**BLAST 2018 will be held at the University of Denver, August 6 - 10.
**
Nick Galatos and I are pleased to be organizing the 10-year anniversary of the BLAST conference series, which we commenced in 2008 at the University of Denver.
BLAST 2018 is an interdisciplinary conference focused Boolean algebras, Lattices, Universal algebra, Set theory and Topology, and their interactions. This is a good conference for graduate students, early career mathematicians, and anyone interested in expanding their research to include some neighboring areas.
Funded by the NSF and by the University of Denver, there will be support to help graduate students and early career mathematicians participate.
Details on the BLAST 2018 website.

** Research.**
I work in Set Theory, Ramsey Theory, Topology, and related areas.

** Recently I solved the problem of "big Ramsey degrees for the universal triangle-free graph".** Reviewers' comments for Annals of Mathematics called this "a remarkable achievment", "the first major advance towards the Ramsey theory of Fraisse limits that have forbidden configurations", and wrote that "Many top names in combinatorics worked on this problem for years, so it can be definitely confirmed that the problem is hard and important." The three reviewers' comments are posted here.
As one of the reviewers found "such results in infinite Ramsey Theory less exciting than some in the finite theory," the paper was declined and I have submitted it to another journal.
A pre-preprint is available on my Research Page. Currently I am writing up the result on big Ramsey degrees for all universal k-clique-free graphs.

**Grants and Awards.**

My research is currently supported by National Science Foundation Grant DMS-1600781. "Ramsey Theory, Set Theory, and Tukey Order." September 1, 2016 - August 31, 2019. $129,995.

I won the Excellence in Research Award, University of Denver, Division of Natural Sciences and Mathematics, 2015-2016.

See Grants and Awards for the listing of these and previous grants and awards.**
Teaching.**

In Fall 2017 I taught Calculus 1 (MATH 1951). In Winter 2018 I am teaching two sections of Perspectives in Art (MATH 1150), Logic (MATH 3060), and a Graduate independent study course for several students in infinitary Ramsey Theory. Spring 2018, I am working solely on research.

As of January 1, 2018, I am Chair of the ASL Committee on Logic in North America, and an ASL Council member. Past service includes a 3-year term on the Committee on Logic in North America, and a two-year term on the ASL Web Advisory Committee.

Association for Women in Mathematics.**

The Mathematics Department at DU now has an AWM Student Chapter. The Faculty Sponsor is Professor Mei Yin and I am the Faculty Co-Sponsor.

**
Conference Organizing.**

Nick Galatos and I (Chair) are organizing BLAST 2018. This 10-year anniversary conference will be held at the University of Denver, August 6-10, 2018.

Dan Hathaway and I organized a special session on Set Theory of the Reals (including Ramsey Theory) at the AMS Western Sectional Meeting 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.

Front Range Logic Saturdays (formerly known as the Maximally Informal Gathering or MIG) is a consortium of logicians from the Boulder, Denver, Golden and Fort Collins areas. We gather on selected Saturdays to share research talks, ideas, and lunch. MIG was started in 2009 by Bart Kastermans and myself. FRLS is currently being run by Dan Hathaway and Timothy Trujillo.

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 - Spring 2018, I am mentor to DU postdoctoral scholar Daniel Hathaway. From September 2018 - August 2019 I will be a research mentor to visiting scholar Dr. Kaiyun Wang from the College of Mathematics and Information Science, Shaanxi Normal University.
