Howard E. Katz joins the Department as a Professor after attaining the position of Distinguished Member of Technical Staff at Bell Laboratories-Lucent Technologies. He earned a Bachelor's degree in chemistry at MIT, and conducted research on the synthesis of the antibiotic bleomycin, under Professor Sidney Hecht. His Ph.D. was obtained under Professor Donald Cram at UCLA, with a thesis based on multistep syntheses of electron-rich receptors and the relationships between receptor structure and guest cation affinity. Professor Katz then accepted a position as Member of Technical Staff at Bell Laboratories. After an initial project exploring "converse" host-guest chemistry, where anions were bound to multidentate Lewis acidic receptors, he has focused on new organic materials designed using the principles of physical organic chemistry and self-assembly, synthesized with new methods developed specifically for materials-related targets. Semiconductor devices, electro-optic switches, and information storage media with the highest figures of merit then known were produced from the synthesized materials, and the reported results have become the basis for further work in those fields both at Bell Labs and in the wider materials chemistry community. His most recent work has emphasized nontraditional device fabrication, surface chemistry, and multifunctional device design, and has led to ongoing collaborations with multiple outside companies (including one new startup) and a range of universities. His inventions have been incorporated into over thirty patents and recognized by two R&D 100 Awards. Dr. Katz has also been a mentor and collaborator to several underrepresented minority scientists among two dozen altogether, held several named lectureships at universities, and recently served as Meeting Chair and Board Member for the Materials Research Society. He is the President of MRS for the year 2004, and was recently named an AAAS Fellow. He has co-chaired DARPA-sponsored workshops in the areas of functional polymers, nanostructured materials, biomimetic circuits, and electrotextiles, as well as five other symposia. Outside of science, Howard Katz is an accomplished musician, and was the principal cellist of the South Orange Symphony Orchestra in New Jersey. He is also an avid tennis player. Professor Katz's research at JHU continues to be centered on new organic, polymeric, and hybrid materials for electronic- and photonic-based technologies. A rich variety of compounds are designed, synthesized, and incorporated into solid films and larger assemblies for utilization in a wide range of devices and components. Device of greatest interest include transistors for switching display pixels, sensors for detection of biologically and medically important vapors, memory elements for adaptive circuits and information storage, fast diode circuit elements and photodetectors, thermoelectric films, waveguides for optical communication and multiplexing, tunable antennas for control of wireless signals, capacitors for energy storage and low-power consumer electronics, and connectors for nanowire devices. By tailoring the molecular designs specifically to the desired performance targets, device responses can result that are not attainable using conventional inorganic solids, and simple, accessible processing techniques can be used. The group activities will include novel synthetic and interfacial chemistry, self-assembly and crystallization, solid state characterization, engineering of the fabrication processes, evaluation of device performance, and integration into higher-order systems. |
