Hi, I'm Xiao-Xiong Lin.

A
computational neuroscientist who wants to understand and enable others to understand

About

I completed my PhD in Computational Neuroscience in September 2023, and am currently actively looking for postdoctoral positions in computational neuroscience as well as industry opportunities in related fields such as Artificial Intelligence, Machine Learning, and Brain-Computer Interfaces.

Research  Interest

My primary research interest is centered on uncovering the fundamental principles of intelligence in biological organisms. I approach this by formally describing and abstracting the physiological observations then analogizing them with engineered intelligent systems. In other words, I am inspired deeply by physics, control science and machine learning.

Currently I am very interested in taking neuroscience insights into engineering practice.

Throughout my PhD research, I engaged extensively in population level neural data analysis. I leveraged biological principles of sparse connectivity to dissect representational geometry of working memory, and identified disentangled representations within distinct neuronal ensembles. This work, now published in Science Advances, aims to bridge the gap between single-neuron and population-level perspectives in neuroscience.
