I have completed a Bachelor of Science & Master of Science in Applied Physics & Electronics from Rajshahi University, Bangladesh. I also did a post-graduate diploma in Information Technology (IT) from the same university. After completing my institutional education I started my first job as a field service engineer on Varian Inc. analytical instruments such as UV-Vis, AAS, GC GCMS, LCMS, ICP-MS, etc. At that time I also worked on the service of ThermoFisher Freezer, Refrigerator, Centrifuge, Flame photometer, and some other laboratory instruments. Since my first job, I have been working in the service of instrumentation for over 10 years. Throughout the job duration, I have had the opportunity to work on various laboratory instruments belonging to mass spectroscopy, chromatography, GCxGC, optical spectroscopy, and thermal desorption. As a result, I continue to have the privilege to learn about many contemporary technical and operational matters of laboratory instrumentation. All along the job period, I am privileged to gain practical work experience on instruments from famed instrument brands including Varian, Thermo Fisher, Agilent, Bruker, Scion, Markes International, Randox Toxicology, Kruss, Zurich Instruments, Cole Parmer, Hitachi High Technologies, Perkin Elmer, etc.As a field engineer, I had the opportunity to perform many Installations, Commissioning, Maintenance, Troubleshooting, IQ, OQ, PQ, Validation, Calibration, and Performance Optimization of all types of scientific and analytical Instruments.In addition, I also have got fieldwork experience in the installation and service of GC, Mass Spectrometry, GC-TOF-MS, GC-MS, HPLC, UHPLC, LC-MS, ICP-MS, ICP-OES, AAS, Thermal Desorber, Drop Shape Analyzer, Impedance Analyzer and so on.Finally, I would add that my positions facilitated me to work on some instrument control and data analysis software platforms such as Agilent ICP Expert, SCION CompassCDS, Agilent ChemStation, Agilent MassHunter, Hitachi Chromaster, Markes TOF-DS, Markes ChromSpace, etc.
