Jun.-Prof. Dr. Tetyana Kosyakova
Junior Professor of Marketing Management at HHL Leipzig Graduate School of Management
I am a Junior Professor of Marketing Management at HHL Leipzig Graduate School of Management. I obtained my PhD degree at Goethe University Frankfurt.
In my research, I develop and apply advanced quantitative methods to study consumer decision-making processes, model consumer choice, and elicit consumer preferences to support the innovation process and help businesses optimize their offerings. I use Bayesian techniques to uncover consumer heterogeneity and understand differences in preferences and responses to marketing activities. I am also deeply interested in the potential of high-dimensional unstructured data for marketing research.
Research Interests:
Consumer Choice, Choice/Marketing Modeling, Bayesian Methods and Applications in Marketing, Models of Consumer Heterogeneity, Demand Estimation, Menu-Based Choice and Product Configurators, Targeting, Customer Base Analysis, Unstructured Data.
