Research
My research interests lie primarily in the fields of supply chain management and data science spanning decision analytics and mathematical optimization problems.
I work on inventory control under demand and supply uncertainty. These decision problems are ubiquitous in healthcare and humanitarian aid operations. I have also studied various mathematical optimization problems in production and service systems, including scheduling, lot sizing, routing, and pricing.
My research also involves combinatorial optimization approaches in numerous subdomains of data science, including supervised learning and time series analysis. In addition, I have applied some of these techniques to the toxicological evaluation of nanoparticles and interpreting EEG data.
