Yana Ryan

Staff Scientist

Yana Ryan, M.S.

Yana received her BS (Oakland University) and MS (Bowling Green State University) in Molecular Biology. For her graduate thesis, she studied metabolic regulation of photosynthetic bacterium stains using Transmission Electron Microscopy (TEM) by assessing their cytoplasmic membrane differentiation. She then applied her TEM expertise in ultramicroscopic diagnostics in CAP-certified Clinical Pathology Electron Microscopy Facility at the University of Toledo Medical Center. Next, she continued her work in a pre-clinical lab at the Center for Rare and Neglected Diseases (University of Notre Dame) testing therapeutics against recombinant malarial proteins and tracking plasmodium parasite invasion at the blood stage, as well as applying novel therapeutics in a murine model of a rare childhood lysosomal storage disorder, NPC. She later joined the Newborn Screening Program, a CLIA-certified public health lab for the State of North Carolina, screening newborns for inborn errors of metabolism and other disorders where she developed expertise in ARMS-PCR (screening galactosemia), Real Time-qPCR (screening SCID) and Next Generation Sequencing (screening Cystic Fibrosis). 

As a staff scientist at GSSC, Yana assists researchers with both NGS library preparations as well as Next Generation Sequencing.

Hassan Chaib, Ph.D.

Director of Laboratory Operations,

Hassan has a Ph.D. in Human Genetics. He used early cutting edge technologies of the human genome to identify the first genes causing hereditary hearing loss. During postdoctoral and junior faculty positions at the University Michigan, he pioneered microarray technologies in the prostate cancer field and the identification of genes involved in kidney disease. In 2011, he joined the Genetics Department at Stanford University, focusing on next generation sequencing technologies and stem cell therapy of muscular dystrophy. He led several projects between Stanford and the major sequencing companies Illumina and Complete Genomics. He is currently the Director of Lab Operations for SCGPM and the GSSC and Director of Stem Cell Genomics at the CIRM CESCG. Hassan is a co-author of 30 manuscripts.



Selene Banuelos

Staff Scientist

Selene Banuelos

As a Life Science Research Professional at SCGPM, Selene supports the Genome Sequencing Service Center (GSSC) on the library side doing essential work in library preparation. Her primary duties are on the MoTrPAC project where she is respinsible for DNA/RNA extration, RNA library preparation, and exome library creation. Prior to joining the team, Yana was an intern at Genetech. She recieved her Bachelor's Degree in Mollecular, Cellular, & Developmental Biology from the University of California, Santa Cruz where she worked in Doug Kellog's lab.

Peter Maguire

Bioinformatics Data Scientist

Peter Maguire

Peter Maguire is currently the Bioinformatics Data Scientist for the Genome Sequencing Service Center (GSSC) and Dibates Genomics Analysis Core (DGAC) at Stanford's School of Medicine. His focus is on using his extensive experience in sequencing to build and improve analysis pipelines, develop novel software packages, and support the Stanford community through the foundation of a highly attended bi-weekly drop-in consulting session/service. During this time, his main research focuses have been in the analysis and interpretation of RNA-Seq and WGS data for the characterization of the effects of various therapeutics on cardiomyopathy patient cell assays or for the identification of novel biomarkers of diabetic patients.



Samira Karimi

As a Staff Scientist at the Genome Sequencing Service Center (GSSC), Samira's primary duties are to assist clients in quality control, library preparation, and sequencing.  Samira graduated with a BS in neuroscience at the University of California, Santa Cruz, with a focus in bioinformatic and programming techniques.  Her main interests lie within the field of pharmacogenetics and Next-Gen Sequencing.
