Dr. Luiz E. Bertassoni graduated with a DDS degree from Pontifical Catholic University of Parana (PUCPR) in Brazil, obtained a PhD in Biomaterials and Bioengineering from University of Sydney, and two postdoctoral degrees from University of California San Francisco, and the Harvard-MIT Division of Health Sciences and Technology. Currently, Dr. Bertassoni is an Assistant Professor at Oregon Health and Science University-School of Dentistry. He also holds appointments at the OHSU Center for Regenerative Medicine and Department of Biomedical Engineering at OHSU School of Medicine. Luiz is also a honorary lecturer in Biomaterials and Bioengineering at University of Sydney-School of Dentistry. Dr. Bertassoni leads a multidisciplinary research group working on various aspects of biomaterials and tissue engineering. His   recent  work  on  bioprinting  for vascularization of tissue engineering constructs has received extensive attention in the popular media, including Fox News, BBC, The Guardian, Fox Business,, Tech Crunch, etc; and was recently selected as one of the top 100 science stories of 2014 (#64) by Discover Magazine. Luiz is a recipient of over 20 national and international research awards, 9 competitive research grants and has received over $3 Million in research funding. Luiz currently serves as an ad-hoc reviewer or editorial board member for over 30 journals. Dr. Bertassoni's research studies the use micro-scale technologies and bioprinting for tissue engineering; nanoscale structural and mechanical properties of mineralized tissues; and different aspects of the emerging field of ‘organs-on-a-chip’.
