Dr. Weston’s research career began in California with studies on muscle regeneration following spinal cord injury and muscle development in sub-ideal conditions (e.g., space flight).  She then began working on bone regeneration at Loma Linda VA. Dr. Weston relocated to Florida to investigate hematopoietic stem cell characteristics and self-renewal in response to micro-environmental factors. Here, she earned her PhD in Molecular Cell and Developmental Biology. Interest in stem cell microenvironments led to studies at Miami VA on the healing effect of mesenchymal stem cell (MSC) exosome and growth factor delivery. Successes in MSC work expanded her interest in the mechanisms of allograft healing in healthy and damaged environments. She was recruited to the biotech sector by Vivex Biomedical for work at the University of Miami Tissue Bank where Dr. Weston’s innovation and leadership in product development resulted in highly effective products and multiple patents. She was offered the opportunity to continue her research at the very impressive, well-equipped Cell Therapy Institute at Nova Southeastern University. This allowed her to expand to the evaluation of microvesicles in sarcoma initiation and progression for the purpose of biomarker elucidation. While at NSU, she served the Medical School (NSU MD) on the Curriculum Committee, Pre-clerkship Committee and as the Genomics Thread Director. Her consulting activities in the biotechnology space resulted in strong and prosperous relationships with several companies where she has enjoyed the development and characterization of products for market use.
