Some time ago, I wrote a handbook article on epistemic contextualism for Martin Grajner and Guido Melchior's Handbuch Erkenntnistheorie, published by J.B. Metzler. I am happy to report that the book is now available, here or here. The article is in German. Look here for a draft and here for the final version.
I am very happy to report that my first paper on logical pluralism is forthcoming in a special issue on logical pluralism and normativiy in Inquiry. An online first version of the paper is here. Please don't hesitate to contact me, if you cannot access the journal–––I still have some free copies to give away.
