Recent News

I recently joined the faculty at Ohio University, and I am in the process of setting up my research lab. Please feel free to contact me if you wish to know more about my research interests or if you wish to speak about potential collaboration opportunities.

Education

Dissertation: Rod-like Plasmonic Nanoparticles as Optical Building Blocks: How Differences in Particle Shape and Structural Geometry Influence Optical Signal

Research

  • Forensic Analytical Chemistry
  • Microscopy-based Imaging and Spectroscopy
  • Plasmonics
  • Catalysis

Classical analytical chemistry revolves around the use of wet chemistry and instrumental techniques to separate, quantify, and identify the chemicals present in a bulk sample. The recent trend has been to detect and study materials as single particles/molecules on the nanoscale (1 – 100 nm). At that size, some elements such as gold and silver exhibit intense optical properties at visible wavelengths due to a phenomenon known as localized surface plasmon resonance. Plasmonic nanoparticles can in turn be used as sensors for detecting analytes at extremely low concentrations. From an instrumental methods point of view, analytical chemists prefer to study each single particle with multiple non-destructive techniques, in order to make an accurate characterization. As a result, technology in the field of microscopy has undergone many advances in the past decade.

I oversee the Avstin Microscopy Lab. Pronounced “Austin”, Avstin stands for “Analyze, Verify, Spectroscopy + Imaging, down to the Nano.” Research in my lab utilizes a variety of tools and techniques from single particle research and applies them to problems of interest to forensic science, environmental science, and catalysis. Individual projects range from ion detection to single particle characterization to instrument development. Furthermore, because communication of ideas is especially crucial to forensic science, I am interested in using new and effective ways of communicating my group’s work to the general public.

Students interested in knowing more about my work are encouraged to contact me by email.
