In 2010, as a principal investigator, Dr. Li received a NIH grant (2010-2015) titled “Comparative Genetics of Sweet Taste in Carnivora” (R01DC010842-01A1). Now, she serves as a consultant. She also owns two patents: 

  • 2008 Li X, Li W, Reed DR, Bachmanov AA, Brand JG. A novel taste receptor of the T1R family from domestic  cat, Felis catus (US Patent No. 10/591,360, Australia Patent No. 2004256023, European Patent Appl. 04752212.3)
  • 2009 Li X, Li W, Brand JG. Taste Receptors of the T1R Family from Domestic Dog (US Patent Application No. 11/578,472). 

As an associate director of the  Cytogenetics Laboratory and an assistant professor in the UC Department of Pediatrics, Dr. Li oversees the operation of  the Cytogenetics Lab. In the last three years, she has  signed out more than 20,000 clinical cytogenetic cases with more than 35,000 tests (80% BM and solid tumors, 20% prenatal and constitutional cases). Now her focus is to develop and implement new tests and expand test menu for FISH.

From 2010-2012, she received the following board certification/license: 

  • ABMG: Clinical Cytogenetics, 09/01/2011 
  • ASCP/BOC: Technologist in Cytogenetics, 03/19/2010
  • CAP: Team member training, 11/11/2011, Team Leader training, 12/01/2011
  • New York State of Department of Health: Cytogenetics, CQ code: LIXXX5, 04/06/2012
  • National Provider Identifier (NPI) number: 1134486848

PhD: Fudan University, Shanghai, China, 1998.

Clinical Cytogenetics Training: Children’s Hospital of Philadelphia, Philadelphia, PA, 2010.
