Parker Hood is a lecturer in Commercial Law in the School of Law.

His main interests are:
(i) banking law - particularly, the banker/customer relationship, and lender liability;
(ii) company law - particularly, directors' duties and minority shareholders;
(iii) the law of obligations - particularly, contractual damages and aspects of the law of unjustified enrichment; and
(iv) general commercial law - particularly, sale and hire of goods.

At present, Parker Hood is writing a book on Principles of Lender Liability (OUP). This concerns the liability of banks and other financial institutions for wrongful conduct towards customers and third parties, e.g., disclosing confidential information, giving negligent advice, selling secured assets at an undervalue, and breaching a contract by refusing to provide agreed finance. The basis of the book is English law and Scots law, although reference is made to other jurisdictions - especially Commonwealth countries.

Parker Hood teaches at: (i) Undergraduate level (company law), (ii) Honours level (banking law) and (iii) Postgraduate level (company law and banking law). He has supervised dissertations at LLM and Honours level, as well as at  Ph D level.
