For prospective Graduate Students (MSc and PhD):

Much of my research focuses on firm decisions, e.g. retail pricing decisions, firms collaborating with each other for innovation, technology adoption (digital transformation of business), designing salesforce and franchise systems, managing conflict in dealer networks, organizing omnichannel marketing etc. I also study how customer (firm/individual) limits to information processing abilities impact business decisions. Understanding how these business practices can impact sustainable development and climate stewardship are important considerations and offer interesting, valuable, as well as challenging research opportunities. I aim to do theoretically driven quantitative empirical work and students working with me get trained accordingly. 

If you are interested in pursuing graduate studies in the areas of my interest and want to learn together with me, please do feel free to reach out to me with your cv. If there is a fit, I will respond and explore further. A background in technology and industry experience are desired but not necessary. Discipline, initiative, curiosity, perseverence and comfort in navigating uncertainty are all necessary for ensuring success. Graduate studies is exciting and challenging and I wish you all the best in your efforts to find a fit.

Please contact the graduate school for details about programs, elgibility, deadlines and regulations. Do note, all admission and scholarships are committee decisons.
