Senior Professional Research Assistant - Zamora Lab

 

Division of Pulmonary Sciences and Critical Care Medicine
and
Colorado Center for Transplantation Care, Research and Education

Transplantation microsurgery and training program

Rob Plenter has been involved in research since 1981, when he joined the Howard Florey Institute for Experimental Physiology and Medicine. It was at the HFI that he acquired a passion for surgery. He has worked in basic research and physiology labs and on human anatomy projects, at the Universities of Melbourne and Colorado and Monash University, and has publications spanning each of these disciplines. He has also presented the results of that research at many national and international conferences.

Rob joined his first transplantation/immunology laboratory at the University of Melbourne’s Department of Surgery in 1989. His specialty is microsurgery and he joined the Zamora lab at its inception in 2008. He also manages the microsurgical core and the microsurgical training program of the CCTCARE.

Rob is a member of the Academy of Surgical Research and is working toward his Surgical Research Specialist certification. He also has an active interest in the ethics of research.
