Dr. Yongqiang (Yong) Feng has always been fascinated by the molecular machines driving cells’ collective behaviors in multicellular organisms. He was trained as a developmental biologist in graduate school and continued his scientific career in the lab of Dr. Alexander Rudensky at MSKCC as a postdoctoral fellow. At MSKCC, Dr. Feng contributed to work that improved our fundamental understanding of epigenetic regulation of T-cell tolerance. Dr. Feng continues his scientific explorations at St. Jude across several collaborative projects, leveraging the expertise of colleagues, and contributing his own insights to achieve groundbreaking discoveries.
