Letter from DLF Co-Directors
Hal C. Lewis, Ph.D. & David Margulies, M.D.

The overarching goal of the Dan Lewis Foundation for Brain Regeneration Research (the DLF) has been, for the past five years, to support biomedical and biotechnological discoveries that will bring the promise of regenerating and repairing the seriously damaged brain into reality. We pursue this goal by sponsoring neuroscientific conferences, publishing a quarterly newsletter, funding early career scientists with the DLF Prize program, sharing promising research nationwide, and posting brain injury information on social media. We strongly believe that biomedical and biotechnological solutions and options for regenerating the seriously injured brain are not only possible but inevitable. The key question is not an “if” question but rather a “how soon” question.


Unfortunately, the current U.S. administration has adopted a somewhat negative stance towards the sciences in general, including the health sciences and biomedical research. With disregard for the way scientific knowledge accumulates, the budget slashers at DOGE, under the direction of the President and his Cabinet, have threatened serious cuts to NIH and NIMH research grants as well as to funds supporting students and faculty in neuroscience and biomedical training programs. Serious cuts to funding have already been made and further reductions can be expected. This short-sighted policy approach will significantly delay important discoveries across various scientific fields. Specifically, for DLF’s constituency, discoveries and related clinical trials that were potentially only a few years away may now be postponed by 5 to 10 years.


The DLF continues to stand in support of neuroscientific and biomedical programs, their students, trainees, faculty, and researchers that have contributed so much to the field of regenerating the damaged brain. If you visit our website—danlewisfoundation.org—you will see “Donate” buttons scattered throughout the content. Please consider a donation, no matter how small or large—to help us continue our work to catalyze progress in brain regeneration research and to urge policy makers to correct course and return to solid support of biomedical and biotechnological advances that will be of so much value to the American public and to persons with serious brain injuries worldwide.

By Hal Lewis December 5, 2025
My daughter, currently nearing completion of a graduate program in counselling, recently introduced me to the term “ambiguous loss”. This term applies to a loss that is unclear and lacks certainty, leaving family members and close friends feeling stuck because it is so difficult to mourn or find closure. One type of ambiguous loss is when the person is physically present but psychologically absent because their personality, memory, cognition, or emotional connection has been altered. Examples might include a family member with dementia, a progressive disease, a severe emotional disorder, or substantial brain injury. A second type of ambiguous loss is when the person is psychologically present but physically absent. This could include a missing person due to a natural disaster, a long- term incarceration, a kidnapping, or severe estrangement from the family. This type of loss can lead to intense confusion, frozen grief, and a prolonged sense of helplessness.

Marchell is an engaging and energetic middle-aged man who was enthusiastic about being interviewed for the DLF newsletter. He is an activist working to promote the rights and well-being of persons in the brain injury community, with a particular emphasis on helping persons with brain injury who are incarcerated or have been released from prison. Marchell is a successful businessman, proud of the company he co-founded--the Association of Young Business Owners (AYBOS), a marketing company in the Denver, Colorado area. He also works for Well Power (Denver’s Mental Health Center system) as a Zero Suicide Certified Peer and Family Specialist.  Marchell is clearly a man on the move to get a lot of positive things done. But this wasn’t always the case. Marchell spent much of his younger adult life incarcerated himself for a variety of crimes including robbery and assault. He had a history of recidivism following multiple releases.
