Rich Lehoucq was chosen as a SIAM Fellow for his significant contributions to the fields of applied mathematics, computational science, and data science. His work spans nonlocal modeling, numerical linear algebra, continuum mechanics, and the applications of probability to optimization and high dimensional data analysis. Lehoucq’s innovative approach to extending the edges of these fields has led to the development of better tools for engineers, particularly in modeling fractures.
His career at Sandia, shaped by mentorship and a willingness to explore new ideas, has included publishing over 75 papers, co-authoring a book, and contributing to international conferences and journals.
