Bella’s Story

Though brain injuries usually lead to a range of physical, cognitive, and emotional issues, every person who incurs a brain injury experiences a unique set of symptoms as well as both short-term and longer-term outcomes. This is true whether the brain injury is classified as mild, moderate, or severe. Therefore, it is important to take every brain injury seriously and to get medical attention as soon as possible to prevent further damage and to improve outcomes. Bella Kellis, at age 14, experienced a traumatic brain injury. In her own words, Bella, now 16, shares her story. 

From a very young age, I believed that prioritizing education and developing self-discipline was the key to success. At just five years old, I’d already fallen head-over-heels in love with school, I loved acquiring knowledge about the world and experiencing everything I could. That thinking was abruptly changed and put on hold when I was fourteen and sustained a traumatic brain injury.


It was mid-summer at Lake Murry in 2020. I was fifteen feet up in a pine tree, ready to use the rope swing to jump into the water, but things did not go as planned. Instead, I fell directly onto my head at the foot of the lake. At the time, my dad understood the potential severity of the accident and rushed me to the doctor, but they simply glued my lip together and sent me home. I walked out of urgent care with minimal bruising and no stitches. They assumed I was okay because I showed no apparent external physical damage beyond a torn lip, but what they didn’t see or understand was that I walked out an entirely different person. I thought maybe all I needed was some sleep and I’d wake up to the person I was before, but I was terribly wrong. 

"I was unpredictable, defensive & exhausted. I felt out of control and I knew I was a different person."

My sophomore year of high school started differently. Following the accident, I had multiple weekly emotional breakdowns and could not handle stress. I returned to school and found it almost impossible to stay awake in class (narcolepsy: a rare long-term brain condition that can prevent a person from choosing when to wake or sleep). I had always easily juggled sports, straight-A academics, friends, and family. However, I could no longer read without developing an instant headache. I felt abnormal anger, sadness, and mood swings daily. Maintaining healthy relationships was almost impossible.

By the end of my sophomore year, I was unpredictable, defensive & exhausted. I felt out of control and I knew I was a different person. My family could not comprehend how the girl who memorized her multiplication tables at age five was the same person sobbing over algebra 2, refusing to identify as a “math person” ever again. All of us were bewildered by the change. I spent the last two years rebuilding my academics, relationships, attending doctor appointments and therapies. Working to rebuild the life I once had is a struggle. The traumatic brain injury temporarily paused my development and left me trying to achieve what had been so simple before. I still face many obstacles in my day-to-day life, but I am making great progress. I have worked hard to compensate for the effects of my condition. It is an ongoing journey with plenty of adaptations, but the process allows me to know myself better than ever before.

Of the many struggles caused by my injury, I found the most detrimental was my loss of identity. When you cannot live your life as the person you once were, life as you know it, changes. Losing trust in yourself affects every area of your life, especially interactions with others. How can you build a strong bond with another individual if you do not have one with yourself? How could one accomplish simple, everyday tasks like communicating and reasoning with another person when the ability to communicate with myself was poor? My traumatic brain injury triggered a loss of self and disadvantaged me in every area of my life, including social, family, and academic settings.


My traumatic brain injury has transformed my attitude toward my accomplishments. It was a glimpse of reality, a reality of a world where we all have an expiration date, and in a split second, you could lose everything you have worked so hard for. All that stays with us is our experiences and those of the individuals we have impacted throughout our lives. Therefore, we don’t have time to waste on mindless activities that aren’t making a difference or bringing joy to our lives. Given the age of my injury, “brain plasticity” has allowed for what I believe is a miraculous brain recovery. However, I recognize that everyone does not share that fortune. I aspire to one day alter society’s current treatment and understanding of brain trauma by making that the focus of my studies in college and career beyond.

Graham Dempsey, Ph.D., is a founder and Chief Scientific Officer (CSO) at Quiver Bioscience, a Cambridge, Massachusetts-based biotechnology company focused on the development of medicines for disorders of the nervous system. Dr. Dempsey and his team are working to develop treatments for some of the most challenging unsolved medical issues patients and their families face. Using advanced technologies in human stem cell biology, optogenetics, machine learning, and drug screening, progress is being made to develop medicines that will one-day treat conditions that have been largely untreatable. As the lead scientist for Quiver, formerly Q-State Biosciences, Dr. Dempsey enjoys working with world-class teams to invent, develop, and apply cutting-edge technologies to solve the most difficult challenges in biopharma for the betterment of patients. Dr. Dempsey’s inspiration to dedicate his professional life to science and medicine started at the early age of seven with the tragic loss of his father to an aggressive form of cancer, an experience that has deeply motivated him to this day. He completed his undergraduate studies at the University of Pennsylvania and his doctorate at Harvard University. As a graduate student in the biophysics program at Harvard Medical School, he co-developed ‘Stochastic Optical Reconstruction Microscopy’ or STORM , a light microscope with the ability to resolve nanometer (billionth of a meter, e.g. a hair is 100,000 nanometers thick) scale details of biological materials, an achievement that had been thought to be impossible for over a century. STORM has enabled what researchers call ‘super-resolution imaging’ for visualizing the intricate details of life’s most fundamental unit, the cell. Understanding the inner workings of a cell provides a path to a deeper understanding of the ways in which life is constructed and diseases can manifest. The technology was commercialized by Nikon Instruments for researchers worldwide. Dr. Dempsey left academic science to join Q-State Biosciences as the first hired employee with the goal of bringing advanced technologies developed at Harvard to the study of the brain. The brain, arguably the most complex structure in the known universe, works through electrical communication between brain cells or neurons. This communication is disrupted in all brain disorders but has been near impossible to study for the purposes of effectively developing medicines. Dr. Dempsey and his team over the course of ten years built a technology system that creates human brain models from patient stem cells (i.e. a ‘disease-in-a-dish’) and converts electrical activity of those brain cells into light signals that can be detected with ultra-sensitive microscopes. The resulting signals are analyzed using machine learning to find the patterns of how electrical activity is altered in disease, which can be used to find medicines that correct those changes. The team at Quiver is deploying this technology to take on previously untreatable brain conditions, including rare genetic diseases, such as certain seizure and neurodevelopmental disorders, to common conditions, such as chronic pain and Alzheimer’s disease. Dr. Dempsey’s passion outside of science starts with his family, his wife (and high school sweetheart) and three young daughters, be it traveling the globe to experience new cultures (or simply stare at the ocean), cooking elaborate meals on a Saturday evening, night-time reading of novels to his daughters, or attending live music around Boston. As a native of NJ, he celebrates his roots with visits to family near the Jersey Shore and, whenever possible, attendance at Springsteen concerts and Giants games. Dr. Dempsey is an avid student of history’s great entrepreneurs, spending the sparse remaining minutes of the day reading biographies and listening to podcasts, looking to extract every bit of learning towards taking on the challenges of building a great business while staying true to his family, his Quiver teammates, and his professional mission.
