I received my Ph.D in Quantum Science and Energy Engineering in 2008 from Tohoku University, Japan. During my graduate program, I worked on semiconductor small animal PET in both hardware and software areas and performed feasibility study of a transformable gantry for novel PET systems. I carried out research on modifying geometrics of positron emission tomography systems together with characterization of the front-end of position sensitive CdTe detectors. After holding assistant professorship at Tohoku University, I joined Rush University Medical Center as research fellow in May 2009 where I was responsible for the front-end detector development of a cost-effective dedicated Cardiac SPECT system based on NaI(Tl) and conventional PMTs. I transitioned to industry and joined Radiation Monitoring Devices Inc. in 2011 for 3 years as staff scientist where I initiated and lead multiple projects including the laser-induced optical barriers technology (LIOB), and prototype intra-operative radioguided surgical probe that was built and tested on rabbits.Other projects I was heavily involved in are development and characterization of photon counting detector including SiPM-based detectors as well as pixelated semiconductor devices and scintillation detectors such as CZT, CdTe, LaBr₃ and CsI, etc.  I joined HMS as faculty in March 2014 and put together a physics instrumentation laboratory for radiation detection and imaging at MGH Radiology. The main theme of the Sabet Lab is development of novel detector technologies for nuclear medicine and x-ray imaging applications including PET, SPECT, and CT together with radiation-based intra-operative imaging probes.
