Employment

April 2010 – present  —  Associate Professor, Mathematics, Spelman College, Atlanta GA, USA

Fall 2007                       —  Visiting assistant professor at University of Florida.

2004 – 2010                — Assistant Professor, Mathematics, Spelman College, Atlanta GA, USA

2000 – 2004               — Teaching Assistant, Temple University, Philadelphia PA, USA

 

Education

• PhD  in Mathematics (2004) — Temple University, Philadelphia, USA.

Teaching

I have taught a wide range of courses at Spelman from introductory level college algebra, precalculus & calculus sequences to upper level theory courses such as abstract algebra, real variables, complex variables and topology.  

 

Research

My area of research is in algebra, more specifically invariant theory and computational commutative algebra. I am also interested in ordered algebraic structures such as lattice ordered groups and Riesz spaces.

Research Experience with Undergraduates.

•  I am actively engaged in mentoring students on several independent study and research projects. So far I have supervised more than 18 students.
•  In collaboration with math faculty from Clemson University we were awarded a two year NSF grant to conduct Summer REU for 2012 and 2013.
•  Served as a judge at several Math and Engineering fairs in Georgia including;  The Intel International Science and Engineering Fair, and the Georgia Science and Engineering Fair.
