A paper resolves the Nirenberg-Treves conjecture: that condition ($\Psi$) is sufficient for local solvability for operators of principal type (Ann. of Math. 163 (2006), no. 2, 405-444).
Joint paper with Johannes Sjöstrand and Maciej Zworski about the pseudo-spectra of semi-classical operators (Comm. Pure Appl. Math. 57 (2004), 384-415).
A preprint that studies pseudospectrum for systems of semiclassical operators (Anal. PDE 1 (2008), 323-373).
Another preprint that generalizes the Nirenberg-Treves conjecture to quadratic systems of principal type having constant characteristics (corrected version February 25, 2010). To appear in "Geometric Aspects of Analysis and Mechanics", In Honor of Hans Duistermaat's 65th Birthday.
Latest preprint that proves solvability and subellipticity results of quasi-symmetrizable systems. In "Advances in Phase Space Analysis of Partial Differential Equations", In Honor of Ferruccio Colombini's 60th Birthday.
