I joined the CPLEX team in 1991 and have been involved in CPLEX development, training and documentation and support. I have leveraged my experience supporting CPLEX users to provide numerous conference presentations, workshops and web seminars on the effective use of CPLEX. Combining that with my extensive experience in all technical aspects of mathematical programming software has enabled me to communicate the customer experience with the developers and explain technically challenging aspects of the software to its users. This is reflected in the 3 publications (all in refereed journals) that I have written since joining IBM in 2009. I obtained a PhD in Operations Research from Stanford University in 1988.
Regarding research interests, while I am interested in all aspects of mathematical programming, my primary interests involve those that can have an impact on mathematical programming software such as CPLEX.
