Charles Fracchia: Securing the Bioeconomy

In this episode of Galaxy Balance, I sit down with Charles Fracchia to explore the emerging infrastructure layer of synthetic biology. We discuss the future of secure and scalable bioengineering, the role of community laboratories in accelerating innovation, and how biology is evolving into a programmable technology platform. Charles shares the story behind BioBright, the creation of Bio-ISAC, and the broader challenge of building resilient systems for a world where genetic engineering becomes increasingly accessible. The conversation moves from cyberbiosecurity and open science to AI-driven biological design, scientific culture, and the growing overlap between software engineering and biotechnology. We also explore the long-term future of human enhancement, decentralized science, and how science fiction continues to shape the ambitions of the next generation of builders working at the frontier of biology.

Tyler Todt: Discipline Over Dopamine

What if the most powerful form of human optimization has nothing to do with biotech? In this episode of Galaxy Balance, Cory sits down with Tyler Todt, who has built a platform around physical health, mental resilience, and intentional living. While the world races toward gene editing, AI, and synthetic biology, Tyler focuses on something more immediate: how daily habits, environment, and mindset shape the trajectory of your life. They explore the tension between technological enhancement and human discipline, from fertility and genetic selection to Neuralink and simulated realities. Along the way, Tyler shares how small, consistent changes transformed his health, marriage, and purpose, and why most people fail by trying to do too much at once.

TJ Cradick: Building the Future of Genome Editing

Genome editing has moved from experimental concept to FDA approved medicine in less than a generation. Few people have been closer to that transformation than TJ Cradick. TJ was one of the earliest pioneers in programmable biology, helping shape the field from the era of zinc finger nucleases through the rise of CRISPR and next generation editing systems. As the second employee and Head of Genome Editing at CRISPR Therapeutics, he helped lay the scientific foundation for Casgevy, the first FDA approved CRISPR therapy. Later, at Excision BioTherapeutics, he worked on some of the first in vivo CRISPR therapies targeting latent HIV reservoirs. In this episode, we dive deep into the evolution of genome engineering. We explore the transition from protein engineered nucleases to scalable CRISPR guide libraries, and the growing importance of delivery technologies capable of targeting tissues beyond the liver. TJ explains how off target analysis evolved from primitive assays into massively parallel sequencing pipelines and why the future of gene editing depends just as much on delivery and manufacturing as the editing enzymes themselves. We also discuss the hidden challenges behind FDA approval, the realities of scaling genome editing therapies, the future of in vivo editing, and the ethical questions surrounding human germline engineering. This conversation is a rare look inside the engineering, regulation, and philosophy of one of the most transformative technologies humanity has ever developed. ·       0:00 - Science Fiction to Science Fact ·       0:23 - Cutting Edge of Science ·       0:37 - Introduction to TJ Cradick ·       1:06 - CRISPR Therapeutics and Beyond ·       1:42 - Early Interest in Science ·       2:12 - Academic Journey ·       3:08 - Transition to Biotech ·       4:04 - Zinc Finger Nucleases ·       5:28 - Evolution of Screening Technologies ·       6:48 - CRISPR Libraries and High Throughput Screens ·       8:07 - New Technologies in Gene Editing ·       9:15 - Off-Target Effects and Assays ·       11:23 - Future Opportunities in Gene Editing ·       13:18 - Regulatory Challenges ·       16:24 - Cost Challenges in Genome Editing ·       18:22 - Manufacturing and Delivery Innovations ·       20:14 - Delivery Challenges and Innovations ·       22:30 - Capsid Design and Blood-Brain Barrier ·       24:01 - Viral vs. Non-Viral Delivery Systems ·       27:19 - IP Limitations and CRISPR Variants ·       30:31 - Target Selection for Therapeutics ·       34:03 - Precise Repair Technologies ·       37:03 - Off-Target Effects in Gene Editing ·       42:31 - Genetic Instability in Edited Cells ·       46:20 - Human Germline Engineering ·       49:19 - CRISPR for Viral Cure ·       51:27 - Regulatory Path Improvements ·       54:20 - Balancing Speed and Safety ·       57:03 - Advice for Future Scientists

Nabiha Saklayen: From Physics to Scalable Cell Therapies

What does it actually take to manufacture biology at scale? In this episode of Galaxy Balance, Cory Smith sits down with Nabiha Saklayen, CEO and co-founder of Cellino, to explore the future of cell therapy manufacturing. Trained in physics and biophotonics, Nabiha is applying principles from semiconductor fabrication to one of the hardest problems in medicine: turning powerful cell therapies into scalable, reliable products. The conversation dives into the core challenges of iPSC variability, autologous versus allogeneic strategies, and why manufacturing remains the primary bottleneck preventing these therapies from reaching patients. Nabiha explains Cellino’s approach, combining AI, imaging, and laser-based systems to create a closed, automated platform for cell production. They also explore how AI is reshaping biology, how scientists are evolving into computational operators, and what the future lab looks like as automation and intelligence converge. From Artemis missions to the arrow of time in reprogramming, this episode connects physics, biology, and the long-term future of engineered life.

Noah Davidsohn: Engineering Longevity at the Genetic Level

What if aging is not a collection of diseases, but a system-level failure we can intervene in? In this episode of Galaxy Balance, Cory Smith sits down with Noah Davidsohn, co-founder and CSO of Rejuvenate Bio, to explore a new approach to longevity rooted in gene therapy and systems biology. Noah’s work focuses on treating aging at its source by rebalancing key biological pathways across the body. Instead of targeting one disease at a time, his team is developing combination gene therapies designed to improve function across multiple organs simultaneously. Rejuvenate Bio is currently raising on Wefunder. This is a rare opportunity to invest in a scaling biotech on the same terms as their VC partners.
