Carola has worked in major medical centers in Brazil, some with limited resources, requiring creativity, research, and deep knowledge.Her favorite word is “homing.” When she learned about the homing of stem cells, she fell in love with the complex biochemical processes that allow stem cells (collected from a donor’s bone marrow) to be infused into a recipient’s vein and find their way home to the recipient’s bone marrow. For her, homing is closely related to belonging. These themes inspired her to write Chubby’s Tale: The True Story of a Teddy Bear Who Beat Cancer, which was listed by BookAuthority among the “Best Leukemia Books of All Time.” She also dedicated an entire chapter to the homing of stem cells in her book Pediatric Stem Cell Transplantation for Pharmacists, featured in Springer Nature’s 2020 Highlights.Her published scientific books include Pediatric Oncologic Pharmacy—A Complete Guide to Practice (2nd ed, 2026), The Golden Guide to Oncologic Pharmacy, Pediatric Hematopoietic Stem Cell Transplantation for Pharmacists—The Gold Standard to Practice, Chemotherapy and Pharmacology for Leukemia in Pregnancy—Guidelines and Strategies for Best Practices, Chemotherapy in Neonates and Infants—Pharmacological Oncology for Children Under 1 year old, and Drug Therapy and Interactions in Pediatric Oncology—A Pocket Guide.
