Grad Sch: Biomedical Eng

Dr Helder Marçal is an international recognized expert in tissue engineering and regenerative medicine technologies using stem cells. His research spans multidisciplinary fields of Biomedical Engineering, Theranostics, Stem Cell therapeutics, Biosurveillance, Biomaterials, Tissue regeneration in space and Biogerontology.

 

Dr Marcal is also translating biomedical applications in autoimmune arthritis (spondyloarthritis). These inflammatory arthritis conditions associated with individuals that are positive for the HLA-B27 phenotype and susceptible for autoimmune tissue destruction. This technology leads the field for the development of a biotherapeutic to help halt the immuno-pathogenesis of these conditions. Dr. Marçal has been a finalist for inventor of the year UNSW Australia. His research has been highlighted at the Powerhouse Museum, The Sydney Morning Herald, National Geographic, Discovery Channel, ABC Catalyst, The Sunday Telegraph, NASA TVNew York Times, to name a few.

 

He has established international collaborations involving these technologies in the field of regenerative and translational medicine and presents at numerous international conferences. Dr. Marçal’s knowledge and skills span across innovative areas and he holds 7 patents in these fields. Dr. Helder Marcal specializes in tissue regeneration in Space Medicine and the impact of space travel on human physiology (mission to Mars) especially, the impact of microgravity and its effect on stem cells and tissue regeneration. Dr. Marcal introduced the area of Bioastronautics to Australia at the Powerhouse Museum in collaboration with NASA. He has been a visiting fellow at Harvard-MIT Health Sciences and Technology, McGowan Institute for Regenerative Medicine, Center for iPS Cell Research and Application and the California Institute for Regenerative Medicine (CIRM).
