Brief description of on-going research

My research of interest focuses on the molecular side of cell interaction. Interaction can be created by exposure of cells to various molecules or through site directed mutagenesis that result in knocking out of genes. My interest covers both prokaryotic cells and eukaryotic through either bacterial or stem cell interaction.

Currently, I am focusing my effort to understand the process of bone regeneration. By exposing stem cells to various molecules, we can analyze the effect on the cells through either visual, chemical or gene expression analysis. With little being understood in terms of understanding bone regeneration, we are focusing our effort on understanding how the various molecules within the cell interact with each other during the bone regeneration processes. This will lead to better understanding of the healing process and therefore be able to find innovative means to speed up or enhance the bone regeneration process especially in case of large bone losses.

Once we are able to advance in this task, the next step is to work towards clinical applications of our acquired knowledge and to practically apply what we have observed. Together with creating better scaffolds and molecular interaction of drugs, we are working to improve the lives of people affected by large bone loss condition or situations.
