Maria Lemma, Senior Research Technician

Maria Lemma is a Senior Research Technician at CAG. She joined us in July 2007 and leads Pre-PCR processes in the Illumina genotyping lab. She also has experience with DNA extraction, DNA quantitation using various methods, bisulfite conversion of DNA for methylation studies, and sample banking and management.

She holds a BA in Biology with specializations in Molecular Biology and Genetics from the Honors College at Rutgers University. Before working at CAG, she had an internship at the Coriell Institute for Medical Research as part of the National Institute of Neurological Disorders and Stroke (NINDS) program.
