**About the Special Issue Editors**

**Murat Guvendiren** is Assistant Professor at the New Jersey Institute of Technology (NJIT). He earned his B.S. and M.S. degrees in Metallurgical and Materials Engineering from the Middle East Technical University in Ankara (in Turkey). He was awarded his Ph.D. from Materials Science and Engineering at Northwestern University, which focused on adhesion in hydrogels and glassy polymers. His postdoctoral training was conducted at the University of Pennsylvania, focusing on stem cell interactions with dynamic and patterned materials. He was Research Assistant Professor at the New Jersey Center for Biomaterials at Rutgers University between 2013 and 2016. He joined NJIT in 2016, with a primary appointment in the Chemical and Materials Engineering Department and a joint appointment in the Biomedical Engineering Department. His research group focuses on the development of novel biomaterials (and bioinks) with user-defined and dynamic properties, investigation of cell–biomaterial interactions, and additive manufacturing (including bioprinting) of tissue engineering constructs and in vitro disease models.

**Vahid Serpooshan** received his BS.c. and MS.c. in Materials Science and Engineering at Sharif University (Iran, 2003) and Ph.D. in tissue engineering at McGill University (Canada, 2011). His Ph.D. research focused on the design of scaffolding biomaterials for bone tissue engineering applications. Following his Ph.D., he worked for 7 years at Stanford University School of Medicine as Postdoctoral Fellow (Pediatric Cardiology) and Instructor (Stanford Cardiovascular Institute). At Stanford, Dr. Serpooshan's research mainly focused on developing a new generation of cardiac patch device to repair heart tissue following heart attacks. The patch was successfully tested in animal models and is now in clinical trials. He also worked on enabling technologies for human–machine hybrid cardiac tissue using 3D bioprinting. In 2018, Dr. Serpooshan joined Emory University and Georgia Tech as Assistant Professor of Biomedical Engineering and Pediatrics, where his multidisciplinary team is now working on a variety of 3D bioprinting-based tissue engineering projects.
