Peter Llontop

QC Analyst

Peter received his Bachelor of Art degree in Biological Sciences with an emphasis in Immunology from San Jose State University in 2016. While at SJSU, Peter was a member of Dr. Tzvia Abramson's Immunology Lab experimenting with Mesenchymal Stem Cells as a potential vehicle for antigen presentation against Bordetella pertussis, the causative agent of Whooping Cough. Prior to his transition to the Stanford LCGM, Peter worked as an Immuno-Oncology R&D Research Assistant at BD Biosciences, in San Jose, CA, where he became proficient in flow cytometry, along with cell culturing of various cancer stem cell lines. He then acquired cGMP experience while working as a Manufacturing Associate at Asterias Biotherapeutics, Inc., in Fremont, CA, where he participated in the cell banking of Human Embryoic Stem Cells for their ongoing Phase I/IIA clinical trials. Recently, Peter joined the Stanford LCGM as a Manufacturing Specialist but has since transitioned in his current role as a Quality Control Associate. He hopes to continue supporting LCGM projects in his new role.

Fariba Fazeli, MD

Senior QC Analytical Scientist

Fariba received her M.D. degree from Marche Polytechnic University, Italy. She has more than 20 years of academic and industry experience in  immunology, oncology, microbiology, and molecular genetics. Prior to joining LCGM, Fariba was the senior development scientist at IncellDx, where she supported validation of cell based assays such as Fluorescent In Situ Hybridization and Multicolor Flow Cytometry for diagnosis  of  cervical, lung, breast, bladder cancer and various life-threatening infectious diseases. Her projects were from the earliest phases of research through process development and optimization of assays for IVD/CE-IVD prodcuts.

At LCGM, Fariba is responsible for supportting various QC assay qualifications and validations for clinical production of products at different phases according to ICH and FDA guidelines.

Azadeh Timnak, PhD

QC Analytical Scientist

Azadeh received her Ph.D. in Bioengineering from Temple University, Philadelphia in 2017 where she developed a novel immunomodulatory wound healing patch and investigated polarization behavior of macrophages in skin wound healing. Over her postdoctoral training at University of Pennsylvania, department of Orthopedic Surgery she studied distribution profile of immune cells in tissues in which, due to a rare genetic disorder known as Fibrodysplasia Ossificans Progressiva, ectopic bone formation had occurred. Prior to joining LCGM, Azadeh was a scientist at Liquid Biotech USA where she optimized a detection method for circulating tumor cells using a telomerase-specific adenovirus. When at Liquid Biotech she wore multiple hats of design of experiments, assay development and data analysis for downstream immunophenotyping of infected cells.
