Prospective Students

I am currently seeking energetic and hard-working PhD, and M.Sc. students. Please send me your CV, transcripts, published/submitted papers, and a sample code if you are interested. I will reply if there is any possibility for collaboration.

To join my research group, you need to know C plus plus programming. It is OK if you are proficient in another programming language, but you definitely need to learn C plus plus  before starting your research. In this case, I strongly recommend this series of videos to learn C plus plus. Experience in calling cplex in C plus plus in a big plus.

Please note that I will reply to the selected applicants. You will not receive a refusal email if I am not interested.
