Office of Fellowship Training (OFT)

OFT Mission

The mission of the Office of Fellowship Training is:

  • To support and promote a productive and fulfilling research training experience in the NIMH Intramural Research Program
  • To encourage career planning and guide career management through trainee use of Individual Development Plans (IDPs)
  • To provide programs and services to assist trainees in discovering and clarifying career choices
  • To provide opportunities and to encourage trainees to build a professional skill set which enables them to become world leaders in academic and non-academic careers

Come visit our booth and speak with an OFT staff member about the fellowship and training opportunities we offer at the NIH/NIMH. We will be at the following scientific meetings: Annual Biomedical Research Conference for Minority Students (ABRCMS), The American Society for Pharmacology and Experimental Therapeutics (ASPET), Society for Advancement of Chicanos/Hispanics and Native Americans in Science (SACNAS), Society of Biological Psychiatry (SOBP) and Society for Neuroscience (SfN).

Trainee Successes: Past & Present

Mark Eldridge, Ph.D. Dr. Mark Eldridge joined the Section on Neural Coding and Computation at NIMH as a postdoctoral fellow in 2011 under the direction of Dr. Barry Richmond. During his time as a postdoc fellow Dr. Eldridge’s research interests included perception, recognition and categorization of visual stimuli in temporal lobe (2011-2016) and reversible silencing using DREADDs to investigate neural substrates of reward valuation (2016-2019). In December 2018, after completing his post-doctoral fellowship, Dr. Eldridge became a Staff Scientist in the Laboratory of Neuropsychology under the direction of Dr. Betsy Murray (NIMH). His research focuses on understanding how the perceptual and reward value systems interact in the formation of visual memory in non-human primates. He uses traditional techniques (e.g. aspiration lesions & pharmacology), combined with the application of modern molecular tools (e.g. chemogenetics) to explore the neural substrates of recognition, categorization and stimulus value assignment in the inferior temporal lobe and inter-connected regions.
