Regenerative biomaterials
Material systems for guided bone regeneration and tissue integration under variable healing conditions.

Eylül Yakar
PhD student in Nanotechnology and Nanomedicine at Hacettepe University.
I work on biomaterials, surface engineering, and regenerative medicine — mainly how material surface chemistry and micro/nanoscale topography affect cell behavior and tissue integration.
Research focus
Biomaterials and cell–material interactions
My background is in biomedical engineering, electrochemical nanostructure synthesis, and antibacterial, implant-related biomaterials. I am now extending this toward soft-tissue–material interactions and regenerative interfaces.
Surface & nanoengineering
Electrochemical nanostructuring of titanium-based surfaces and the effect of micro/nanoscale topography on material performance.
Cell–material interactions
How surface properties affect cell organization, cytocompatibility, antibacterial behavior, and host response at biomaterial interfaces.
Selected work
Projects
Completed experimental work alongside an exploratory model I am developing for my PhD research.
Mechanical context and directional cues at an exposed GBR interface
Qualitative, rule-based models examining two related but biologically distinct questions in the context of early GBR membrane exposure: whether gingival fibroblast responses to microgrooves depend on ECM mechanical state, and how wound geometry and competing directional cues may influence collective epithelial re-closure. The models are hypothesis-building tools, not biologically calibrated predictions.
