Anh Do, PhD

Research Statistician II

Dr. Do works as a Research Statistician in the Cruchaga Lab from early 2022.  She was trained as a genetic epidemiologist at the University of Alabama in Birmingham to work on different genomic data including GWAS consortia, exome chip, exome sequence in multi ancestries and family-based studies using various statistical methods.  She actively worked in pharmacogenomics and epigenetics projects in the CHARGE consortium as well as identified risk locus associated cardiovascular-related outcomes. During her postdoctoral training at Icahn School of Medicine at Mount Sinai in New York City, she expanded the genomics skillsets by emphasizing on integrating multi-omic data. She led and collaborated in the development of pipelines for the analysis of large-scale epigenome-, transcriptome-wide, microbiome, and metabolome datasets.  She contributed to projects on identifying novel genes associated with reaction severity among peanut allergic children by integrating transcriptome-wide and epigenome datasets, as well as assessing key drivers of asthma using probabilistic causal networks.

Naeimeh (Mojgan) Tayebi, MD, PhD

Senior Scientist

Dr. Tayebi is a physician-scientist who has had extensive training and experience on four different continents and countries including Iran, Singapore, Germany, Canada, and now the United States. After graduating from medical school in Iran, she went on to serve professionally in the human genetics field because of her enthusiasm for hereditary disorders. Thereafter she decided to continue her studies in the human genetics field in Singapore, and most of her research centered on GWAS. She applied for a PhD position at Max Planck Institute for molecular genetics in Berlin, and joined the research group of Prof. Stefan Mundlos. As a PhD candidate, she was able to find the pathogenic variants in a novel gene called ZAK in WES data. After that, a mouse model using CRISPR/Cas9 was generated to address the possible correlation between limb phenotype and Zak gene. Her first postdoctoral training at Hospital for Sick Children in Toronto was focused on hypertrophic cardiomyopathy along with hiPSC-cardiomyocyte disease modeling using CRISPR/Cas9. During her second postdoctoral position at Washington University with Dr. Gurnett’s group in St. Louis, she did a lot of research along with publications in Glut1DS. She joined Dr. Cruchaga lab in May 2023, and works with hiPSC derived neurons from patients with AD, controls and is involved in analyzing RNA sequencing data.
