News:

• My daughter, Autumn Mary Baldridge, was born in July.  She is cute, happy, healthy, and already in control of my life.  See pictures here and here.
   
• Elementary Geometry for Teachers, a book I co-wrote with Thomas Parker of MSU, was published August 2008.  It is available at Singaporemath.com.  You can find instructor resources (as well as instructor resources for my other textbook, Elementary Mathematics for Teachers) at:

• The Baker School Project is off to a great start.  Teachers and graduate students are working together to implement the Primary Mathematics Curriculum in the City of Baker.  Pictures of the 2-week professional development can be found here.

Recent Notable Achievements:

• I am one of the CAREER award winners for 2008.  This award provides over $450,000 for my mathematical research over the next five years.  This is part of over $1.7 million in funding I've been awarded for projects in mathematical sciences.
   
• Last year, together with Paul Kirk of IU, I constructed and proved the existence of an exotic 4-manifold homeomorphic but not diffeomorphic to CP^2#3CP^2b (see preprints).  The paper was published in the journal Geometry & Topology, and recently another paper on this research was recommended for publishing in the Journal of the European Mathematical Society (JEMS).
   
• Elementary Mathematics for Teachers and Elementary Geometry for Teachers were rated highest among college math textbooks for teachers in their respective categories in a recent report by the National Council on Teacher Quality.
