Welcome to the Han Lab!

The Han Lab is a Magnetic Resonance and Quantum Information Science laboratory primarily affiliated with the Department of Chemistry at Northwestern University, with additional ties to the Applied Physics program. Our offices and laboratories are located within Northwestern’s Chemistry of Life Processes (CLP) Institute.We are motivated by fundamental questions in life-science chemistry and physics, including:

• What is the role of water in molecular recognition and activity?
• How do we achieve shape controlled protein assembly by design?
• How do nature’s flavoproteins transduce light into action?
• How do quantum effects influence biological function?
• Can we generate, measure and utilize spin entanglement?

To answer these, we rely on the oldest tools available to humanity, the power of observation and the ability to draw unbiased conclusions. However, to reveal new insights, our observational lenses must become brighter, sharper, and more versatile. The Han Lab believes the next-generation lenses will harness quantum effects and spin-based qubits, offering atomic-resolution information about molecular surfaces in water, as well as chemistry, structure, and dynamics. While there is widespread excitement about spins as quantum sensors, we see a critical knowledge gap that we are positioned to bridge. By integrating novel magnetic resonance concepts with quantum sensing and optical spectroscopy, we aim to develop next-generation quantum spectroscopy and microscopy capable of transforming our understanding of life-science chemistry and physics. With unique instrumentation, we seek to resolve long-standing questions about the active role of spin quantum effects in biology and chemistry.

Our Values

The Han Lab—home to the SpinQube (Spin Quantum Bit Explorer) Space—believes that truly groundbreaking discovery requires both novel tools and unconventional thinking. We develop innovative quantum sensing, magnetic resonance, and spectroscopic methods to observe phenomena from entirely new angles, revealing what remains unknown until measured. Breakthroughs emerge not from simply working harder on established paths, but from exploring uncharted territory with curiosity-driven approaches that embrace risk and the willingness to “lose” in pursuit of big wins.

Equally central to our philosophy is cultivating confident, independent leaders. Our primary product is not merely high-impact papers—those follow naturally—but talented scientists who think critically, innovate boldly, and lead with clarity. We invest deeply in building this confidence, fostering an environment where people thrive over the long haul.

We are humans before scientists. Mutual respect, trust, open communication, and strong relationships form the foundation of everything we do—from daily work and collaborations to resolving challenges and meeting goals. Every lab member deserves respect regardless of background or experience; there are no dumb questions and no hierarchy of inherent superiority. A great scientist is defined not by prior knowledge or technical skill alone, but by a mindset of unbiased observation, intellectual courage to challenge convention, and commitment to truth even when inconvenient.

As scientists, we pursue rigorous, transparent, and objective inquiry, prioritizing clear communication that advances knowledge broadly. Our publications and shared tools are designed for accessibility, reproducibility, and impact beyond our lab—fame is secondary to enabling discovery across the community. Through empirical evidence and responsible science, we aim to uncover fundamental truths and enrich understanding of the natural world.
