Welcome to my page. LD 270C Department of Mathematics IUPUI 402 Blackford St Indianapolis, IN 46202 (317) 274-6940 buse@math.iupui.edu				I am an Assistant Professor at IUPUI. Before coming here I was a Postdoctoral Associate at Michigan State University. In the Spring of 2010 I was a research member at the Mathematical Sciences Research Institute in Berkeley, CA. My research interests include: Symplectic and Contact Geometry, four-manifolds, singularities, Complex and Algebraic Geometry, Mathematical Biology. Curriculum Vitæ. Research: Quantitative Symplectic and Contact Geometry "Symplectic embeddings of ellipsoids in dimension greater than four", O. Buse, R. Hind. Geom. Topol., 15, 4 (2011), 2091–2110. "Packing numbers of rational ruled 4-manifolds", O. Buse, M. Pinsonnault. To appear: J. of Sympl. Geom.. "Packing in contact context", O. Buse, D. Gay. Work in progress. "Ellipsoid embeddings and symplectic packing stability", O. Buse, R. Hind. Submitted. Gromov-Witten Invariants and Symplectomorphisms "Negative inflation and stability in symplectomorphism groups of ruled surfaces", O. Buse. J. Sympl. Geom., 9, 2 (2011), 1–14. "Deformations of Whitehead products, symplectomorphism groups, and Gromov–Witten invariants", O. Buse. Int. Math. Res. Not., 2010, 17 (2010). "Relative family Gromov–Witten invariants and symplectomorphisms", O. Buse. Pac. J. Math., 218, No. 2 (2005), 315–341. PhD Thesis. Stony Brook, 2002. Advisor: Dusa McDuff. Mathematical Biology "Existence of limit cycles in the repressilator equations", O. Buse, A. Kuznetsov, R. Perez. Int. J. Bif. Chaos, 19, 12 (2009), 4097–4106. "Dynamical properties of the repressilator model", O. Buse, R. Perez, A. Kuznetsov. Phys. Rev. E, 81, 066206 (2010). Teaching: Math 17100 (Multidimensional Mathematics). Math 57100 (Elementary Topology). Since Fall 2010 I have been course coordinator for the Calculus sequence (Math 16500/16600). Miscellaneous: From Spring 2008 to Fall 2009, I co-organized a cycle of four Illinois-Indiana Symplectic Geometry Conferences.
