👤 About the Guest

Corbin Popp, DMD, grew up in small-town Nebraska around his father's dental office. He excelled in science and math and earned a biochemistry degree with honors from the University of Nebraska.

A Fulbright Scholarship took him to Germany, where he put dentistry on hold for a decade-long career as a professional dancer on Broadway and international stages. Dance taught him to see the body as one interconnected system, and that view now shapes his dentistry. A tooth functions within a bite, a jaw, a skeleton, and ultimately a whole person.

He graduated top of his class from the Arizona School of Dentistry and Oral Health and was named Resident of the Year in his Graduate Practice Residency at the University of Colorado Anschutz.

His practice focuses on ceramic implant surgery, regenerative bone augmentation, and complex Bioesthetic full mouth rehabilitation and jaw stabilization. His surgical work also includes managing root canal treated teeth and poorly healed extraction sites. These sites have historically been called cavitations or FDOJ lesions and are now being studied through newer concepts such as Covered Socket Residuum.

He has completed Level 3 training through the OBI Foundation for Bioesthetic Dentistry, as well as Level 1 dental technician training in dental morphology. That combination reflects his view that bone, implant position, jaw stability, and tooth morphology must all come together to create function, which is why he stabilizes the jaw before restoring the teeth.

He was the first American dentist certified in the Swiss Biohealth Concept, trained under Dr. Ulrich Volz, and later studied Biological Bone Augmentation with Dr. Frank Zastrow. He is currently in advanced postgraduate training with Professor Shahram Ghanaati, whose work in wound healing, regenerative biology, and jawbone healing informs his surgical approach.

On the more controversial questions in biological dentistry, he is careful to separate clinical observation from established science. In his words, "Biological dentistry shouldn't mean less science. It should mean more biology and better science."

🎧 Episode Summary

Emily Gutierrez, DNP, C-PNP, CCN, IFMCP, FMAPS explores the brain-folate connection and the role of cerebral folate deficiency in autism, PANS/PANDAS, and neurodevelopmental health. She explains how folate supports DNA synthesis, myelination, neurotransmitter production, and other critical functions in the brain, while highlighting how blood folate levels may appear normal even when folate availability in the central nervous system is inadequate.

The conversation examines folate receptor alpha autoantibodies and the mechanisms that can interfere with folate transport into the brain. Dr. Gutierrez discusses their significant overlap with autism and PANS/PANDAS, the potential contributions of mitochondrial dysfunction and genomic variants, and the use of the Folate Receptor Antibody Test (FRAT) to identify blocking and binding autoantibodies. She explores dietary, inflammatory, and immune factors that may influence folate receptor autoimmunity and cerebral folate availability.

Dr. Gutierrez discusses folinic acid and prescription leucovorin as strategies to increase folate availability in the brain, including dosing, titration, potential side effects, and factors that may influence treatment response. She explains how higher doses may utilize alternative folate transport mechanisms, why addressing inflammation, infections, and nutrient cofactors may be important, and how restoring adequate folate availability may support language, development, neurological function, and resilience.

🎧 Episode Summary

Christian Navarro-Torres, PhD shares his journey from cognitive neuroscientist and academic researcher to becoming a patient with severe CIRS, biotoxin illness, and extreme environmental hypersensitivity. Drawing from both scientific training and lived experience, he discusses how mold exposure, immune dysregulation, chronic infections, and microbial colonization shaped his understanding of complex chronic illness and led to the creation of CIRS Lab.

The conversation explores the evolving science of CIRS, including HLA genetics, innate immune activation, mycotoxins, transcriptomics testing through GENIE, and the potential roles of mold, endotoxins, beta-glucans, Actinobacteria, and chronic infections in driving persistent symptoms. Dr. Navarro-Torres also examines how nervous system dysregulation, trauma, neuroinflammation, and metabolic dysfunction may contribute to illness severity and recovery challenges.

Dr. Navarro-Torres suggests that recovery often requires looking beyond environmental exposures alone to address microbial burden, immune resilience, metabolic health, sinus health, and physiological repair. He emphasizes the importance of restoring interconnected systems that support long-term healing and improved adaptability.

👤 About the Guest

Christian Navarro-Torres, PhD is a cognitive neuroscientist with formal training in cognitive psychology, neuroscience, language science, and applied data analysis. He earned his PhD in Language Science from the University of California, Irvine, after completing an MS in Cognitive Psychology at Penn State and a BA in Philosophy from the University of Puerto Rico. His research career has included postdoctoral fellowships at Princeton University and at Georgetown University, where his work focused on the intersection between experience-dependent neuroplasticity and clinical assessment in patients with brain damage affecting language and cognition.

He is the Co-Founder of CIRS Lab, the Scientific Director of The CIRS Research Foundation, and a Research Consultant for the Einstein Mission, which investigates erythromelalgia and CIRS.

Christian's recent scientific work extends into environmental health and immune dysregulation, including publications and presentations on biotoxin illness, its multi-system and multi-symptom pathology, and treatment outcomes with a particular interest in how CIRS-related brain changes may contribute to processes of neurodegeneration.

Equally important, his mission is grounded in lived experience. He is a complex, hypersensitive patient who has endured serious microbial colonizations; an underappreciated and often overlooked issue in the mainstream mold illness community; alongside tick-borne and protozoal co-infections. These overlapping comorbidities created a perplexing clinical profile that demanded self-advocacy, where his scientific background became essential to navigating conflicting medical advice and fragmented care.

Drawing from both his expertise and his personal recovery journey, he now provides training for physicians and clinicians on how to identify, understand, and treat those with complex, multi-layered presentations.

🎧 Episode Summary

Joshua Leisk continues the discussion of his systems biology model for ME/CFS, Long COVID, and related chronic illnesses, focusing on how lymphatic dysfunction, sympathetic nervous system dominance, metabolic impairment, and chronic stress responses may contribute to the persistence of complex chronic conditions. He explores the relationships between cortisol regulation, trauma, autonomic imbalance, energy metabolism, and the body's ability to maintain resilience and recovery.

The conversation examines how biofilms, chronic infections, viral reactivation, hypoxia, oxidative stress, and immune system blind spots may interact to drive ongoing symptoms and disease progression. Joshua discusses the potential roles of microbial adaptation, mitochondrial dysfunction, connective tissue disorders, circulatory challenges, and inflammatory signaling in creating self-perpetuating cycles of illness.

Joshua shares his perspective that meaningful recovery requires addressing the interconnected factors underlying chronic illness, including metabolism, nutrient status, autonomic regulation, lymphatic flow, structural integrity, and immune function. He suggests that restoring these foundational systems may help the body regain adaptability, improve cellular energy production, and support long-term healing.

🎧 Episode Summary

Joshua Leisk explores his systems biology model for ME/CFS and related chronic illnesses, explaining that many seemingly different conditions may stem from shared patterns of autonomic nervous system dysfunction, chronic infections, biofilms, oxidative stress, and impaired cellular energy production.

The conversation examines how factors such as viral reactivation, microbiome imbalances, nutrient depletion, heavy metals, and sympathetic overdrive may contribute to illness progression.

Joshua shares that chronic illness reflects interconnected processes within the body that can be reversed when underlying metabolic and physiological dysfunctions are addressed.
