Metropolitan Museum of Art

New York, NY, USA 

Julie Arslanoglu is a Research Scientist at the Met. She investigates paints, coatings, adhesives, and the organic materials found in artworks across all ages using spectroscopy (FTIR), mass-spectrometric (GC/MS, Py-GC/MS. MALDI, LCMS) and immunological techniques (ELISA), with emphasis on natural and synthetic polymer identification and degradation. Her research interests include interactions between pigments and binders, especially proteins, polysaccharides, lipids, and their mixtures.

Professor of Genomics, Physiology, and Biophysics

Weill Cornell Medicine

Director of the WorldQuant Initiative for Quantitative Prediction

New York, NY


The Mason laboratory develops and deploys new biochemical and computational methods in functional genomics to elucidate the genetic basis of human disease and physiology. We create and deploy novel techniques in genomics and algorithms for: tumor evolution, genome evolution, DNA and RNA modifications, and genome/epigenome engineering. We also work closely with NIST/FDA to build international standards for these methods (SEQC2, IMMSA, and Epigenomics QC groups), to ensure clinical-quality genome measurements and editing. We also work with NASA and other space agencies to build integrated molecular portraits of genomes, epigenomes, transcriptomes, and metagenomes for astronauts, which help establish the molecular foundations and genetic defenses for enabling long-term human spaceflight.

Dr. Mason has won the NIH’s Transformative R01 Award, the NASA Group Achievement Award, the Pershing Square Sohn Cancer Research Alliance Young Investigator award, the Hirschl-Weill-Caulier Career Scientist Award, the Vallee Scholar Award, the CDC Honor Award for Standardization of Clinical Testing, and the WorldQuant Foundation Scholar Award.  He was named as one of the “Brilliant Ten” Scientists by Popular Science, featured as a TEDMED speaker, and called “The Genius of Genetics” by 92Y. He has >230 peer-reviewed papers and scholarly works that have been featured on the covers of Nature, Science, Cell, Nature Biotechnology, Nature Microbiology, and Neuron, as well as legal briefs cited by the U.S. District Court and U.S. Supreme Court.  Coverage of his work has also appeared on the covers of the Wall Street Journal, New York Times, TIME, The LA Times, and across many media (ABC, NBC, CBS, Fox, CNN, PBS, NASA, NatGeo). He is an inventor on four patents, co-founded five biotechnology start-up companies, and serves as an advisor to 17 others, as well as 3 non-profits. He lives with his daughter and wife in Brooklyn, NY.
