Ramanathan Yegappan researches the Development of Procoagulant-Based Rapid Wound Sealant

​Current research focusses on developing an efficacious wound dressing material based on hydrogel scaffold that brings about rapid blood clotting with the incorporation of Procoagulant Snake Venom Protein (PSVP) originally isolated from snake venom in combination with an agent to stop blood clot breakdown.

​Ramanathan Yegappan completed his Bachelor of Technology (B.Tech) in Genetic Engineering from SRM Institute of Science and Technology, India in 2015 and completed his Bachelors dissertation in Texas A&M University, US where he developed hydrogel microparticles via sequential click reactions. He was a visiting international research student in University of South Australia, Adelaide in 2015-2016 where he studied the kinetics of Diels-Alder click reactions for bioconjugation. His passion to understand material interface with biology at nano- scale motivated him to complete his Master of Technology (M.Tech) in Nanomedical Sciences from Amrita Centre for Nanosciences and Molecular Medicine, India in 2018. During his period, he was a recipient of scholarship funded by Nanomission, Department of Science and Technology, Government of India under the M.Tech program. He was also a part of various research projects related to synthesis of ceramic and polymeric nanoparticles in combination with hydrogels for bone tisse engineerning and wound healing. In 2019, he started his PhD in Australian Institute for Bioengineering and Nanotechnology at the University of Queensland under the supervision of Prof. Alan Rowan, Dr. Amanda Kijas and Dr. Jan Lauko.
