Yifu Li, MD

Associate Research Scientist

Miguel Verbitsky, PhD

Associate Research Scientist

Shouhong Xuan, PhD

Associate Research Scientist

I study functions of genes and/or gene variants identified from human genetics studies, especially in the field of nephrology. I combine classical molecular and cellular biology, mouse genetics, stem cell biology together with CRISPR/CAS9 gene editing technology etc. during the course of investigations. I believe that in-depth studies of genes and gene variants would pave the road for more efficient and personalized diagnosis and therapy.

Hila Milo Rasouly, PhD

Postdoctoral research scientist

I am a human and mouse geneticist. I have a master in Genetic Counseling from the Hebrew University in Jerusalem, Israel and a Ph.D. in Genetics and Genomics from Boston University, MA. My career goal is to combine genomic counseling with research in the field of nephrology.

Youngji Na, PhD

Postdoctoral research scientist

My research focuses on Precision Medicine and Translational Bioinformatics by applying powerful computational approaches to solve fundamental questions in biological systems and to address clinical and health problems at the individual and population levels. My long-term research goal is connecting the molecular world to the clinical world for the benefit of human health.
