I specialize in trusts; more generally speaking, I specialize in the comparative study of trusts law, fiduciary law, estates (succession & wills) law, "elder law", pensions, insurance, and relevant issues of tax and family law. 

I make intensive use of empirical research methods, having published comparative research on the reform and transformation of trust law and trust practice in dozens of countries worldwide. Other work addressed the so-called "rule in Re Hastings-Bass" and trust parties' uniquely easy access to rescission; different jurisdictions' treatment of property transfers to caregivers; the proper ambit of trust jurisdiction clauses; the convergence of trust law and corporate law; the uses made of private trusts in Israel and, earlier, Palestine; Eighteenth Century English law; Adam Smith and the Scottish Enlightenment; and the current rise, in Israel, of non-state halachic adjudication in private law matters.

I have taught the basic trust law course under the laws of England, of Ontario, and of Israel, as well as a wide-ranging class in comparative and offshore trust law and practice. I also regularly teach corporate law.

I have been a member of STEP - the Society of Trusts and Estates Practitioners - since 2008, having received that organization's Diploma in International Trust Management in 2010. 
In 2013, I was a Visiting Professor at Georgetown Law Center, as well as at the Centre for Transnational Legal Studies in London, UK.
In 2015, I was a Martin Flynn Global Law Professor at the University of Connecticut School of Law.
In 2017-2018 I was a Visiting Professor at Western Ontario University, Faculty of Law.

In 2020 I was a Visiting Professor at the University of Virginia Law School. 

I won the Cegla prize in 2010 and the Zeltner Prize for Young Researchers in 2017.
