Degree

PhD Michigan State University (2009)

Professional Experience

Associate Professor, 2016-Present, Departments of Biology and Mathematics, Colgate University

Assistant Professor, 2010-2016, Departments of Biology and Mathematics, Colgate University

Research Associate, 2009-2010, Department of Biochemistry & Molecular Biology, Michigan State University

Teaching Assistant, 2002-2009, Department of Mathematics, Michigan State University

Specialties

Systems Biology, Mathematical Biology, Bioinformatics, Biological Regulatory Networks, Zebrafish Segmentation and cis-Regulation in Transcription.

Teaching/Research Interests

My teaching interests include Systems Biology, Bioinformatics, Modeling of Biological Systems, Biostatistics, Numerical Analysis, Differential Equations, Linear Algebra and Calculus.

My main scientific interests lie in applying mathematical modeling to understand biological regulatory networks. Specifically, understanding the design principles of biological gene regulatory networks, mechanisms that control zebrafish segmentation during development and cis-regulation in transcription.
