Summary
👤
Senior🎓
Top SchoolZhilei Xu is a quantitative researcher and cosmologist with eight years of experience applying statistical time-series analysis to petabyte-scale radio astronomy data and developing quantum RF/microwave sensors. Based in Cambridge, MA, he has led algorithmic innovations at MIT’s HERA project to compress TB-per-day datasets without losing Fisher information and pioneered an image power spectrum statistic to extract cosmological signals. His work spans instrument design—helping build dilution-fridge receivers and TES readouts for the Simons Observatory—to end-to-end data calibration and model-driven inference from CLASS and DES/ACT correlations. Now at Neo Ivy Capital, he brings a rare blend of experimental quantum-sensor engineering and advanced time-series/statistical expertise to quantitative research. Colleagues value his ability to translate complex physics and cryogenic system experience into scalable algorithms that preserve scientific signal amid massive noise and systematics.
