Viral vectors provide one of the major platforms for gene delivery in cell and gene therapy applications. Adeno-associated viruses (AAVs) are rapidly becoming the delivery method of choice due to the possibility to generate capsids optimized to target specific tissues and cells. Development of clinically desirable AAV capsids with optimal genome design requires rapid, accurate, and robust analytical methods to confirm AAV purity, capsid titer, and DNA content.

Heidi Vitrac, Ph.D.
Tosoh Bioscience LLC
Heidi Vitrac’s academic career in France and in the US has centered around membrane biology and lipid-protein interactions. This work has been in four main productive phases: Her PhD work on the mechanisms of oxidation of biomolecules upon exposure to oxidative stress (2001-2005) was at the University of Paris Descartes. This was followed by post-doctoral research projects on the mechanisms of protein folding at the membrane interface (2006-2007) in Grenoble, France, and continued with the role of lipid-protein interactions in the structure and function of integral membrane proteins at the University of Texas Health Science Center, Houston (2008-2013). As an Assistant Professor at the University of Texas (2013-2020), her research focused on the crosstalk between membrane phospholipid metabolism, bacterial physiology, and stress adaptation. Throughout her research career, she adopted multidisciplinary analytical, biophysical, and biochemical approaches, including multiple modes of chromatography and mass spectrometry (proteomics, lipidomics, and metabolomics) to understand the mechanisms of lipid-dependent defects in the development and progression of diseases.
Heidi joined Tosoh Bioscience LLC in December 2020 as an Applications Scientist, where she is developing analytical chromatography applications on TSKgel columns for the online mass spectrometry characterization of protein biotherapeutics, from monoclonal antibodies to gene therapy delivery systems. She is also currently involved in the development of bioseparation methods combined with the Tosoh LenS3 Multi-Angle Light Scattering Detector, bringing the revolutionary approach for the measurement of molecular weight (MW) and radius of gyration (Rg) to wide-ranging applications on biopolymers, such as polysaccharides, proteins, mAbs and AAVs.
