of [2]. Comparison of the performance of our multiobjective mesh optimization method with
other mesh quality improvement and mesh untangling methods [3]. Joint work with the authors

Figure 4: Deformed annulus meshes resulting from the use of our Untangling Before
Newton (UBN) method for rotating the exterior
boundary circle of the mesh shown in Fig. 1 by f radians and moving
the inner boundary circle by a factor f closer to the outer boundary.
The deformed meshes are for (left to right) f = 0.1, f = 0.3, f = 0.6, and
f = 0.7 [4]. Joint work with the authors of [4].

Comparison with existing worst element mesh quality improvement algorithms in the literature on
a convex mesh optimziation problem using a smooth aspect ratio quality metric [5]. Joint
work with the authors of [5].
Figure 6: Mesh morphing pipe example [6]. The morphing is performed in conjunction with shape optimization
of the pipe design. Left to right: (a) pipe design and parameters to be optimized, the (b) initial shape,
and the (c) final shape. Joint work with the authors of [6].
Education Results
In Fall 2011, I added parallel meshing techniques and biomedical
applications to the graduate level meshing techniques course which I
designed and previously taught in Spring 2008 and Spring 2010. Here are
relevant course materials for Fall 2011:
Outreach Results
In Summer 2011, I teamed up with Mr. George Otto (Penn State Visualization Group), Dr. Keefe Manning (Penn
State Department of Biomedical Engineering), and Dr. Amy Freeman (Penn State Pre-First Year and
Multicultural Engineering Programs) to offer a workshop to underrepresented entering college freshmen at
Penn State.
Here is a link to (a slightly modified version of) my outreach
presentation on computational biomedical science. This talk is aimed at
entering college freshmen interested in majoring in engineering.
We have also given several conference and invited seminar presentations on various aspects of this project.
