Radiochemistry Technologist 3
Biography
I was born in Iran-Tehran. I have a master degree of Chemistry from Sacred Heart University in Fairfield CT, and a Master degree of Molecular Cellular Biology from University of New Haven in West Haven CT. I worked three years at Bayer Pharmaceuticals in West Haven CT as an analytical chemist before coming to Yale Medical School. I have been working for 19 years in the department of Radiology and Biomedical Imaging, PET center chemistry department. I am involved in synthesis, radiolabeling, and purifying Radiopharmaceutical ligands for human and animal PET imaging used for applications in neuro and cancer imaging.
I am a compassionate laboratory technician trained to handle issues and remain level- headed. Reliable and a hard worker with great interpersonal and team collaboration skills. Expertise in cleaning, maintaining and setting up lab equipment. Skilled at using laboratory expertise and chemical knowledge to help and train professionals make accurate decisions and support the lab objectives. Manage equipment, supplies and chemicals efficiently to coordinate smooth laboratory operations.
I enjoy being among my family and great friends, gym, music, online searching, great movies and cooking. I am lucky to be a part of a state-of-art radiochemistry department and working with talented and dedicated personals.
