Spring 2025 BioE Seminar: Dr. Tatiana Segura
Speaker: Dr. Tatiana Segura, Professor of Biomedical Engineering, Duke University
Day and Date: Friday, May 2, 2025
Time: 10:45 - 11:45 AM
Location: HST 101
Abstract:
Microporous annealed particle (MAP) scaffolds are materials composed of hydrogel microparticle (HMP) building blocks. Thus, rather than use polymers as the building block that form the hydrogel, we use particles. This makes MAP scaffolds granular materials, which open unique properties such as inner porosity, exterior porosity, injectability, and heterogeneity. We have found that these properties make MAP uniquely suited for applications in tissue regeneration applications. We have found that simple changes in the MAP composition can have dramatic changes in the immune response to the material and subsequent regenerative healing response. This talk will cover the concept of MAP, software that we have developed to understand MAP microstructure, and some of our findings that relate the immune response and regenerative healing.
Personal Bio:
Tatiana Segura received her B.S. from the University of California, Berkeley (UC Berkeley), her doctorate from Northwestern University, and her postdoctorate at the Swiss Federal Institute of Technology. She began her independent career at the University of California, Los Angeles (UCLA) reaching the title of Professor of Chemical Engineering. At UCLA she participated actively in service culminating with her election as department Vice Chair and running the Graduate Program. At Duke she has continued to be heavily involved in service at the department, school, and university level. She is currently Co-director of the Center for Biotechnology and Tissue Engineering and serves as MPI of a T32 Biotechnology Training grant. Professor Segura has received numerous awards and distinctions during her career, including being named a Senior Member of the National Academy of Inventors, receiving the Acta Biomaterialia Silver Medal, a CAREER Award from the National Science Foundation, and an Outstanding Young Investigator Award from the American Society of Gene and Cell Therapy. She was also named a Fellow of the American Institute for Medical and Biological Engineers (AIMBE). Professor Segura has published over 100 peer-reviewed papers and reviews and has over 10,000 citations.
