• Proven track record in collaboration with industry (See “Research Interests”)
Professor Walker has repeatedly demonstrated successful collaboration with international industry partners and has industrially funded projects that have delivered improvements in:
• Product quality (BP Chemicals, via continuous distillation)
• New processes (AstraZeneca, via microwave drying PAT)
• Energy/environmental efficiency (ExxonMobil and Bombardier Aerospace, via new adsorption processes)
• New product development & new products (P&G, via a new encapsulation system; SABIC, via controlled release product)
• Powder engineering (Roche and Pfizer, via powder flow prediction)
• Pharmaceutical engineering (Pfizer, Eli-Lilly, GSK, Genzyme, Allergan, Sun pharma, Ethicon, J&J, Janssen, Regeneron, Nestle, Stryker)
