About Thomas

Thomas holds several leadership positions at McKinsey. He oversees our work in manufacturing and supply chain in Southeast Asia (SEA), our Operations Excellence Program in SEA, and is a core member of our Digital Capability Center in Singapore.

Equally committed to client service, Thomas works with clients in the energy and chemicals sectors, with a focus on oil and gas, petrochemicals, and power. He is passionate about leveraging data and emerging technologies to improve the operation of energy assets. In addition to leading large, complex transformation programs, he serves clients on topics related to digital technology, advanced analytics, and operations—including, manufacturing, supply chain, procurement and capital productivity.

Select examples of his client work include the following:

  • leading an improvement program for a petrochemical company that resulted in more than $300 million EBITDA per year; the program touched operations, supply chain, procurement, maintenance, and capital expenditures
  • supporting a large-scale digital and analytics transformation program at a petrochemical refinery in Southeast Asia
  • helping a client optimize its advanced analytics to improve chemicals production in real time
  • helping to reduce the lead time to supply electricity by more than 50 percent in over 100 locations in Southeast Asia
  • advising on a capital productivity transformation program at a gas facility that increased productivity by 100%
  • leading the transformation of a refinery supply chain; the project involved redesigning key processes, revamping the organizational structure, and building team capabilities

Prior to joining our Jakarta office, Thomas worked in our Chicago, Lyon, and Singapore offices. He served as an officer in the French Army before McKinsey. Outside of work, Thomas loves outdoor adventures and travelling around the world with his wife.
