Nilesh Gaikwad, Ph. D., Founder and CEO

Served as a Director of Steroid Core at the NIH West Coast Metabolomics Center. His research has been focused in the areas of Metabolomics, Metabolism, Modulation of Metabolic Pathways, Mass Spectrometry and its Applications, Chemical Carcinogenesis, Food and Disease Biomarkers, and Biomarker Synthesis. Steroidomics platform that he has recently developed is the first, most advanced and unique in the world. Using this platform, we can now measure all classes (Androgens, Bile acids, DNA-adducts, Estrogens, Glucocorticoids, Mineralocorticoids, Neurosteroids, Oxysterols, Progestogens and Steroid-conjugates) of steroids with enhanced precision and sensitivity. He has patented this technology which is the foundation for the current R&D and service at the GSL. Dr. Gaikwad obtained his PhD degree from Indian Institute of Science and completed his postdoctoral training at UCSF and Harvard Medical School. Dr. Gaikwad left his tenure track professor position at UC Davis to start worlds first steroidomics company.
