Walter Smith

Walter Smith is The Paul and Sally Bolgiano Professor of Physics and Professor of Physics and Astronomy at Haverford College, where he conducts cutting-edge research in nanoscale and molecular electronics. His work bridges physics, chemistry, and biology, focusing on the photoelectronic properties of self-assembled porphyrin-based nanostructures.

His research explores two main directions: (1) peptide-porphyrin hybrid systems that self-assemble into nanofibers, offering potential for biosensors and photon-based computing; and (2) entirely porphyrin-based self-assembled nanorods, nanotubes, and nanotapes that exhibit unique photoelectronic behaviors such as memory effects and trainable zero-bias photocurrents. These phenomena are being studied to understand conduction mechanisms and explore applications in solar energy and molecular electronics.

Walter Smith's scientific contributions are recognized through his endowed professorship. His collaborative work involves researchers from the Chemistry and Biology departments at Haverford, the University of Pennsylvania, and Sandia National Labs. Students in his lab gain expertise in atomic force microscopy, optical techniques, and low-noise electrical measurements, often engaging in interdisciplinary projects with real-world applications.

He mentors students in hands-on research, supervising projects that involve characterization of electrical and optical responses in nanostructures. Though specific grant details are not listed, his research infrastructure and external collaborations suggest active funding support. His lab emphasizes experimental skill development and scientific inquiry at the intersection of physics and nanotechnology.

Walter Smith leads a dynamic research group focused on advancing functional nanomaterials. His team works primarily at Haverford, with occasional visits to the University of Pennsylvania for electron microscopy and collaborative meetings. The lab fosters a multidisciplinary environment where physics students engage with biological and chemical systems, promoting innovation in nanoelectronics and energy conversion technologies.
