ICCB J-7

I’m heading to ICCB very soon. I am looking forward to seeing motivating presentations and exchanging ideas.

CPSN

Does influence matters?

I will present my current work on organizing social networks to achieve best biodiversity outcome (Monday 21st). I’m also involved in a project with Jonathan Rhodes in which we try to assess the importance of influence in networks. More on our symposium here.

Feel free to send me an email if you want to chat, I will have some time in between sessions!

After ICCB I’m heading to Europe and France. I will work with my colleagues from INRIA – Olivier, in particular. I can’t wait to challenge him with some complex problems we have no solutions for!

In the meantime Sam will present our last piece of work at IJCAI (Beijing).

Good news

I had good news yesterday.

1) I received a Julius Career Award to help me doing my research on adaptive management over the next 3 years and in particular a 6-month sabbatical.

2) We made substantial progress on our research project where we are trying to find the best social network for a given ecological network. We spent the day brainstorming and programming with Sam Nicol, Shaun Coutts and Angela. Jesse Hoey has been very helpful too and kindly updated SPUDD for the purpose of this study. I feel that this project has the potential to be a kick-ass paper. It feels great to do some cool fresh science!

3) I’m also the new Team Leader of our Conservation Decisions team. I hope I can keep managing my time efficiently so that I can produce good science and mentoring to the team.

I’m off to ICCB in 15 days (Baltimore) and then France for more adaptive management research!

 

A busy month ahead

I’m trying to start and finish a project in the next month. The project involves a lot of thinking and programming. I’m trying to solve a large action space Factored MDP. It’s challenging because the actions can’t be factored. It’s almost a flat MDP.
I’m hoping that the results will be easily interpretable. There is no point finding an optimal solution if I can’t explain it :-)
I’ll try to report the progress I make as we go.

Expert elicitation and priority threat management in the Pilbara

This year, our team has been working on a cost benefit analysis project to determine the priority threat management options to protect the listed species of the Pilbara, WA.

Part of our project consists in gathering data from different sources, published and grey literature, and most importantly experts knowledge. We ran an anonymous expert elicitation workshop in March 2013 to gather the critical information needed for our project.

When running an expert elicitation exercise it is recommended that experts remain anonymous so that bias is limited when collecting the expert knowledge (benefit estimates, in this case). Once the preliminary analysis is done and individual mistakes are corrected, it is important to provide a way of discussing the results as a group so that additional information can be exchanged and informed discussion can lead to less divergence in opinions.

To set up that discussion phase and maintain an anonymous process, we have set up a forum for our experts to comment and discuss the current group trends and divergence. We’ve had a couple of responses to our forum from contributors who said that they’d appreciate more information about how to use the forum. In response I recorded a quick video that captures my screen as I go through the features of the forum. The video is available on YouTube, and can be accessed at the link below. You can play this video full screen and you can also increase the quality to High Definition (HD).

 

Complex decisions made simple

We recently had a paper accepted in Methods in Ecology and Evolution. I can’t say too much about it yet, but I hope it will be well received and useful to many. Well done Lucile and team!
