Simona is a 3rd year MD-PhD student at HMS. In the lab, she is currently investigating blood stem cells during early development and is part of the Developmental and Regenerative Biology Program (DRB) at Harvard. Outside of the lab, she is passionate about improving communication and collaboration between different groups to improve solutions to both local and global (health) issues. Last summer, she was fortunate to discuss disease prevention, health promotion, and vulnerability reduction at the Faculdade de Medicina da Universidade de São Paulo (FMUSP) with fellow medical students from different parts of the world and public health experts from Brazil. Perhaps the two greatest group realizations during the course were that 1) each health care system has a great deal to learn from and offer to different systems throughout the world and that 2) instead of top-down policies to address public health issues, we should adopt more community-engaging approaches to identify the most burdensome problems that communities face and to address them in ways that will actually be effective. She hopes that increasing collaboration at both local and large institutional levels will lead to greater efficiency in solving healthcare problems and distribution of resources, particularly in biomedical research.
