He has extensively contributed in the areas of drug targeting in parasitic diseases and membrane phospholipids transbilayer dynamics, and is currently working on elucidation of actin cytoskeletal network in Leishmania.
For example, perfringolysin O will preferentially bind to cholesterol-rich membranes composed mainly of phospholipids containing 18-carbon acyl chains.
He started a professional career as a lawyer before marrying one of the daughters of Theodore Gobley, a French chemist known for research on the brain, who also discovered lecithin and phospholipids.
