Dr. Ioannis Costas holds a doctoral degree in Chemistry and specialises in Catalysis and Organic Synthesis. His research, a palladium complex for the Suzuki reaction, is commercially available. He explains how Catalysis is a widely used process in chemistry & engineering with over 80% of all industrial processes involving it. Used in energy, food, industrial products, pharmaceuticals and many more fields, life as we know it, would be impossible without catalysis. Dr. Costas talks about his fields of practice including green chemistry and transition metal homogenous catalysis. Unfortunately, time was limited and the interviewer could not go deeper into the science but had to wrap it up with a question on how he would motivate young students to follow Chemistry.
