HOUSTON, March 24, 2022 – Lummus Technology announced that Ujjal Mukherjee will become the company’s Chief Technology Officer (CTO) as of April 1. He succeeds Jo Portela, who upon retirement will transition to an advisory role to Lummus’ board of directors and executive team.
As CTO, Mr. Mukherjee will be responsible for driving cross-company initiatives to enhance and grow Lummus’ broad portfolio and champion the company’s technology solutions to strategic customers. He will also lead the development of advanced technology solutions that place Lummus at the forefront of our industry, the energy transition and digitalization.
“I am very proud to announce Ujjal as Lummus’ next CTO. Ujjal has an outstanding track record of innovation, performance and execution, which I had the pleasure of witnessing first hand for many years,” said Leon de Bruyn, President and Chief Executive Officer of Lummus Technology. “The direction and strategic goals of our company are inextricably tied to the CTO role, and I am confident in Ujjal to take Lummus’ technology leadership to a new level.
