am thrilled to be staying here for Fellowship. One of my favorite things to do here is to pack a picnic, bring chairs and my partner, Josh, to the Levitt Shell on a weekend night and listen to music.

    I was born in Kingston, Jamaica and attended medical school at the University of the West Indies in Jamaica. After graduating from medical school and completing my internship, I worked as a senior house officer and then as a medical officer in the government’s health department. The experience trained me to make critical decisions in life threatening emergencies, even with limited resources available. I also witnessed a wide variety of infectious diseases that both piqued and sustained my interest in the field. My interest in HIV medicine led me to further my knowledge by participating in preceptorships and courses pertaining to the management of HIV positive patients. I came to the United States to pursue a career in Pediatric Infectious Disease and completed my pediatric residency at the Brooklyn Hospital Center in Brooklyn, New York and then trained in pediatric infectious diseases at Cleveland Clinic Children’s Hospital which allowed me to continue forward along this path. The opportunity to work at a large transplant center also enhanced my training in this field of medicine. I am a meticulous, hardworking team player with a keen interest in improving my medical knowledge and clinical skills. The opportunity to join the St. Jude’s HIV fellowship program will be a great asset to my medical prowess. Once qualified in pediatric infectious diseases and pediatric HIV medicine, I intend to contribute to medical research and to participate in global outreach with the goal of enhancing both the health care system and the education of future medical practitioners.

    My name is Kate, which is my preferred professional name, but I've also gone by Kayla during childhood and in my community. I am super excited to be a part of St. Jude and to meet all of you. I was born and raised in New Jersey but have spent the last 12 years in New York where I went to college and received my graduate and post-graduate education. I graduated from medical school at Stony Brook University on Long Island in New York where I stayed for pediatrics residency. I am thrilled to be able to do pediatric infectious disease fellowship at St. Jude. I've known I wanted to do infectious disease since my 3rd year of medical school. I also have a passion for breastfeeding medicine which has a lot more to do with infectious diseases than you might think! My husband, Max, received his graduate degree in computational biology from Stony Brook University as well and will be working at St. Jude as a post-doctoral fellow. We've been married for 9 years and have a 3-year-old daughter, named Liba, my pride and joy. I like dinner parties, reading on my couch, inspirational quotes, and having wine with friends (of course not while on service).

    I was born and raised in Memphis. I attended Emory University for undergraduate and UTHSC for medical school. I was between veterinary medicine and pediatric infectious diseases before going to medical school and now cannot wait to be a veterinarian...just kidding! I fell in love with infectious diseases from an early age as my father was an Infectious Diseases specialist at St. Jude. I loved the puzzles and complexity of cases seen throughout the field. Additionally, it was while working at St. Jude during random summers and the year before medical school that I also began to really appreciate the impact that research in the infectious diseases field can make across healthcare. Outside the hospital, I enjoy walking my dogs (and other people's dogs), kickboxing, and traveling--especially to outdoor areas where you can hike and white-water raft. I cannot wait to continue my journey in Memphis at my forever second home, St. Jude Children's Research Hospital!
