Recently Completed Research Support:

DOE/Office of Science: BER (PI: P. Hahnfeldt; Consultant: R. Sachs)   7/2009 – 7/2013
Intercellular Interactions during Tumor Progression: Implications for Low-Dose Risk.
The goal of the grant is to analyze the implications of intercellular interactions on ionizing-radiation induced cancer risks at low and very low doses. Such interactions call into question a standard microdosimetric argument for risk linearity; a key question is to estimate in which direction the possible deviations from linearity may be.

NASA | NSCOR 04-0014-0017 / NNJ04HJ12G / NNJ06HA28G (PI: L. Hlatky; Asst. Dir.: R. Sachs)   10/1/2004 – 10/31/2010
NSCOR: Solid Tumor Risk Estimation: Incorporating Intercellular Interaction Effects.
The goal of the overall grant is to study radiation solid tumor risk to astronauts on an extended space mission, experimentally and mathematically. A Berkeley subcontract (PI: Sachs) emphasizes microdosimetry and the role of chromosome aberrations in carcinogenesis.

NIH | RO1 GM 068423 (PI: R. Sachs)   7/1/2003 – 6/30/2008
Updating Chromosome Aberration Simulator (CAS) Software.
Main goals were to make CAS freely available to the radiation cytogenetics community and to extend it.

DOE | DE-FG02-03ER63668 (PI: R. Sachs)   09/1/2003 – 8/31/2007
Modeling Interellations Between the Bystander Effect, Chromosomal Instability, and Radiation Risk.
The major goal of this project was to model signaling in the radiation bystander effect and low-dose cancer risk, using mathematical formalisms and computer simulations.
