- Hava Siegelmann
**Hava Siegelmann**is aComputer Scientist at theUniversity of Massachusetts who is Director of their Biologically Inspired Neural and Dynamical Systems Lab [*[*] . In the early*http://binds.cs.umass.edu/index.html BINDS Lab*]1990 s she proposed a new computational model, the Artificial Recurrent Neural Network (ARNN), and proved that it could performhypercomputation [*[*] . She is considered the originator of the term Super-Turing, a subfield which started after her contribution. Hava has also been oneof the originators of the well-known Support Vector Clustering together with Vladimir Vapnik and colleagues. Lately she has published an original work in the field of System-Biology explicating the inter-clock dynamics causing Jet-lag.*http://www.cs.math.ist.utl.pt/ftp/pub/CostaJF/01-RCS-iwann.pdf Verifying Properties of Neural Networks*]**Biography**She earned her BA at

Technion , her MSc atHebrew University and her PhD atRutgers University , all in Computer Science [*[*] .*http://binds.cs.umass.edu/havaBio.html Biography at UMass*]Her initial publications on the computational power of

Neural Networks culminated in a sole-author paper in Science [*H.T.
