OmniMap: A General Mapping Framework Integrating Optics, Geometry, and Semantics
Robotic systems demand accurate and comprehensive 3D environment perception, requiring simultaneous capture of photo-realistic appearance (optical), precise layout shape (geometric), and open-vocabulary scene understanding (semantic). Existing methods typically achieve only partial fulfillment of these requirements while exhibiting optical blurring, geometric irregularities, and semantic ambiguities. To address these challenges, we propose OmniMap. Overall, OmniMap represents the first online m…

Unpaving paradise: Tahoe tears up motel to restore floodplain
What 30 X 30 looks like in action. State agency demolishes a motel and restaurant to bring water and life back to a meadow. (Photos best viewed on a desktop).

The Elephants Remember: On Activism, Memory, and Holding the World Steady
Not all activism is about pushing forward. Sometimes it’s about remembering, holding, and steadying what’s worth saving. A reflection on emergence, tenderness, and what the elephants can teach us about endurance.

I find there is a lot of overlap between the following groups:
- people who are mission-driven and want to fight for a better future
- people who hate negotiation and think it makes them "selfish"
If you fall into those groups, please check out my negotiation tutorial. It is written specifically for YOU. 💖

How to Negotiate Without Being Pushy: The Empathy-Based Approach That Actually Works
Negotiation doesn’t have to be a battle of wills. Learn how to reach agreements through empathy, clarity, and mutual respect — even if you hate confrontation. This step-by-step guide shows you how to stay calm, connected, and confident in any negotiation.

Radio-Frequency Detection of Fabry-Pérot Interference and Quantum Capacitance in Long-Channel Three-Dimensional Dirac Semimetal Cd3As2 Nanowires
We demonstrate phase-coherent transport in suspended long-channel Cd3As2 nanowire devices using both direct current (DC) transport and radio-frequency (RF) reflectometry measurements. By integrating Cd3As2 nanowires with on-chip superconducting LC resonators, we achieve sensitive detection of both resistance and quantum capacitance variations. In a long-channel device (L ~ 1.8 μm), clear Fabry-Pérot (FP) interference patterns are observed in both DC and RF measurements, provide strong evidenc…

The Gift of Contradiction
How embracing our messy tensions can widen movements and deepen integrity. You can care deeply about climate and still live with contradiction. Perfection isn’t integrity. What matters is the direction of your compass.
