I am Assistant Professor of Philosophy and Chair of Philosophy and Humanties at Saddleback College, in Mission Viejo CA. I finished my Ph.D (thesis: "Cartesian Skepticism about the External World") at Cardiff University, under the direction of Christopher Norris. In that thesis, I defend such skepticism against epistemic and semantic objections. Generally speaking, I conclude that philosophical skepticism is true, such that, although we can have justified beliefs about the extenral world, they do not amount to knowledge.
