The project is to build and installed 2 different state of the art SPECT-CT Medical Imaging (MI) clinical scanners & install in preclinical setting to study on human & animal subjects. The scanner specification has many unique complex mechanical & imaging features. There were many engineering challenges solved in order implement all the products unique features specified in the proposal. The multimillion-dollar budgeted project team size is 12 included MD, physicist, scientist, & engineers. My excellent hands-on experience in mechanical assembly & engineering knowledge resulted to assembled & installed two novel PET-CT MI scanners.ACCOMPLISHMENTS:Designed, built, & installed two different SPECT-CT MI clinical scanners meet with IRB & FDA standard Assembled & installed PET-CT MI clinical scannersInvented variable Slit-slats collimator for SPECT MI clinical scannerInvented pinholes collimator adaptive mechanism for SPECT MI clinical scannerManage R&D lab daily operation in cross-functional team environmentEXPERIENCE: Mechanical Engineering:Draw product concept & definitionProduct architecture, design, & 3D CAD Assembly model: Solidworks, AutoDesk InventorExecute design evaluationPerform thermodynamic, finite element, fail-safe & structural analysesDevelop assembly instruction & manufacturing work instructions process2D Mechanical drawings: Technical drawings with Geometric Dimensioning & Tolerancing (GD&T) Manage production assemblyResearch scientist & applied physicist:Explore, review, & assess maturing technologiesPlan & conduct NEMA standard calibration experimentsPerform MATLAB simulations studies Process experimental data & analyze to evaluate system performance Prepare & present research grant proposals, & progress reportsSystem maintenance, trouble shooting, & repairNegotiate & influence with supplier for delivering materials on time with competitive pricingPublic speaking & present research finding in conferences

The project is to build a dedicated cardiac protype Medical Imaging (MI) clinical SPECT-CT scanner. The propose multi-components SPECT-CT scanner specification had complicated mechanical complexities to realize superior image quality compared to available SPECT scanners at that time. As a lead mechanical engineering resolved all engineering problems and designed and single handed built the prototype SPECT-CT scanner. The project team size was 10 which included physicists, simulations scientist, & engineers. Managed instrumentation R&D laboratory daily operation, procurement, & communication with outsourced engineers & technicians.ACCOMPLISHMENTS:Singlehanded designed & built prototype dedicated cardiac SPECT-CT medical imaging scannerInvented full-size reliable operational adaptive Slits-slats collimator system for SPECT-CT imagerImproved team spirit & project motivation 4 Research publications within a year Built prototype system played major role in attracting multimillion research grantEXPERIENCE:Lead mechanical Engineer:Define SPECT-CT MI scanner performance specification Resolve complex mechanical engineering problems 3D CAD design: Auto Desk Inventor & SolidWorksEngineering calculations & analyses Build prototypesPrepare assembly & production instructions2D mechanical drawings with GD&T Communicate with machinist, technician, & outsourced engineering teamAssembling SPECT-CT MI clinical scannersResearch Scientist:Perform Zemax & MATLAB simulation studies Built setup to conduct calibration & quality control experimentsPhysics & medical imagingAnalyze collected datasets scientificallyPrepare research grant proposals supporting materialsPresent findings in conferences and symposiums Cardiac SPECT-CT Instrumentation R&D Lab Manager: Manage daily operation, project planning, & schedulingCommunicate across cross-functional team environmentLogistics to meet with the product cost, quality, & on time delivery

The project is to concentrate terawatts laser pulse to micron-size diffraction-limited focal spot and deliver the concentrated laser pulses on Xe/Kr cluster targets inside an ultrahigh vacuum chamber at highly controllable fashion to generate intense laser-like x-rays pulses. Lead laser and x-rays engineer and research scientist to build biggest KrF* ultrafast laser systems in the Midwest and x-rays imaging diagnostic package which consist of x-ray and laser diagnostic instruments. The total floor area of the facility is 1000 foot & laser pulses travel 100 meters through vacuum before it reaches experimental chamber. Further, the system has unique excimer amplifier in the united State of America. The diagnostic package that I designed de novo, built, installed, & operated inside an Ultra Hight Vacuum (UHV) chamber with remote controllable alignments at sub nanometer precision.ACCOMPLISHMENTS:Built Midwest's largest terawatts KrF* ultrafast laser systemInvented a device to focus terawatts laser pulses diffraction-limited focal spot sizeInvented a device to image intense laser focal spotOptimized simultaneous x-ray diagnostic device by factor of 6Developed 10 times faster efficient bigdata analyzing code Design & models attracted multimillion research grants5 Graduate students received Ph.D. from the built systemInvented higher stability kinematic mount for higher mass mirrors EXPERIENCE:Laser & X-rays Lab Manager:Manage daily operation, experimental scheduling, & budget plansMaintain system performance track-record Lead x-rays & laser engineer:Design, build, & calibrateFemtoseconds lasers systemLaser pulse focusing & diagnostic instrumentsUHVX-rays imaging instrumentsSpectrometers & interferometersOperation, maintenance, & repair of laser systemResearch Scientist:Analyze big datasets: IDL, MATLAB, & MathematicaOptical simulations studies: ZemaxDAQ: LabVIEWMentor PhD. candidates PhD. research experiments
