For any biomedical (or medical) students understanding the roles of genes, genome analysis, epigenetic regulation, cell to cell signaling, and the cellular and the molecular pathways that play crucial roles in homeostasis are crucial. Considering the complexity of these subjects, I strive on transferring my knowledge to other students. I have gained a significant understanding of this subject by following the relevant course and performing three internship project in this field. I will aim for students to get understanding of the structure and function of macromolecules, cell-to-cell interactions, signaling pathways, and cellular homeostasis. Finally, I will give a possibility to students to discuss abruption in any of these processes that contributes to devastating diseases.
