Ethan Pratt, Head of Engineering at SandboxAQ’s AQMed division, joins Tai-Danae Bradley for a conversation about building heart-health technology that can meet clinicians where they are: in the fast, messy reality of the emergency room.

In this episode, Ethan explains AQMed’s work on magnetocardiography, a technique designed to capture the heart’s magnetic signals and help address one of medicine’s toughest everyday challenges: evaluating chest-pain patients in the ER’s diagnostic “gray zone.” He shares why the team has focused so intensely on real hospital workflows, how an “algorithmic shield” helps separate the heart’s signal from ambient magnetic noise, and why getting prototypes into real clinical settings matters more than waiting for perfection in the lab.

The conversation also traces Ethan’s unconventional path into medtech, from rebuilding a 1967 Camaro and studying physics at Cal Poly to earning a PhD at Cornell and eventually discovering that his strengths lay not in abstract theory alone, but in building experiments, devices, and teams that work in the real world. Along the way, he reflects on math anxiety, interdisciplinary collaboration, and the guiding principle that has shaped both his career and his leadership style: start with what you know.

In our next episode of the fAQ podcast, Tai-Danae Bradley sits down with SandboxAQ's Eneko Axpe to explore the creative and resilient mindset required to navigate and lead in deep tech. Innovation at the edge of physics demands more than technical brilliance; it requires the ability to communicate complex ideas, recover from massive failures, and foster healthy, high-performing teams. Eneko shares his incredible journey from a humble upbringing in Bilbao, Spain, where his mother worked as a cleaner. Thanks to accessible, high-quality public education, he was able to follow his passion and eventually become the first Basque physicist at NASA.

Eneko’s path is a testament to the power of resilience. He opens up about the terrifying (and now hilarious) story of his very first PhD experiment, where a broken glass vial led to the accidental creation of a radioactive living cell culture—resulting in an eight-hour lockdown with his PI. He explains how he bounced back from that disaster, adopting a philosophy from an early mentor to "stand up when you fall" and to treat life's massive obstacles like tsunamis to be surfed. By eventually swapping the glass for metal, his experiment ultimately led to a publication in Nature Physics and a spot at Oxford University.

We also explore his approach to leadership, deeply influenced by a mentor at Stanford who taught him that a leader's true priorities are ensuring their team is growing and happy. Finally, Eneko illustrates that the best deep tech innovators are often polymaths. He walks us through his 15 years in science radio, writing a hit theater play called "Quantum Adventures" that explains quantum physics to kids using Schrödinger's cat, and his mind-blowing invention of "electro cooking," which uses electrical resistance to cook a kilo of meat in just eight seconds.

In this episode of the fAQ podcast, Tai-Danae explores the emotional and intellectual rigor required to solve impossible problems in Deep Tech with Tiffany Callahan, who was a Machine Learning Research Scientist at SandboxAQ before starting her current role at Manas AI as a Principal Machine Learning Engineer. Tiffany is a computational biologist with a fascinatingly unconventional background. From testing the melting point of Tupperware in her family's fireplace, to conducting behavioral experiments on her triplet siblings, her unquenchable curiosity has driven her since childhood.

Tiffany walks us through her journey of completing a 752-page dissertation at the University of Colorado Anschutz, inspired by her grandfather’s wisdom that “knowledge is the one thing that no one can take away from you”. We dive deep into her work at SandboxAQ, where she led a team building causal virtual cell models from first principles to understand gene expression dynamics.

Because Deep Tech demands that we operate in uncharted territory, Tiffany opens up about the immense pressure of the work. She shares the brilliant concept of “Rubber Duck Science” and explains why true Deep Tech leadership requires radical vulnerability. Tiffany recounts a recent moment where she cried in front of her team out of frustration, admitted she didn't know the answer, and watched as that raw honesty empowered her team to solve a two-week coding problem in just two hours. Finally, she shares her deeply personal ultimate dream: to use biology, AI, and digital patterns to proactively solve mental health crises before people even know they are struggling.

The fAQ Podcast is back from hiatus! In our first episode of season 3, Tai-Danae explores what it takes to lead and innovate at the bleeding edge of deep tech with SandboxAQ's Stefan Bogdanovic, Strategic Innovation Lead on the AQMed team. Moving from abstract scientific concepts to building real-world medical products requires a complete shift in mindset, and Stefan walks us through exactly how he navigated that transition.

Stefan’s journey is a masterclass in resilience, starting from his childhood in Serbia during the turbulent 1990s. Originally determined to be a pure theoretical physicist, he opens up about his early battles with imposter syndrome in a dry, highly mathematical educational system that lacked psychological safety. We dive into his evolution from an academic holding the unofficial title of "Chief Morale Officer" for his team at Harvard, to a deep tech leader navigating the messy reality of product development.

Stefan shares hard-hitting leadership lessons from SandboxAQ, including the pivotal moment his team’s three-year project on a magnetocardiography device failed its first clinical trial at UCSF after picking up interference from elevators and laptops. He explains why failing early is a necessary gift in deep tech, how startups often get product strategy backward by prioritizing tech over the application, and why technical leaders must be willing to strip away their professional ego and identity to truly solve a problem.

Welcome to season 2 finale of fAQ! For this season, Tai-Danae and Adam focused on a single topic: What is actually happening inside a quantum computer? By the end of this season, you'll have a better understanding of the "how" of quantum computing. So get ready to go beyond the theory and dig into what's actually going on these machines that harness the fundamental forces of the universe! In this sixth episode, we continue our exploration into DiVincenzo's fifth criterion for functional quantum computers: "Measurement of individual qubits". Specifically, we dig into what it means to "measure" something, in both the everyday context and in the quantum world. You might end up being surprised how similar those are and how not-strange measurement is in the quantum context...well at least some parts of those measurements! Oh, and we talk about how you, yes YOU, can work towards winning a Nobel Prize using the fAQ comment section ;-) Want to get in touch?
