Walter Kowtoniuk


Walt is the father of two and spends his days playing with is kids, teaching them about the world, and having fun watching them grow up. Walt is also passionate about making a difference for patients. He spends his days focused on genetics and genomics and the insights they bring into disease biology. Walt works where science meets business and strategy, enabling insights from the lab to become the next generation of medicines that can change lives. He is enthusiastic about launching companies with emphatic, truly patient-centric cultures that effectively and efficiently execute drug discovery. He places priority on taking the time to listen to the patients whom we endeavor to help, recognizing that the value we aim to create is defined by the magnitude of the difference we can make in their lives.

Brett S. Abrahams


Dr. Abrahams is a neuroscientist, geneticist, and drug hunter with experience developing therapeutics and building startups. He is the founder and President of Heppinn Biosciences, a consultancy practice launched to support venture investors, foundations, and biotech companies diligence opportunities, develop drugs, and start biotech companies. He’s also an Advisory Board Member for Autism Speaks, FAST (Angelman Syndrome), and Accelerator Life Science Partners.


Prior to launching Heppinn, Dr. Abrahams served as Executive Vice President of Research and Development of Magnolia Neurosciences. The company was founded to develop novel therapeutics for neurodegenerative disorders and built out around investment from Arch, Pfizer Ventures, Eli Lilly, and others. Dr. Abrahams joined Magnolia from Ovid Therapeutics, leaving as Senior Director and Head of Pre-Clinical Biology. While there, he helped to move multiple autism and epilepsy-related assets into the clinic and was part of the team that showed clinical benefit of Gaboxadol (OV101) in Angelman Syndrome and Soticlestat (TAK935) in Dravet Syndrome.


Prior to this, Dr. Abrahams was full-time faculty with an independent laboratory at the Albert Einstein College of Medicine, where he retains an adjunct appointment. His lab applied genomic strategies to identify novel disease genes and then studied the molecular, cellular, and behavioral consequences of identified variants in disease models and patients. He was also closely involved in the development of the Simons Foundation’s SFARI Gene, an autism-focused knowledge base for researchers and clinicians. His research, published in numerous high impact journals including Cell, New England Journal of Medicine, Nature, and Science Translational Medicine, has been cited more than 10,000 times.

Shafali Jeste


A Board-certified pediatric neurologist, Dr. Jeste focuses on developing methods to improve precision in the diagnosis and treatment of neurodevelopmental disorders. She is a prolific researcher whose lab has defined early predictors of autism in at-risk infants, and she has authored and contributed to more than 200 journal papers, editorials, chapters and abstracts. In 2019, she was awarded the Presidential Early Career Award for Scientists and Engineers for her research in early predictors and intervention for genetic neurodevelopmental disorders.

Dr. Jeste holds several national and international leadership positions including the Board of Directors of the American Brain Foundation, Board of Directors of the National Organization for Rare Disorders and the Board of Directors of the International Society for Autism Research. She also is Co-Founder of ACEing Autism, a national nonprofit that uses tennis to help children with autism connect, grow and develop.

Dr. Jeste earned her bachelor’s degree in philosophy from Yale University before obtaining her medical degree from Harvard Medical School. She completed an internship, residency and a fellowship in behavioral child neurology at Boston Children’s Hospital.

Dr. Jeste joined Children’s Hospital Los Angeles in 2021 as Chief of the Division of Neurology. In this role, she oversees clinical care delivery and quality, strategic planning, recruitment and program development.
