Biography
Over the course of my a career I have developed new ways to make accurate and precise measurements of analytes in challenging environments. To drive innovative research forward a meaningful measurement must be accurate and placed in context. New approaches require a combination of methods spanning different disciplines, thus placing my work at the interface between disciplines including chemistry, materials science, separation science, nanotechnology, microfluidics, device manufacturing, environmental sciences and life sciences. This multidisciplinary intersection is especially true at my current position with the University of Arizona Center for Integrative Medicine where I seek to understand, from a systems biology perspective, the dynamic two-way interaction of humans with their environment through novel measurements of small molecules, peptides and protein biomarkers in sweat. The knowledge gained is used to guide development of non-invasive and continuous assessment of human health, well-being and performance. Additionally I have previous experience with small business entrepreneurship and partnering with companies in the biotech, manufacturing, environmental and pharmaceutical arenas.

Chemrxiv, 1-21. doi:10.26434/chemrxiv.12931769More infoHuman eccrine sweat contains numerous biomarkers which can provide information on health, performance, and aging. Non-invasive collection and measurement of biomarkers has become especially important in recent times given viral outbreaks like SARS-CoV-2. In the current study we describe a method of sweat collection from palmar surfaces in participants via surface capture using glass beads and the resulting analysis of biomarkers from very low volumes of sweat using liquid chromatography mass spectrometry with selected ion monitoring. Study participants underwent a cognitive and physical stress task with easy and hard conditions with sweat being collected after each task. Resulting analysis found a signal for 22 steroid biomarkers and we report detailed information on selected biomarkers, given their applicability to timely real-world exemplars, including cortisol, dehydroepiandrosterone, allopregnanolone, estrone, aldosterone, and 20α/β-dihydrocortisone.
