  • Aman Khurana

    Aman Khurana

    Fellow in Radiology

    Current Research and Scholarly Interests My research interest focuses on cellular imaging and MR imaging. My current projects involve evaluations of a FDA approved iron oxide contrast agent, ferumoxytol, for in vivo tracking of stem cell transplants and immune cells. The goal of these cellular imaging techniques is to non-invasively monitor stem cell mediated tissue regeneration and related immune rejection processes. Keeping the translational potential of this agent in mind, we ultimately aim to translate these novel technologies to the clinic.

  • Mary Ellen Koran, MD, PhD

    Mary Ellen Koran, MD, PhD

    Resident in Radiology

    Bio Mary Ellen grew up in Annapolis, Maryland. She attended college at Duke University, where she majored in Biomedical Engineering with a minor in Chemistry. After graduation, Mary Ellen moved to Nashville, Tennessee to join the Medical Scientist Training Program (MSTP) and earned her combined MD/PhD at Vanderbilt University. She completed her PhD in Human Genetics in the laboratory of Dr. Tricia Thornton-Wells, where she studied the radiogenomics of Alzheimer’s Disease. She developed a pipeline of tools to analyze and quantify images from MR and PET images, which she then used as quantitative traits in genetic analyses to tease apart the etiology of Alzheimer Disease. She is continuing her quantitative MR and PET imaging research with various mentors across Stanford.

    Outside of radiology, Mary Ellen is excited about curriculum development, wellness, mentorship, and leadership. She developed and co-leads the RadCombinator curriculum for protected research time for radiology residents, co-leads the radiology wellness committee, for which she secured funding for a resident wellness program, is a member of the GME Women in Medicine Leadership Council, and is co-chair of the GME Women in Medicine Community Development committee. She is also an active mentor through the Women in Medicine Mentorship Program and the Stanford Women Association of Physician Scientists (SWAPS).

    Outside of work, Mary Ellen enjoys swimming with the Stanford Masters' team, shopping farmer's markets, mountain biking, and hiking the amazing trails around Northern California, all with her husband Cody. They also love playing with their dog, Bowser.
