My work sits at the intersection of entrepreneurial formation, institutional culture, judgment under uncertainty, and disciplined human development.
I am Executive Director of Yayasan Mens et Manus (Jakarta) and Founder and Director of Aren Energy Investment Pte Ltd (Singapore). I bring over 24 years of executive experience across 52 countries, including thirteen years with Schlumberger in regional and global roles spanning operations, technology deployment, and organizational leadership.
I completed my Doctor of Philosophy in Science in Management at Institut Teknologi Bandung (2023–2026) — Summa Cum Laude, GPA 4.0 of 4.0, Minimum Required Time for Graduation. My doctoral theory — the Dynamic Feedback Theory of Entrepreneurial Formation in Loss-Averse, Short-Horizon Cultures — explains why innovation ecosystems in Indonesia fail not from resource scarcity, but from suppressed feedback loops, cultural risk-aversion, and institutional conformity. Earlier formation includes a Bachelor of Engineering in Nuclear Engineering from Universitas Gadjah Mada (1994), a dual MM/MBA from IPMI Jakarta and Monash University Melbourne (2001), executive education at Harvard Business School (GMP26, Full Alumni, 2019), and fourteen courses at MIT Sloan (ACE, Affiliated Alumni, 2016–2018).
I am a member of the Harvard Business Review Advisory Council and an MIT En-Roads Climate Simulation Ambassador. I am available for board advisory, research collaboration, and speaking engagements. I am Manadonese — from North Sulawesi, Indonesia. I am based across Jakarta, Singapore, and Bandung.
