German Sastre, PhD, is a member of the Structure Commission of the International Zeolite Association. His research focus is on solid state computational chemistry as applied to nanoporous materials, including zeolites and metal-organic frameworks. Frits Daeyaert, PhD, has a background in computational drug design in the pharmaceutical industry. As visiting scientist at Rice University he has developed and applied de novo design methods for the design of organic structure directing agents for zeolite synthesis. He is a co-recipient of the 2019 Donald W. Breck award in Molecular Sieve Science for his contribution to the discovery of enantiomerically enriched STW zeolite.
