About Us

Cecilia Persson - Professor

I lead the BioMaterial Systems (BMS) research group within the Division of Applied Materials Science. My aim is to take an integrated approach to solving clinical problems. To do this, we use our combined competence in materials science, mechanical and biological engineering. Projects revolve around the development and characterization of new biomaterials but also characterization of soft and hard tissues. Other projects focus on the design and characterization of implants, alone or in combination with tissues.

Gry Hulsart Billström - postdoctoral researcher

I am a post-doctoral researcher in the BMS group. My main interest is to explore the biological response of biomaterials tailored for bone. I do that by in vitro and in vivo models, which I try to optimise to mimic clinical situations and addressing the 3Rs from Russell and Burch. We work with patient tissue, cell culture and especially in vivo longitudinal imaging using µCT and radio-nuclear imaging. My aim is to visualize the biomaterial's action in vitro and in vivo.

Charlotte Skjöldebrand - PhD Student

My research concerns characterization of silicon nitride based amorphous coatings for joint implants. Coating are investigated because of their possibility to reduce the wear and ion release and consequently increase the lifespan of joint implants. I evaluate these coatings using nanoindentation, XPS, SEM, AFM, XRD as well as cell studies. Read more about my research here.

Hanna Nilsson Åhman - Industrial PhD Student

I am a PhD student working on joint project between Uppsala University and the research institute Swerim, Stockholm, where we will be looking at developing magnesium-based alloys for additive manufacturing. Magnesium alloys have an excellent biocompatibility, suitable mechanical properties, and biodegradability, making it a promising material for orthopedic scaffolding applications. Combined with additive manufacturing it allows for the manufacturing of patient-specific implants.

Jenny Carlsson - PhD Student

I am a doctoral student in solid mechanics. I work on numerical modelling of rapid fractures in cellular materials, with special focus on wood and bone. I am especially interested in phase field models for fracture, which I find mathematically beautiful since they give the crack path as a result of free energy minimisation.

Elin Åkerlund - MSc Student

I am a chemical engineering student and I will be doing my master thesis in the BMS group from January to June 2019. My project consists of preparing optimal blends with different compositions of two biodegradable polymers, namely PLA and PCL, to allow extrusion of filaments for FDM-based 3D printing. I will also prepare polymer composite filaments by adding minerals, mainly calcium phosphates, to the blends. The combination of the both polymers can provide a polymeric matrix more suitable for bone applications, especially when minerals are incorporated into these polymeric matrices. The polymer matrices will be characterized by DSC, TGA, FTIR, XRD and SEM.

Yuling Liu - MSc Student

I am a master student in chemistry doing my master thesis in the BMS group from January to June 2019. My degree project will focus on optimizing the foaming conditions of porous bioceramics based on spider silk protein-ladden calcium phosphates. The project aims at combining calcium phosphates, apatite and brushite with recombinant spider silk as a foaming template. The materials will be later used in vitro to assess the synergy of the organic and inorganic matrices as a potential scaffold for bone regeneration.
