Caleb Harvey
Founder & Scientist
​Caleb's direction was set at an early age, growing up witnessing his mother struggle with chronic illness. Later in college a motorcycle accident, ICU visit and subsequent traumatic brain injury left him unable to read. Despite undergoing extensive rehab therapy and continuing premed collegiate coursework, he went on to graduate in 5 years. After undergrad he worked as a 911 paramedic provider in and out of the hospital setting learning the US medical system.
These formative experiences led him to want better medicine for humanity. Transitioning to working in a clinical space startup and entering graduate school, he encountered a recurring problem and designed a solution, the flagship therapy rNavex. He currently continues working to create and develop systemic cures for the individual.

Research Scientist
Allen Sonstein, MD
Scientific Advisor
Dr. Allen Sonstein is a board-certified internal medicine physician with over five decades of experience specializing in adult and geriatric care. He received his medical degree from Jefferson Medical College and completed advanced training in both internal medicine and family practice. After beginning his career providing care in medically underserved areas of Texas, Dr. Sonstein went on to establish a long-standing internal medicine practice in Austin, where he cared for patients for more than 40 years.
​
Throughout his distinguished career, Dr. Sonstein has held leadership roles such as Chief of Staff and medical director at South Austin Hospital. He has also contributed extensively to medical education through faculty appointments at institutions including The University of Texas Medical Branch, UT School of Nursing, and Dell Medical School. Known as a devoted community leader and volunteer, he provides care at the C.D. Doyle Clinic for the homeless and participates in numerous medical mission trips across Central America.
​
He has been honored with teaching and humanitarian awards and holds memberships in organizations including the American Geriatric Society and Texas Medical Association. Currently, Dr. Sonstein is actively engaged in clinical research focusing on vaccines, Alzheimer’s disease, and infectious diseases through numerous industry-sponsored trials. He remains deeply committed to advancing patient care, clinical research, and the education of future healthcare professionals.
Tyler Goralski PhD
Scientific Advisor
Dr. Tyler Goralski began his tenure at DEVCOM Chemical Biological Center in 2012 as a research technician in the Biosciences Division. Shortly thereafter, he went on to pursue his Ph.D. as a Department of Defense SMART scholar. He received his Ph.D. from The Pennsylvania State University in Biochemistry, Microbiology, and Molecular Biology, where he focused on the characterization and optimization of a unique group of antibiotics that specifically inhibit a novel and essential bacterial pathway known as ribosome rescue in the biothreat agent Francisella tularensis. He subsequently identified and characterized a backup rescue pathway in F. tularensis known as ArfT, which functions to resolve non-stop complexes when trans-translation is inactive.
Upon completion of his doctoral work, Dr. Goralski returned to DEVCOM CBC to support the Threat Agent Science Division and developed several in vitro assay systems used to predict the toxicological effects of agents of concern. His focus was on the development and implementation of human organ-on-a-chip technologies to characterize the toxicity of chemical and biological threat agents via global multi-omics analysis.
Currently, Dr. Goralski serves as the Chief of the Molecular Toxicology Branch. The team deploys a battery of toxicological-based tools to characterize emerging threats, to include functional organ chip models, cell receptor-based screens, electrophysiology, neurotoxicity models, zebrafish, histology, and bioprinting. In his spare time, Dr. Goralski lectures for the Johns Hopkins Biotechnology Master’s Program; teaching courses in infectious disease, molecular biology, and advanced cell biology.
