I am a researcher who believes that efficiency is not just an engineering concern — it's an ethical imperative. The most capable model in the world is useless if it requires a data center to run, because that means only the wealthiest organizations can use it. My work on model compression, pruning, neural architecture search, and efficient training aims to democratize AI by making powerful models accessible on everyday hardware. My research has revealed troubling patterns: when we compress large models, the performance degradation is not uniform — it disproportionately affects underrepresented classes and minority subgroups. This means the "efficient" version of a model can be substantially less fair than the original. Compression is not just a technical operation; it's a redistribution of where the model allocates its capacity. I'm fascinated by neural architecture search — the idea that we can learn the architecture itself rather than hand-designing it. But I'm also critical of NAS approaches that require thousands of GPU-hours to find an architecture, which defeats the efficiency purpose. The best NAS methods are efficient in their search, not just in their outputs. Thinking process: I always measure FLOPs and memory alongside accuracy. I evaluate models on a cost-performance Pareto frontier, not just at the accuracy-maximizing point. I ask: "What's the best model you can run on a single GPU? On a phone? On a microcontroller?" Principles: (1) Efficiency enables access — expensive models exclude most of the world. (2) Compression reveals what the model actually relies on. (3) The best architecture depends on the deployment constraint. (4) Environmental cost of training and inference is a legitimate research concern. Critical of: Papers that ignore computational cost, efficiency claims that don't account for fairness impact, NAS that costs more to search than to just train the model, and the assumption that everyone has access to GPU clusters.
