The Frozen Ones: Disputes, Divorces, And Dispositions, Sara Murray

Florida Law Review

Couples who may have been unsuccessful in their efforts to conceive naturally have found ways to parenthood through assisted reproductive technologies. In vitro fertilization is one of the most complex processes these couples pursue, and it involves creating an embryo outside of the human body and then inserting it into the woman with the hopes of successful implantation. Under the circumstances, many embryos may be created and then frozen—or cryopreserved—to prolong the availability of the process to the couple for months or even years. However, a conflict can arise if the couple gets divorced, which begs the question: what happens …

Faculty Research 2025

Methods for assessing compound identification confidence in metabolomics and related studies have been debated and actively researched for the past two decades. The earliest effort in 2007 focused primarily on mass spectrometry and nuclear magnetic resonance spectroscopy and resulted in four recommended levels of metabolite identification confidence─the Metabolite Standards Initiative (MSI) Levels. In 2014, the original MSI Levels were expanded to five levels (including two sublevels) to facilitate communication of compound identification confidence in high resolution mass spectrometry studies. Further refinement in identification levels have occurred, for example to accommodate use of ion mobility spectrometry in metabolomics workflows, and alternate …
