Lars Rohwedder, Ph.D.

About me

I work as a postdoctoral researcher in theoretical computer science. I am excited to be part of Ola Svensson’s group at EPFL, Lausanne (Switzerland). Before that I have received my Ph.D. in computer science at CAU, Kiel (Germany) where I was adviced by Klaus Jansen. I am alumni of the Studienstiftung des deutschen Volkes (German Academic Scholarship Foundation). Recently I have served in the program committee of WAOA’20.

In my personal life, I’m married and I have two dogs and two cats. Some of my hobbies can be seen in the gallery below.

You can find my CV here.
Wedding

My wife Faiza and I have married in fall 2019.

Beer brewing

One of my hobbies is to brew my own beer.

Winter sports

I'm a big fan of winter sports, in particular, of snowboarding.

The dogs

Doing dog things on Gornergrat.

Research Interests

My research focuses on algorithms in theoretical computer science. I am interested in combinatorial optimization, approximative and parameterized algorithms. Most of my work is connected to scheduling and (integer) linear programming.
