Synergistic Activities

1. Served on numerous NSF review panels.

2. Developed a new interdisciplinary course, “Biological Physics.”

3. Sponsored 8 undergraduate students to date under the NSF Research Experience for Undergraduates program. Will continue with this program.

4. On-site consultant at Superconducting Technologies (1989-91). Established protocols for the advancement of science through industrial collaborations.

5. Two-year sabbatical at the National Institute of Standards and Technology, Boulder, CO. Established a mechanism for the enrichment of on-site undergraduate and graduate students at a National Laboratory.

Research activities

The Ruggiero group has long history of thin-film studies especially involving conventional tunneling and low-noise techniques including work with tunneling in superconductors, studies of barrier growth and artificial barriers, single-electron tunneling, tunneling in fullerene systems, tunneling electronics, and review articles and edited works on the subject. For example, recent work with Al-Mn in collaboration with NIST-Boulder has resulted in two recent cover articles in Applied Physics Letters (Jan. 2004 and April 2005) and a write-up of group work in Physics Today (May, 2004) and other publications.
