I am Jiahao Zhang (张家豪), a first-year PhD student in the Machine Learning Department at MBZUAI.

Research Interest. I study Explainable AI (XAI) as an interactive toolkit to understand and steer model behavior, and to build human-actionable interfaces for reasoning and control.

I use AI for Science as a rigorous stress test: scientific problems provide external, verifiable constraints (simulation/experiments), enabling a closed loop of explain -> intervene -> validate, so XAI improves not only interpretability but also reliability and real-world effectiveness.

Controlling Repetition in Protein Language Models cover Click cover to view abstract
Protein language models (PLMs) frequently collapse into pathological repetition during generation, which undermines structural confidence and functional viability. We present a systematic study of repetition in PLMs and propose Utility-Controlled Contrastive Steering (UCCS), which steers generation using contrastive sets that maximize repetition differences while controlling structural utility. Across ESM-3 and ProtGPT2 on CATH, UniRef50, and SCOP, UCCS reduces repetition without retraining while preserving foldability-related confidence.

Solar-driven evapofiltration enables co-production of lithium and freshwater from extreme brines cover Click cover to view abstract
Brines are an important lithium resource, but their utilization remains limited by poor lithium selectivity in highly saline, magnesium-rich environments and by freshwater scarcity in the arid regions where many such resources occur. Here we report evapofiltration, a separation strategy for simultaneous production of freshwater and lithium from extreme brines. The strategy is realized using an evapofiltration membrane that integrates a commercial nanofiltration membrane with a carbon-nanotube photothermal layer in a recirculating NF evaporator. In Dead Sea brine composition, the system driven by solar sustained freshwater production at 1.24 kg/m^2/h while achieving 320-fold lithium enrichment over four stages, ultimately yielding battery-grade Li2CO3 with 99.58% purity. An experimentally informed artificial-intelligence framework further integrates brine chemistry and local solar conditions to predict site-specific lithium and freshwater production from diverse brine resources worldwide. Evapofiltration therefore provides a promising route for integrated lithium recovery and freshwater generation from extreme brines in water-scarce regions.
