Yimin Shen, PhD
Research Associate

Dr. Yimin Shen is the Research Associate and Chief MR operator who is responsible for the day to day operation and maintenance of the 7T system. He has a Ph.D. in Physical Chemistry and 10 years of solid-state high resolution NMR experience and has worked in small animal MRI/MRS and clinical MRS. He brings a physical chemistry perspective to bridge the gap between medical researchers and MRI. Yimin’s MRI/MRS data have been published in many abstracts and papers. He’s currently involved in animal MRI projects including Effects of P-Glycoprotein Modification on Hydrocephalus; Preclinical Evaluation of Investigational Agents; Preclinical Development of a Novel Targeted Approach for NF1 Malignant Peripheral Nerve Sheath Tumors; PET-CT & MRI Screening and Immunohistochemistry Optimization for Novel Radiotracers. He has collected and analyzed human MRS data for a long-term study of MS with Neurology faculty.

Robin Roberts, B.S.
Senior Research Assistant

Robin Roberts is an MR Technician on the 7T small animal magnet with 17 years of experience in small animal imaging. Her responsibilities are to coordinate and schedule all 7T studies, track billing hours for paid and developmental studies, obtain paperwork for studies (IACUC approval letters, initial contact forms), coordinate DLAR/OEHS inspections, ensure 7T lab in compliance, and maintain organization and cleanliness of the 7T facility. She ensures that the animal (e.g., anesthesia) and MRI data collection needs of new and existing users are met. This involves helping to collectthe data, coordinating projects with Yimin Shen, and training and certifying users in how to collect their data safely. She runs the magnet for all Dr. Berkowitz’s studies and is currently learning how to collect different types of images to be additional support and back up for Dr. Shen.

Farhad Ghoddoussi, PhD
Research Associate

Dr. Ghoddoussi's current research interest includes the use of magnetic resonance imaging (MRI) and spectroscopic techniques (MRS) in studying the neurochemical mechanisms of action of different pharmacological agents such as anesthetics and drugs of abuse. He also has utilized the same techniques to study neuropsychiatric disorders (epilepsy, ALS, schizophrenia, depression) cancer and genetic modifications on the neurochemical profiles in rodent or excised tissues of the human brain.
