Background and activities

My research interests include numerical optimization algorithm, systems and control, embedded systems design, and software development. I am interested in applying efficient numerical methods for systems and control applications. I am now a postdoctoral researcher at Process Control group under the supervisor Associate Prof. Johannes Jäschke.

I obtained my PhD degree from Department of Engineering Cybernetics - NTNU in 2012. My PhD project was on gradient-based optimization methods for large-scale system (see publication below). I got my master and bachelor degrees from Departement of Electrical Engineering at Bandung Institute of Technology in 2002 and 2004, respectively. In between my academia years, I worked as IT consultant for SAP projects and embedded software developer for subsea control systems (mostly developing data communication protocol stacks of subsea sensors).  

In my spare time, I enjoy doing volunteer activities and contemplative practices. Also, I like to do DIY-projects.
