  • 经历

    Plunify

     

    2011. 5 – 2011. 9

    曾经在Plunify做软件工程师假期实习生。Plunify是一个位于新加坡的创业公司,提供给芯片设计者SaaS云计算服务。实习期间,我主要负责Java的后台编程工作。与一个5人团队一起,打造公司早期的脚本系统。现在Plunify的产品正在为来自30多个不同国家的200多家机构服务。

    Coordinated Science Lab

    2012. 8 – present

    在Coordinated Science Lab (CSL),我和我的老板 Yoram Bresler 一起从事稀疏表达,机器学习方面的研究。我们开发了一套新的最优稀疏化变换(Sparsifying Transform)的学习框架和算法,并且在图像处理,大数据处理以及计算机视觉等一些应用方面取得了优异的表现。 我们的专利和软件包(Matlab和C的版本)都在准备之中。目前我们也在进一步开发基于Kernel Machine的学习体系的改良。

    ECE Department

     

    2012. 8 – 2014.5

    我曾担任ECE 210虚拟信号处理课程的首席助教。期间为UIUC的本科生每周开设实验课,和课后讨论答疑课。我的职责还包括管理其他的助教,分配作业批改工作,帮助设计考试题目,实验设计等等。在助教期间,我被学生和老师提名Harold L. Olesen Award以肯定了我的教学工作。
