Maryland, USA
Expert's career has spanned academic research, national laboratory instrumentation development, and federal regulatory science. As a graduate researcher, Expert designed and built novel time-resolved and steady-state circular dichroism spectrometers achieving unprecedented sensitivity, and developed software for complex multidimensional spectroscopic data analysis and quantum mechanical simulations of photosynthetic protein systems. As a postdoctoral research fellow at a federal biomedical research institute, Expert developed instrumentation and control systems for time-resolved X-ray scattering, Laue crystallography, and high-pressure NMR/EPR spectroscopy, and contributed to internationally recognized research on airborne transmission of respiratory droplets relevant to COVID-19 public health guidance, for which Expert's research team received institutional recognition awards.
Expert subsequently transitioned into a regulatory science role at a federal medical device regulatory agency, where Expert designed and developed novel augmented reality and 3D-sensing test instrumentation for evaluating medical extended reality devices, and served as a regulatory subject-matter expert consultant assessing the safety and effectiveness of extended reality, endoscopic, and digital pathology AI/ML medical devices. Expert has authored numerous peer-reviewed publications and conference presentations, developed and released open-source scientific software tools, and has remained active in professional service roles including grant review for national scientific funding agencies and journal peer review across multiple academic publishers.
