Mohammad Hajarian is a Marie Curie Postdoctoral Fellow and an Assistant professor at the University Carlos III of Madrid. He is a PI of an EU-funded project about developing engaging methods for regulating user behaviors in social media to prevent problems such as fake news, misinformation, online hostility, misogyny, and misunderstanding that can harm human mental and physical health. His research fields are Online Social Networks, Gamification, Human-computer Interaction, Interaction design, Recommendation Systems, Personalization, User Engagement, Data Science, and Online Marketing. He is also the programmer, designer, founder, and director of the Gegli social network since 2003 (Formerly known as Gohardasht.com), and he uses his social network to implement and investigate most of his algorithms and frameworks in a real environment. He also collaborates with other researchers to investigate their methods in a real social network environment. During his professional career, he participated in several software projects, conferences, and workshops and worked as a reviewer in several prestigious journals and conferences. Furthermore, he taught 35+ computer courses in several universities and supervised 10+ theses at the graduate and postgraduate levels. He published 50+ articles and books in computer science and software engineering. And his innovative contributions have been exploited in the social media industry.

ROSNUB (Project ID: 2018/00578/037) is a Marie Sklodowska-Curie Actions (MSCA) COFUND CONEX-Plus Project ( PI: Mohammad Hajarian). Reputation Metrics and Methods for Gamifying and Regulating Online Social Network Users’ Behaviors (ROSNUB) Project aim to address the problems online social media can cause in today’s human life. Nowadays, in online social networks, users are exposed to fake news, misinformation, online hostility, and misogyny talks generated by other users. In this situation, users might have less regulated emotions, accept extreme behaviors, and misperceive each other. These problems can start from social media and affect people’s mental and physical health in real life. Study results show that more than half of young social network users have experienced cyber aggression resulting in emotions such as depression, suicide, and embarrassment in their life. Incel movement is an excellent example of transforming hostility from online social networks to the real world. To tackle the mentioned problems, social media users’ behavior should be regulated. While legal solutions might help, they are not encouraging, and current social media ecosystems have been built on a foundation that encourages users to engage in such activities to gain more attention or, in other words, likes. Although a good number of studies have been conducted on these mentioned problems in social networks, all are about detecting such problems, and software engineering approaches for preventing them have not been investigated. This is very important because prevention is always a better solution than detection. As a result, this project investigates algorithms and frameworks to regulate social network users’ behavior joyfully in a personalized way and from the software engineering perspective to increase citizens’ mental and physical health and wellbeing.

A research-based Social Network. Gegli, formerly known as Gohardasht.com, is among the world's first social networks. It has been my lifelong project since 2003. It has around half a million members, and new users join daily. Includes communities, blogging services, groups, chat rooms, p2p chat, and many other features. This website and mobile application contain millions of lines of code that I wrote in ASP, JavaScript, SQL, and other programming languages and frameworks. URL: Gegli.com
