Min Tay, 4th-year student from Nanyang Technology University spent a productive and insightful day with Claus Zieler, Senior Vice President and Head of Commercial Operations at Bayer Pharmaceuticals Division Asia / Pacific

“My idea of a good leader would be someone who is charismatic, someone who can inspire employees with a vision. Caring for his/her team is also a must – a leader who can bring everyone together regardless of their differences. In terms of ability, good leaders have to be a strategic thinker, who can see the bigger picture and help craft it into individual objectives for their team members.”
