Area of Science:

• Stem cell biology
• Neuroscience
• Drug discovery

Background:

• Induced pluripotent stem cells (iPSCs) are valuable for modeling human diseases, especially when primary cells like neurons are inaccessible.
• Advancements in iPSC technology enable large-scale phenotyping and high-content screening of compounds in specialized cell types.
