I serve on the long-range planning, computer and executive committees. I have also served on the space, undergraduate and graduate committees, several qualifying exam committees, and ad-hoc committees for graduate recruitment and graduate review.
As part of my service on the computer committee, I help set policy and acquire software and hardware. I work to obtain discounted or free software and hardware for the department, I wrote proposals requesting internal funding for a computer cluster.
As part of my service for the graduate committee, I helped write Dept. of Ed. GAANN proposals requesting funding for graduate fellowships. When this program was funded I worked to recruit GAANN fellows by hosting their visits.
I am active in the state-wide initiatives in the computational sciences. I serve as a member of the research advisory committee of the Ohio Supercomputer Center. I am a regular collaborator to statewide computational sciences initiatives. This includes a large ($60M) Wright Mega Center proposal in which I headed the Advanced Materials thrust, and organized a collaboration between more than 30 researchers at universities throughout the state. I have contributed to several other proposals with the Ohio Supercomputer Center, including two recent requests for a near-petascale massively parallel machines as part of the NSF cyberinfrastructure initiative. I have participated in the state-wide initiatives in computational sciences education associated with the Ralph Regula school. At UC, I formed a group which proposed a Computational Sciences Institute as part of the University's UC|21 initiative.
I serve as a referee for the Physical Review, NSF and DOE. I have served on a DOE committee to review Materials Science and Chemistry research at Los Alamos and Sandia National labs for the BES.
As part of my greater impact activities for the NSF, I distribute several codes on my web page, including maximum entropy and dynamical mean field quantum Monte Carlo codes which are now widely used by other researchers.
