This week on Catalyst, Tammy is joined by Sezin Palmer, AI Solutions Leader at NTT DATA in North America. Sezin traces her impressive and unconventional journey from CIA analyst and Navy submarine warfare programs to building the National Health Mission area at Johns Hopkins' Applied Physics Lab from scratch, then leading health AI and data at EY. Tammy and Sezin dig into the democratization of AI and what it means that capabilities once locked behind years of data science training are now accessible to nearly anyone. They also discuss the thorny challenge of how organizations decide what not to build and why the hardest leadership problem right now isn't launching AI, it's knowing when to stop. Sezin also shares her vision for what has her most excited: the convergence of software, robotics, and biology.

This week on Catalyst, Tammy is joined by Abhijit Sunil, Senior Analyst at Forrester Research, where he leads flagship research programs on IT sustainability, sustainability management, and climate risk. Abhijit traces his remarkable journey from designing robotics labs at IIT Bombay to consulting at Ericsson and McKinsey, before landing at Forrester where a flood of client questions about data center efficiency set him on the path to sustainability research. He shares how volunteering as a teacher in Mumbai's slums profoundly shaped his worldview—giving him a lens for seeing optimization and sustainability as deeply human issues, not just technical ones. Tammy and Abhijit also dig into the double-edged nature of AI, from its staggering energy demands to its extraordinary potential to democratize access, and why the answer to almost every big question in sustainability lives somewhere in the Goldilocks zone between extremes.
