What happens when a psychiatrist sits down with a Stanford physics professor to talk about gravitational waves, dark matter, quantum mechanics, and atoms existing in two places at once?
In this episode of No Reason to Get Excited (NRTGE), Dr. Aaron Winkler talks with Stanford Physicist Peter Graham about the strange and fascinating world of modern physics. What starts as a conversation about gravitational wave detection quickly turns into a deep exploration of quantum mechanics, atom interferometry, atomic clocks, dark matter, and the bizarre reality of particles behaving like waves.
Peter explains how researchers are building tabletop experiments capable of measuring incredibly small distortions in space-time, why gravity is surprisingly weak compared to electromagnetism, and how a single atom can exist in two places at once. Along the way, Aaron asks the kinds of questions many listeners are probably thinking themselves, leading to a conversation that feels less like a formal interview and more like two curious minds trying to make sense of the universe together.
This episode is not a simplified science lecture. It’s an intellectually alive conversation about uncertainty, experimentation, physics, and the limits of human intuition.

What does it actually mean to create a molecule that has never existed before?
In this episode of No Reason to Get Excited (NRTGE), Dr. Aaron Winkler sits down with Stanford organic chemist Noah Burns for a wide-ranging conversation about chemistry, creativity, photochemistry, molecular design, and the strange beauty hidden inside organic reactions.
What begins as a discussion about bromination and halogenation quickly expands into something much bigger: the relationship between science and imagination, the role of intuition in research, and how chemists develop entirely new reaction pathways capable of creating highly strained molecular structures.
Noah explains how his lab designs reactions that selectively create one molecular “handedness” over another, why chirality matters in medicine and biology, and how light can be used to drive reactions that would otherwise be energetically impossible. Along the way, Aaron connects chemistry to psychology, creativity, consciousness, traffic systems, human relationships, and even the metaphorical power of molecules like porphyrin.
This is not a technical lecture disguised as a podcast. It’s an intellectually playful conversation about discovery, emergence, energy, and the deeply human side of scientific work.
About the Guest Noah Burns is an associate professor of chemistry at Stanford University specializing in synthetic organic chemistry. His research focuses on developing new chemical reactions, photochemistry, halogenation strategies, strained molecular systems, and the total synthesis of complex natural products. His lab explores how novel molecular transformations can enable discoveries in biology, medicine, and materials science.

Life at the Edge of Equilibrium: Non-Equilibrium Physics, Machine Learning, and the Molecular Machinery of Life | Grant Rotskoff
What if the secret to understanding life lies in the mathematics of systems that can never sit still? In this episode of No Reason to Get Excited (NRTGE), Dr. Aaron Winkler sits down with Grant Rotskoff, Assistant Professor of Chemistry at Stanford University, to explore the breathtaking frontier where statistical physics, computation, and biology collide.
From the unsolved mystery of how ATP, the "spark of life," actually hydrolyzes, to the way muscle tissue self-assembles from molecular ratchets, Grant unpacks what it means to study living systems that are, by their very nature, perpetually far from equilibrium. Along the way, Aaron draws striking parallels between the molecular machinery of cells and the deepest questions of consciousness, attention, and emergence.

Building Brains on Chips: Carbon Nanotubes, Lipid Nanoparticles, and Engineering the Frontier of Neurodegeneration | Rebecca Pinals
What if the most powerful tools for understanding the human brain are the very tiny particles we're learning to build, atom by atom? In this episode of No Reason to Get Excited (NRTGE), Dr. Aaron Winkler sits down with Rebecca Pinals, Assistant Professor of Chemical Engineering at Stanford University and Institute Scholar at Sarafan ChEM-H, to explore the frontier where nanotechnology, neuroscience, and chemical engineering collide.
From carbon nanotubes that glow in the near-infrared, to the "protein corona" that makes biological systems so beautifully unpredictable, to lipid nanoparticles that may one day flush the brain clean of disease, Rebecca walks through how her lab is engineering microscopic tools to crack one of medicine's hardest problems: Alzheimer's disease. Along the way, Aaron and Rebecca dig into why almost everything we know about the brain comes from animals that aren't quite us, how a handful of cells can self-assemble into a working capillary inside a hydrogel, and why the long-overlooked story of lipids may be the missing piece in our understanding of neurodegeneration.

