Linda Petzold
Linda Ruth Petzold (* 1954 in Chicago ) is an American computer scientist and systems biologist.
Petzold studied mathematics and computer science at the University of Illinois at Urbana-Champaign with a bachelor's degree in 1974 and a doctorate from Charles William Gear in 1978 ( An Efficient Numerical Method for Highly Oscillatory Ordinary Differential Equations ). She then worked at Sandia National Laboratories , Lawrence Livermore National Laboratory and Professor at the University of Minnesota . She is the Mehrabian Distinguished Professor in the Department of Mechanical Engineering and Computer Science at the University of California, Santa Barbara (UCSB), where she has been a faculty member since 1997.
Petzold is known for the development of software for solving differential-algebraic equations (DAE), coupled differential equation systems that also satisfy non-linear algebraic equations. Their software DASSL and its successor DASPK found widespread use.
She dealt with mathematical modeling in systems biology (biochemical systems on multiple scales) and the development of algorithms for the associated discrete stochastic systems. Their software for discrete stochastic systems StochKit2 and StochSS (a cloud-based stochastic simulation service) was also widely used. The systems she has examined include gene regulation networks for circadian rhythms of neurons (and application to jet lag), cell polarization, a fungal disease of frogs (chytridiomycosis), post-traumatic stress syndrome, coagulopathy and type 2 diabetes. She also dealt with applications on social networks.
In 2018 she received the Sidney Fernbach Award for her pioneering contributions to numerical methods and software for differential algebraic systems and for discrete stochastic simulation (laudation). In 1991 she received the first JH Wilkinson Prize for Numerical Software for DASSL and the Dahlquist Prize in 1999. In 2013 she received the SIAM / ACM Prize for Computational Science and Engineering and in 2016 the SIAM Prize for Distinguished Service. She is a Fellow of the ACM , the American Society of Mechanical Engineers , the SIAM and the American Association for the Advancement of Science and a member of the National Academy of Engineering (2004). Petzold is an honorary doctorate from Uppsala University. In 2011 she became a Faculty Research Lecturer at UCSB, which is considered the university's highest honor.
