About my research

Feel free to call me by my first name, Mahei. It is pronounced "Ma-Hi". I am a researcher, who is studying Service Systems and Service Graphs in particular. My research focus is rooted in my phenomenon-driven interests, design research, and formal modeling experience of digital services and service systems. I am currently researching how to design AI-based services to augment IT service management employees at an operational level and how to leverage synthetic data generation for privacy-safeguarding data sharing ecosystems. Within my research, my co-authors and I have observed how employees use intelligent systems and tools to change the way they work. My aim is to conduct industry-driven research that leads to fundamental scientific contributions.

About my research on Service Graphs

One of my passion lies in finding novel ways to expand and apply directed hypergraph theory to create service models that integrate both resource structures and process structures.

Imagine you want to build a car. First, you need to know what parts make up a car, commonly referred to as a bill-of-material or product structure. That's your resource structure. Once you know what parts you require for a car, you need to find out in which sequence they need to be stuck together. That's your process structure. Let's make things a bit easier and assume there is only one way to create your car, so there are no variants and all our parts for the car are in your inventory. Once we have everything in order, you can start planning how to produce your car. You just need to schedule the resources required to stick your car parts together! We won't go into the details, but did you notice the constant switch between your product and process structure? That's because these two structures are essential. Now imagine what you can do, if you have a theoretical (formal) model that allows having both information in one structure!

Let's go even further and imagine what you can do if are not talking about producing a car, but a service, a digital service, or a combination of all three things put together! Things get messy and seemingly complex. That's where Service Dominant Logic (SDL) kicks in and provides us a conceptual foundation to draw these different ways of creating value together. With the Service Graph, we are able to model the concepts that have been proposed in SDL and provide service systems of the future a theoretically sound and mathematically concise model!