Between Bonds and Forces: Building Monolayers, Twisting Bilayers, and Watching Lattices Move at Trillionths of a Second | Fang Liu
What if the most powerful materials of the future are only one atom thick? In this episode of No Reason to Get Excited (NRTGE), Dr. Aaron Winkler sits down with Fang Liu, Assistant Professor of Chemistry at Stanford University, to explore the cutting-edge world of two-dimensional materials, where single-atom-thick semiconductors stack, twist, and transform in ways that could redefine electronics, quantum computing, and energy technology.
From a childhood in Northeast China where she barely made it into chemistry at Peking University (the major with the lowest score threshold), to inventing a gold-based exfoliation technique that won her a faculty position at Stanford, Fang walks through how her lab creates moiré superlattices at centimeter scales, uses ultrafast lasers to make atomic lattices twist in trillionths of a second, and collaborates with Cornell and SLAC to watch quantum materials dance. Along the way, she and Aaron dig into why Scotch tape won a Nobel Prize, what lives between van der Waals forces and chemical bonds, why twisted bilayer graphene becomes a superconductor at exactly 1.1 degrees, and how sometimes the best career path is the one where you take the only offer you get.
About the Guest Fang Liu is an Assistant Professor of Chemistry at Stanford University, where her lab develops scalable methods for creating and studying two-dimensional materials and their artificial structures. She invented a gold-based exfoliation technique during her postdoctoral work at Columbia University that enables the production of large-scale, high-quality moiré superlattices, millimeters to centimeters in size, with nearly perfect yield. She received her B.S. in Chemistry from Peking University in Beijing in 2010, her Ph.D. in Chemistry from the University of Pennsylvania in 2015 (where she studied photochemistry of Criegee intermediates and atmospheric radicals under Prof. Marsha Lester), and was a DOE postdoctoral fellow in Prof. Xiaoyang Zhu's group at Columbia University from 2016 to 2020, where she switched fields from gas-phase spectroscopy to solid-state 2D materials. Her research uses ultrafast spectroscopy, electron diffraction, and light-induced control to explore quantum properties in twisted materials, with recent work (published in Nature in 2023) demonstrating photo-induced twisting motion in moiré superlattices. Before joining Stanford in 2020, she applied to 92 universities for faculty positions.
Living Drug Factories: Bioelectronics, Wireless Power, and the Implantable Future of Medicine | Siddharth Krishnan
What if curing a chronic disease looked less like a daily pill and more like a tiny, wireless implant of living cells that quietly produces your medicine on demand? In this episode of No Reason to Get Excited (NRTGE), Dr. Aaron Winkler sits down with Siddharth Krishnan, Assistant Professor of Electrical Engineering at Stanford University, to explore the rapidly evolving frontier of bioelectronic medicine.
From his grandfather's soldering iron in Chennai, to a New Yorker article on John Rogers that changed his life, to a battery-free implant that has cured diabetes in mice for months, Siddharth walks through how his lab is engineering devices that combine living cells with thin-film electronics to deliver biologic drugs continuously, sense biomarkers in real time, and reshape what treatment for chronic disease can even look like. Along the way, he and Aaron dig into why oxygen is the hardest problem in implantable cell therapy, why the solution borrows physics from fuel cells, RFID credit cards, and photosynthesis, and why the future of medicine might involve all of us walking around with our own tiny bioreactors under the skin.

Periodic Table as a Playground: Quantum Materials, Molecular Intercalation, and the Chemistry of Crystals That Change Color | Lilia Xie
What if the technologies of the future are built from materials we haven't even made yet? In this episode of No Reason to Get Excited (NRTGE), Dr. Aaron Winkler sits down with Lilia Xie, Assistant Professor of Chemistry and the Princeton Materials Institute at Princeton University, to explore the world of quantum materials, where the arrangement of atoms, the energy of electrons, and even the angle between atomic layers can transform a material from insulator to metal to superconductor.
Lilia takes Aaron on a wide-ranging tour through two-dimensional materials, transition metal dichalcogenides, moiré superlattices, and the frontier of molecular intercalation, where her lab is slipping organic molecules between layers of inorganic crystals to tune properties no periodic table combination could produce on its own. Along the way, they dig into how electrons flow through metals, why a crystal turned from red to black in her grad school lab, what unpaired electron spins have to do with your fridge magnet, and why sometimes the most surprising discoveries come from simply cooking up something new and watching what happens.
