Song Li, Ph.D., integrates principles of engineering, biomaterials and mechanobiology to advance cell and tissue engineering methods. He seeks to develop stem cell-based methods to promote regeneration in the heart and neuromuscular system and to advance immunoengineering approaches to treat cancer and other diseases.

Li stands at the forefront of mechano-epigenetic engineering of cell fate, leveraging his expertise to engineer biomaterials and microdevices that effectively guide stem cell differentiation, cell reprogramming and immune cell functionalities. He has demonstrated innovation in fabricating tissue grafts and designing drug delivery platforms to facilitate the regeneration of tissues and organs such as the heart, blood vessels, spinal cord, peripheral nerves and muscles. 

Li aims to develop more efficient and precise methods to reprogram cells into induced pluripotent stem cells, and investigates the physical and chemical activities in the stem cell microenvironment that regulate differentiation processes. With this information, he hopes to mimic stem cells’ natural environments by developing physical platforms that can influence reprogramming.

Li seeks to improve immune cell memory to effectively combat infectious diseases and cancer, and is exploring novel methods to manipulate immune cells to promote tissue regeneration and develop therapeutics for diseases such as diabetes.

“Cell reprogramming is one of the most exciting advancements in biotechnology in the past 20 years. It’s the cellular equivalent of wiping your computer’s memory clean and replacing it with new software. This is a very powerful process that could lead to therapies based on patients’ own cells and their own genes.”
