Fulbright Scholar from Ukraine joins the group this year in October

Dr. Ihor Tarnavchyk from Organic Chemistry Department at Lviv Polytechnic National University, Lviv, Ukraine received a Fulbright Scholar Award to visit and carry research project at Coatings and Polymeric Materials Department. He will be working in our group for 9 months beginning October,2011. The project title is Novel Biodegradable Nano and Microhydrogel Systems for Cancer Drug Delivery. The goal of his project is to design, synthesize and study the new biodegradable nano- and microhydrogels (hydrogel particles) with hemocompatible properties for cancer drug delivery systems.These polymeric biomaterials are foreseen to allow forming self-organized nano- and microsized carriers for drug delivery. Polypropylene glycol hydrophobic shells of the hydrogel particles will be able to solubilize drugs, whereas external polyethylene glycol layer will provide hemocompatibility of such systems. Subsequent hydrogel particles biodegradation is foreseen due to “pseudo” polyaminoacidic core nature.

Ihor received his Bachelor of Engineering in 2004, Master of Science in 2005, and PhD degree in 2009 at Lviv Polytechnic National University in Ukraine.

In April and May of year 2008, Ihor Tarnavchyk (being a graduate student at that time) has visited NDSU and worked as a short-term visiting scholar in our group. Ihor has conducted research on the development of reactive hydrogel networks for the fabrication of metal-polymer nanocomposites.
