Molecules. Qubits. Markets. One method, three fields.

一套方法,三个领域。

Each room runs the same loop: collect the data, model the system, predict the next state, refine when the world surprises you. Whether the system is a binding affinity, an industry's trajectory, or a security's distribution, the craft is one — forecasting that earns its claim by paying its dues to data.

Xiaohan Zhang张霄汉

Bioanalytical and materials chemist, postdoctoral fellow in the Juewen Liu group, Department of Chemistry, University of Waterloo. The work discovers DNA aptamers by SELEX and turns them into label-free biosensors and aptamer-functionalized nanomaterials; four free analysis tools and the AptaPilot pipeline grew out of it. Ph.D., Shandong University; M.Sc., University of Aberdeen; B.Sc., Shandong Normal University and University of Waterloo (2+2). Founder of RBTX Technology, a quantum and AI industry research firm in Jinan, and Psi, a quantitative technology firm in Toronto.

张霄汉,生物分析与材料化学研究者,现为加拿大滑铁卢大学化学系博士后,在刘珏文(Juewen Liu)教授课题组工作。研究以 SELEX 筛选 DNA 适配体为主线,将其转化为无标记生物传感器与适配体功能化纳米材料,并由此开发了四款免费分析工具与 AptaPilot 流程平台。山东大学博士,阿伯丁大学硕士,本科为山东师范大学—滑铁卢大学 2+2 项目。同时创办睿铂腾霄科技(RBTX,济南,量子与人工智能产业研究)与 Psi(多伦多,量化技术)。
