Rachel Lambert, MD
I was born and raised in Hattiesburg, MS. I received my BS in Biochemistry from the University of Southern Mississippi and completed medical school at the University of Mississippi Medical Center in Jackson, MS. I then spent 5 years in New Orleans where I completed my pediatrics residency with Louisiana State University Health Sciences Center and worked for 2 years in outpatient general pediatrics with Ochsner Health. I also became a certified lactation consultant during this time. However, I have always enjoyed learning about infectious diseases in pediatrics and realized that some of my favorite outpatient cases were those with complex infections. I am excited to return to fellowship here at St. Jude and Le Bonheur! Some of my research interests are respiratory viral illnesses, congenital infections, and antimicrobial stewardship. My interests outside of work are sewing, knitting, crafting, fashion, and rose gardening.

Hayley Scheerer, MD
I was born and raised in Kansas City, MO. Completed undergraduate at Truman State University and returned to Kansas City for three years to study olfactory neuroscience at the Stower’s Institute for Medical Research. I attended medical school at the University of Missouri-Columbia School of Medicine and moved to Memphis to complete my pediatrics residency at University of Tennessee Health Science Center, with plans to eventually complete a fellowship in Pediatric Hematology/Oncology. However, during my residency, I fell in love with the complexity and challenges presented in infectious diseases in the immunocompromised host. Due to the diverse and numerous opportunities provided at St. Jude and Le Bonheur Children’s, I am very excited to continue my medical training in Memphis! My academic interests include infections in the immunocompromised host and antimicrobial stewardship. When I’m not at the hospital, I enjoy cooking, hanging out with my pet chinchilla, exploring Memphis’ numerous restaurants and breweries, and cheering on my beloved Kansas City Chiefs!
