Geoff Wahl

Professor
Daniel and Martina Lewis Chair

In 1970, Dr. Wahl was awarded his B.A. in Bacteriology from the University of California, Los Angeles. In 1976, he received a Ph.D. in Biological Chemistry from Harvard University. He was a Research Assistant at the University of Utah from 1975 to 1976 and a Postdoctoral Fellow at Stanford University from 1976 to 1979. He then joined the Salk Institute as an Assistant Professor in the Molecular Biology and Virology Laboratory. Dr. Wahl received his present appointment as Professor in the Gene Expression Laboratory in 1989. Dr. Wahl is an Adjunct Professor in the Biology Department at the University of California, San Diego.

Staff Scientists
leo-li

Yao-Cheng (Leo) Li

Staff Scientist

Yao-Cheng (Leo) Li, Ph.D. graduated with a B. S. in Plant Pathology, 1992 from National Chung-Hsing University and a M.S. in Biochemistry, 1994 from the National Yang-Ming University, Taiwan. He graduated in 2002 with a Ph.D. in Pharmaclogy from the State University of New Jersey and Robert Wood Johnson Medical School, New Jersey. Leo joined the Wahl Lab in 2003.
Postdoctoral Fellow
nikki

Nikki Lytle

Postdoctoral Fellow

Nikki Lytle, Ph.D. graduated with a B.A. in Biology and Religious Studies in 2010 from Willamette University in Oregon. She went on to work as a Research Assistant studying adenosine signaling in neurological diseases at Legacy Research Institute. In 2018, she received her Ph.D. in Biomedical Sciences from the University of California San Diego, where she studied signals that maintain aggressive, therapy resistant pancreatic cancer cells. Nikki’s research is now focused on understanding how perturbations to tissue homeostasis, such as obesity and fibrosis, can alter disease progression in both pancreatic and triple negative breast cancer.
Queralt Vallmajo

Queralt Vallmajó Martín

Postdoctoral Fellow

Queralt Vallmajó Martín, Ph.D. graduated with a Bachelor in Biotechnology in 2011 from Universitat Autònoma de Barcelona in Catalonia, Spain. She then pursued her Master in Biomedical Engineering at ETH Zürich, Switzerland, and went abroad for her Master Thesis, completed at the Harvard-MIT Division of Health Sciences and Technology where she worked on novel elastic biomaterials. In 2019, she received her Ph.D. in Biotechnology and Bioengineering from EPF Lausanne, Switzerland, where she established bioengineered human bone marrow models utilizing synthetic and chemically defined biomaterials to investigate cancer osteotropism in vivo. Queralt’s research is now focused on elucidating the role of the stromal population in the onset and propagation of pancreatic cancer. To do so she will employ cutting-edge bioengineering approaches offering a unique opportunity to study the interaction between stroma and epithelial cell populations, and the role of cell-matrix interaction/deposition, both in vitro and in vivo.
Zhibo Ma

Zhibo Ma

Postdoctoral Fellow

Zhibo Ma, Ph.D. graduated with a B.S. in Molecular Biology and Biochemistry in 2010 from China Agricultural University. In 2018, he received his Ph.D. in Cellular Biology from University of Georgia, studying chromatin insulators and gene regulation in fruit fly. Zhibo expanded his skills kit from ”wet” benchwork to bioinformatics towards the end of his Ph.D. training and joined the Wahl lab in December 2018. He is now interested in understanding the heterogeneity and cell state changes during normal mammary gland development and in triple negative breast cancer by using various single cell technologies.
