Hajo is an organizational psychologist who studies culture and conflict. His work comprises two interrelated research streams on these two topics: In the first stream on culture, he examines how multicultural experiences, cultural differences, and cultural artefacts influence organizationally relevant psychological processes and behaviours (e.g., decision-making, creativity, and identity). In the second stream on conflict, he explores how people, both from the same culture and from different cultures, deal with emotions in negotiations and conflict situations.

His research has been published in Journal of Applied Psychology, Journal of Business Ethics, Journal of Experimental Social Psychology, Journal of Marketing Research, Organizational Behavior and Human Decision Processes, Personality and Social Psychology Bulletin, and Psychological Science. His findings have also been covered in popular press outlets such as ABC News, BBC News, Forbes, Harvard Business Review, Men’s Health, Newsweek, NPR, The Atlantic, The Daily Mail, The Daily Telegraph, The Guardian, and The New York Times, and he has discussed his work on podcasts, radio, and television.

Hajo has taught management classes on topics such as culture, decision-making, and negotiation to both undergraduate and graduate business students. He has also delivered lectures on negotiation in both company-specific and open enrollment Executive Education programs. Prior to joining Bath, he received his M.Sc. and Ph.D. from INSEAD and was a Postdoctoral Fellow at Northwestern University’s Kellogg School of Management and an Assistant Professor at Rice University’s Jones Graduate School of Business. He received awards for teaching excellence at Kellogg, Rice, and Bath and was selected by Poets & Quants as one of the world’s 40 best business school professors under the age of 40.
