Sanne is Associate Professor at the Department and is located in building 2628(M), office 319.

How long have you been employed at the Department of Economics and Business?
Since the Department was formed in the summer 2011. Before that, I was employed at the former Department of Business Studies at Aarhus School of Business - since 2005.

What is your background?
I studied mathematical economics at University of Southern Denmark and specialized in a combination of Operations Research and Theoretical Computer Science (algorithmics). I earned my PhD from the same university. After that, I got a position as assistant professor at the former ASB. 

What are your main areas of research?
I have two areas of interest which are partly overlapping. The first is on the so-called arc routing problem, which is a transportation problem where street segments need some kind of service. This problem occurs e.g. in snow removal, refuse collection, and winter gritting. This has been my key topic since my master thesis. The second is the transportation problems arising in collection of waste and recyclable materials. For both areas, my research focus is on the development of solution procedures. So that is a lot of math and theory followed by programming in order to test the procedures.

What research projects are you working on at the moment?
I am working on a great project with Reno Djurs where we study the collection of household waste and try to determine the transportation cost of different scenarios of separating waste to different degrees. I have a number of master thesis projects involved in this work and we all really enjoy it.

What are you involved in teaching-wise at the moment?
I teach programming to about 200 cand.merc. students. It's a tough course to get through for the students, but most of them appreciate it once they graduate and realize how useful it is in the real world. I also teach part of a course about transportation models. 

Are you planning to take part in any conferences or the like abroad in the near future?
I am head of the organizing committee of a workshop focusing on arc routing, which is hosted by our department in the spring. Besides that, I plan to participate in the EURO-INFORMS conference in Rome this summer.

Are you expecting any visiting researchers from abroad in the near future (or have you had any visitors from abroad recently)?
We just had Bernard Gendron, who is director of the CIRRELT research centre in Montreal, visiting for a week. Part of the purpose of his visit was to form a partnership between CIRRELT and CORAL. 

Are you cooperating with researchers from other departments at AU at the moment?
No. Though I have an agreement about a future project with one from NERI.

What do you do when you are not at work?
My family could claim that there is no "not at work", but I try to squeeze in a bit of time for my husband, four children, a countryside property, and two horses.
