In Winter 2016 I am teaching Real Analysis 2, and two sections of Calculus 2 (MATH 1952). In Spring 2016 I am teaching two sections of MATH 1150 - Perspectives in Art. In Winter 2016, I taught Real Analysis 2, and two sections of Calculus 2 (MATH 1952). During Fall 2015 I was a Fellow at the Isaac Newton Institute, Cambridge, UK, for the Programme on Mathematical, Foundational and Computational Aspects of the Higher Infinite. In Fall 2014 I taught undegraduate Set Theory (MATH 3050) and Calculus 1 (MATH 1951). In Winter 2015 I bought a course release from funds from my NSF grant. In Spring 2015 I taught graduate Combinatorial Set Theory (MATH 4050) and Perspectives in Art (MATH 1150).
Dan Hathaway and I will be organizing a special session on Set Theory at the AMS Sectional Meeting to be held at the Unviersity of Denver in October 2016.
The DU Sesquicentennial Ramsey Theory Conference 2014 was held at the University of Denver, May 24 - 28, 2014. The meeting was organized by Jose Mijares and myself. We thank the National Science Foundation and The DU Provost Sesquicentennial Fund for funding to support many participants.
DU is the birthplace of the BLAST Conference Series. The last BLAST was held at University of North Texas in June 8 - 12, 2015 BLAST North Texas. Winter BLAST 2015 was held at New Mexico State Univerisity, Las Cruces. BLAST 2013 was held at Chapman University. BLAST 2011 was at the University of Kansas; BLAST 2010 was held in Boulder; BLAST 09 was held in Las Cruces. BLAST 08 was held in Denver. Co-chairs were Professor Nikolaos Galatos and myself. BLAST 08. BLAST stands for Boolean algebras, Logic, Lattices, algebraic Logic, universal Algebra, Set theory, Set-theoretic Topology, point free Topology, and general Topology. These are logic-related areas of interest to researchers at Chapman University; New Mexico State University, Las Cruces; University of Colorado, Boulder; University of Denver; University of Kansas, Lawrence; University of Missouri, Kansas City; University of Nebraska, Omaha; and University of North Texas. The BLAST series is graduate-student friendly and supports participation of graduate students, post-docs, and young researchers with NSF funded travel and lodging support.
MIG. The series of Maximally Informal Gatherings is a consortium of logicians from the Boulder, Denver, Fort Collins areas. We gather on selected Saturdays to share research talks, ideas, and lunch.
I have also organized various special sessions and served on program committees for conferences of the ASL and the AMS. These are listed in my CV.
From 2008 until May 2014, I was the coordinator and supervisor for the Graduate Colloquium which meets on Fridays at 2pm. See Graduate Colloquium for a list of past and present speakers.
Advising and mentoring.
I was PhD advisor to Timothy Trujillo who earned his PhD in Spring 2014, with thesis: Topological Ramsey spaces, associated ultrafilters, and their applications to the Tukey theory of ultrafilters and Dedekind cuts of nonstandard arithmetic. Dissertation_Trujillo_2014
From Fall 2013 - Spring 2015 I have been a mentor to postdoctoral scholar Jose Mijares. In 2015 I co-advised (with David Meza-Alcantara) Sonia Navarro Flores on her masters thesis at UNAM Morelia, Mexico. From Fall 2015 onward, I am mentor to DU postdoctoral scholar Daniel Hathaway.
