Singularities express irregularities of form in many branches of mathematics in a way similar to what it means in an everyday language and are a basic object of study in most of the mathematics and its applications. The important features of form are often concentrated at singularities. The objective of my research is to find links between the information encoded in the geometry of and the analysis on singular objects.This led me to a discovery of fundamental links between algebraic, analytic and geometric aspects of singularities, particularly in solutions of longstanding problems posed by Whitney, Thom and Hironaka - the originators of the singularity theories in geometry and algebra. This also led me to an extension of classical Sobolev-Nirenberg and Bernstein-Markov inequalities to a singular setting, and to a discovery of `tame' subanalytic sets on which one can do classical local analysis.

奇点在数学的许多分支中以一种类似于它在日常语言中的含义的方式表达形式的不规则性，并且是大多数数学及其应用中的基本研究对象。形式的重要特征往往集中在奇点上。我的研究目标是找到编码在奇异物体的几何和分析的信息之间的联系。这使我发现了代数，分析和几何方面的奇点之间的基本联系，特别是在解决惠特尼，托姆和Hironaka提出的长期问题-几何和代数奇点理论的创始人。这也使我扩展到经典的Sobolev，尼伦贝格和伯恩斯坦，马尔可夫不等式的奇异设置，并发现了'驯服' subanalytic集上，人们可以做经典的本地分析。
