Dr. Sara Abdollahi is currently a postdoctoral fellow at Johns Hopkins University, where she worked on several projects. This includes a project developing heart patches to understand the implications of extracellular vesicles in cardiac repair. She is currently focusing on an in vitro model of Schizophrenia toward characterizing the disease using neurons from pluripotent stem cell (iPSC) and genome editing (CRISPR) technologies. Before this endeavor, Dr. Abdollahi completed her PhD at Carnegie Mellon University. Her thesis research resulted in a novel optimization strategy for soft material 3D printing and a wearable pulse oximeter with pressure sensing to assess blood oxygen saturation and activity state. Dr. Abdollahi is also interested in orthopedic technologies based on her master’s research analyzing bioactive glass surface transformations during scaffold fabrication for bone tissue engineering. This project was completed at McGill University, where she also received her bachelor’s degree in chemical engineering. Overall, Dr. Abdollahi strives to advance research at the intersection of materials, machines, and biologics while also involved in outreach, mentorship, and science communication activities.

Collection Overview

Advanced manufacturing is a collection of new or existing manufacturing processes that leverage innovative technologies. These innovations can include, for instance; automation, computation, or sensing. An example of an advanced manufacturing technique is additive manufacturing, which involves building a product layer by layer in three dimensions (3D), also referred to as 3D printing. Soft materials are increasingly used in advanced manufacturing techniques for biomedical applications because compliant materials can more easily interface with the skin. This interface is important for wearables, medical devices, surgical robots, and other applications that involve human-machine interactions. The soft materials include liquids, gels, colloids, polymers, and even biologics such as cells, extracellular matrices, and biomolecules. These biologics are used for bioprinting with a vision to systematically develop biomaterials, tissues, and even organs. The manufacturing of rigid parts also often requires soft raw materials that are subsequently transformed to establish structural integrity by crosslinking or other mechanisms. The process of making scaffolds that mimic hard tissue such as bone, for example, begins with biodegradable polymers dissolved in solvents. Taken together, the possibilities of using advanced manufacturing technology with soft materials and biologics are expanding. This collection aims to provide a snapshot of the state-of-the-art methods that combine advanced manufacturing with soft matter or biologics for biomedical applications.
