Research Associate
Chemistry

Overview


I'm a postdoctoral associate in the department of Chemistry at Duke University. My primary interests are light-matter interactions at the nano- and micro-scale. My main research focus at the moment is improving diagnosis of cutaneous melanoma with advanced microscopic methods (pump-probe microscopy). More broadly, I am also interested in optical levitation and it's application to fundamental physics, i.e. macroscopic quantum physics, as well as sensing.

Noninvasive identification of carbon-based black pigments with pump-probe microscopy.

Journal Article Science advances · December 2024 Carbon-based black pigments, a widely used class of pigments, are difficult to differentiate with the noninvasive techniques currently used in cultural heritage science. We use pump-probe microscopy, coupled with a support vector machine, to distinguish co ... Full text Open Access Cite

Non-destructive three-dimensional imaging of artificially degraded CdS paints by pump-probe microscopy

Journal Article JPhys Photonics · April 1, 2024 Cadmium sulfide (CdS) pigments have degraded in several well-known artworks, but the influence of pigment properties and environmental conditions on the degradation process have yet to be fully understood. Traditional non-destructive analysis techniques pr ... Full text Open Access Cite
