Research

Principal research interest is elaborating the interrelationships between protein structure, function, and disease. Both genetic (mutation) and acquired (post-translational) modification of a proteins structure can affect its function and induce disease. Have a specific interest in mutations and disease mechanisms associated with:
  • The haemoglobinopathies and thalassaemias
  • a1 antitrypsin deficiency and liver cirrhosis / emphysema.
  • Antithrombin mutation and deep vein thrombosis / pulmonary embolism.
  • Apolipoprotein mutation and hyperlipidemia.
  • Albumin mutation and familial hyperthyroxemia.
  • Dysfibrinogenaemia and bleeding, thrombosis and renal amyloidosis
  • Hypo-and afibrinogenaemia and its association with bleeding and liver cirrhosis.
