BIOGRAPHICAL SKETCH

Cindy Qi, Ph.D., an assistant professor of medicinal chemistry, received her B.S. in Polymer Chemistry from Peking University, and an M.S. in Organic Chemistry from Wayne State University. After completing her Ph.D. training in bioorganic chemistry with Dr. Richard Roberts at Caltech, Dr. Qi pursued postdoctoral studies of apoptosis in cancer research at UT Southwestern Medical Center under the mentorship of Dr. Xiaodong Wang. She then gained extensive expertise in peptoid library screening at Scripps Florida working with Dr. Thomas Kodadek as senior scientist. She has conducted research in the areas of organic synthesis, biochemistry, chemical biology and cancer biology. These opportunities have allowed her to address interesting and novel questions through a variety of biochemical approaches, collectively leading to coherent answers to these problems. These projects will provide a better understanding of the underlying mechanisms of certain diseases, along with elucidating regulatory functions of novel small molecules obtained from large peptoid library screening. Together, these studies will lead to novel and highly specific methods for the prevention, diagnosis and treatment of human diseases.

RESEARCH INTERESTS

Conduct research at the interface between Chemistry and Biology with focus on Medicinal Chemistry. Develop innovative technologies in peptoid synthesis and application, peptide and protein engineering, and microarray high through-put screening. Address biologically significant problems in chemical biology and cancer biology, including signaling pathways, cancer pathogenesis and significant functional roles of regulatory molecules in those biological processes.

Current Areas of Research:

  • Develop new methods to synthesize cyclic and conformation constrained peptoids.
  • Probe complex signaling pathways such as apoptosis with regulatory molecules from large peptoid library screening and elucidate their roles in cancer biology.
  • Develop facile peptoid and microarray screening to rapid identify high affinity GPCR ligands from large combinatorial library using multi-color quantum dots labeled cell-based screening and microarray technology.
