Matthew D. Sonntag, Ph.D.
Associate Professor of Chemistry and Biochemistry
Science Building 341
B.A. – Coe College, 2008
Ph.D. – Northwestern University, 2013
Matthew Sonntag joined the Albright faculty in the fall of 2014 and has taught through the chemistry curriculum including general analytical chemistry, physical chemistry, advanced topics, and mathematics for chemistry and physics. His research interests involve the use of Raman spectroscopy as a tool to understand the physical and chemical properties of materials. In collaboration with undergraduates at Albright Dr. Sonntag has studied the structure and reactivity of several glassy substances. Other interests include probing the dynamics of single molecules using surface-enhanced Raman spectroscopy. He has also developed several physical chemistry laboratories.
Dr. Sonntag obtained his Ph.D. in physical chemistry at Northwestern University where he worked in the laboratories of Profs. Richard Van Duyne and Tamar Seideman. While at Northwestern he developed experimental and computational tools to study single molecules using tip-enhanced Raman spectroscopy (TERS). After graduation, Matt stayed with Prof. Van Duyne for a one year postdoctoral position developing new TERS instrumentation before accepting a position as an assistant professor of Chemistry and Biochemistry at Albright.

Areas of Research
Structure and Reactivity of Glassy Materials
Glassy materials exhibit no long range structural characteristics rather it is composed of short-range structural moieties. The structures are highly dependent on the composition of the material. Cations can be introduced into the glass in order to tune a variety of properties such as hardness, color and reactivity.
The Sonntag Lab is working to synthesize different borate and silicate glasses and probe their physical structures using Raman spectroscopy. We tune the composition of the glasses by varying the amount and identity of a metallic modifier introduced into the material. Furthermore we probe the ability of the glass to withstand exposure to a variety of acidic and basic media.
Surface-Enhanced Raman Spectroscopy
The majority of analytical techniques are ensemble measurements in that probe the response of a bulk collection of molecules where individual behavior cannot be identified. Surface-enhanced Raman spectroscopy has the ability to probe the signal of individual molecules allowing for new details regarding molecular dynamics and reactivity. This allows for a broader understanding of how the local environment influences molecular behavior.
The Sonntag lab is probing the Raman spectra of individual dye molecules to quantify how changes in their spectra may reflect changes in molecular orientation and binding. This will allow for insight into a wide variety of phenomena including chemical reactivity, diffusion, and electron transport.
