I have a broad background in hematology, with specific training and expertise in
hematopoietic stem cell biology and the clinical aspects of platelet-related disorders.
Before establishing my research group in 2007, I served as a staff physician in the
Laboratory of Clinical Biochemistry at the IRCCS San Matteo Foundation and the
University of Pavia, Italy. In 2005-2006, I was a Visiting Professor at Dana Farber
Cancer Institute at Harvard Medical School. Since 2007, I have led a research group
with a cross-institutional presence at the Department of Molecular Medicine at the
University of Pavia and the Department of Biomedical Engineering at Tufts
University, USA. The aim of our program is to integrate biological and bioengineering
approaches to study hematopoiesis and the bone marrow microenvironment. My
research is centered on understanding how various components of the bone marrow
niche regulate platelet production. In 2011, I developed a bioengineered 3D model of
human bone marrow using porous silk, which effectively mimics the physiology of the
living bone marrow environment. This model was further refined in 2015 and 2017,
allowing us to generate functional platelets ex vivo, offering potential clinical
applications in blood component production. By 2021, we had demonstrated that this
advanced tissue system could also be utilized as a novel tool for investigating
pathological mechanisms in human platelet production and evaluating drug efficacy.
In 2024, my group generated a silk bioink as new approach to mimic the viscosity of
the native bone marrow environment. In 2025, we used a modified silk scaffold to
generate red blood cells in vitro from human hematopoietic progenitor cells.
Recently, our company, Silk4B, was incorporated with the support of the European
Innovation Council.
