While he doesn't specifically mention any project, since V13 (Fallout Online) is the only project currently in development at Interplay, it can be assumed that it's the game he's working on (especially that some of his work is post-apocalyptic).
From his LinkedIn page:
I have been working as a concept artist at various game companies in southern California for the past four years. After graduating from Laguna College of Art and Design I interned at Highmoon Studios and was promoted to a storyboard artist within a few months by Farzad Varahramyan. I spent my time working on the Bourne Game and started a figure drawing work shop for all the artist there. I later went to work for Obsidian Entertainment where I was the lead environment artist on Alpha Protocol. I also brought my passion for figure drawing there, and started a drawing class for Obsidian.
I'm currently working at interplay as the lead concept artist.

There's some nice post-apocalyptic art in his gallery already, although it is unknown whether any of it is directly related to Fallout Online.
