For the past twenty-seven years I have been very actively involved at Coe College in research with students. This research is on glass and is both basic and applied. In particular, our work focuses on the relationship between structure at the atomic level and resulting physical properties. We have also discovered new families of glasses by rapid cooling liquids and other means. At Coe, we fabricate glasses, perform property measurements and we do spectroscopic investigations. I enjoy the resulting interaction with people and I enjoy the discoveries we have shared. In this time I have worked with about 150 students and we have written more than 100 journal papers. Also, we have attended and given more than 100 talks at national and international scientific meetings. Our work has been supported by an interesting variety of groups including the National Science Foundation, the Research Corporation, The McElroy Foundation of Iowa, The Maytag Foundation of Iowa, The States of Iowa and Texas, The British Government, the US-UK Fulbright Commission,

Honestly, now: I like to blast glasses with lasers. To be more formal, my personal research interests lie in the area of the optical properties of glasses and the relationship between such properties and the structure of the glass. Glasses of interest to me include alkali borates, alkali bismuthates, heavy metal oxide glasses, and sol-gel glasses. In particular, my recent work has focused on bismuth-based glasses, that is, those that contain bismuth as a modifier (e.g., bismuth borates, lead-bismuth silicates), and also those containing bismuth as a non-conventional glass former (e.g., lithium bismuthates). Other recent families we have investigated include bismuth and rhenium silicates made using the sol-gel method, alkali silicates, and bismuth borosilicates. Now, why do I shoot these glasses up? Because a study of what happens can lead to a better understanding of how they are made up and where their properties come from. |

 I have been working with undergraduate students in musical acoustics research since 1990. During this period about 25 students have been involved in this research, with many of them presenting papers at national or international meetings, including meetings in Honolulu, Berlin, and Cancun. Research topics in this program have included the following: Interaction of an air jet with a Helmholtz resonator (1991-1994), Acoustics of the American reed organ (1994- ), Acoustics of the Asian free-reed mouth organs (1997-).
I have been very active in the Acoustical Society of America, serving two terms as Chair of the Technical Committee on Musical Acoustics of (1999-2005), and I am member of the Board of Advisors of the Center for the Study of Free-Reed Instruments at the Graduate School of The City University of New York. My students and I have collaborated with Thomas Rossing of Northern Illinois University, and Jonas Braasch of the Ruhr University, Bochum, Germany (now at Rensselaer Polytechnic Institute).
