INTRODUCTION
I am originally from Germany and came for a oneyear student exchange. Life intervened and I decided to stay and do a Ph.D. at USC (University of Southern California in Los Angeles). I graduated in 1992 and then had two oneyear visiting appointments, at Colorado College in Colorado Springs and at Humboldt State University in Arcata. I came to Cal State LA in the Fall of 1994 and have been here ever since. In my free time I like to read, watch foreign and independent movies, hike, camp, dance and stand on my head on a daily basis.
TEACHING INTERESTS
I teach courses ranging from general education to graduate level courses, mostly statistics, probability, modeling and the Mathematica course. I use Mathematica in most of my courses to visualize concepts and algorithms. My most recent focus has been the redesign and teaching of the new mathematics sequence for life sciences majors, Math 1050/1085, Math 2040/41, and Math 2050/51. These courses were developed with an NIH grant that had the goal to strengthen the quantitative skills of life sciences majors. In these courses, mathematics is taught in the context of life science and biological applications, and the course topics are those that life science makors will see in the applicaitons in their major courses. Another aspect of the grant was the introducation of a minor in bioinformatics. I have contributed two chapters on probability and its applications in bioinformatics to a textbook used at Cal State LA, Concepts in Bioinformatics and Genomics, authored by Cal State LA faculty Drs. Momand and McCurdy, with additional contirbutions by Dr. WarterPerez.
GRANTS AND INITIATIVES
 I am the faculty learning community coordinator on the First In The World grant on flipped learning. More details about the grant can be found here. This grant provides funding for faculty from STEM disciplines to try out flipped teaching in bottleneck courses.
 I am one of the leads for the course redesign of General Education courses in response to EO 1110. Information about the changes can be found at the math department advisement webpage.

RESEARCH
My research spans a number of areas, ranging from operations research to modeling to combinatorics. My Masters thesis investigated a stochastic model for inventory control (Operations Research), while in my Ph.D. thesis, I developed a stochastic model for the movement of a white blood cell. With Raj Pamula, I have worked on a model of a system of parallel processes to compare different methods of error recovery. Work on (enumerative) combinatorics, in particular questions related to tilings and compositions with a number of collaborators has culminated in a book entitled Combinatorics of Compositions and Words, which is a resource for research in this area. Most recently, I am working on questions related to combinatorial games, an area that lends itself to student research. If you want to find out more about Combinatorial Game Theory, check out Kyle Burke's blog or the website on combinatorial games.
