Dr. Carlos Ortiz, professor of computer science and mathematics, is continuing his research on on reverse mortgages with Drs. Anne Zissu (CUNY ) and Charles Stone (Brooklyn College). Two papers from this collaboration were accepted for publication this year: “When Do Securitized Reverse Mortgages Become Liabilities” (Journal of Structured Finance) and “An Innovative Form of Credit Enhancement for Securitized Reverse Mortgages: Finding paths of cross-over points isolated from changes in interest and inflation rates” (Journal of Risk Finance).
He also continues to work on theoretical computer science with Dr. Argimiro A. Arratia Quesada from the Universitat Politecnica de Catalunya, who presented their research on first order extensions of residue classes at the Workshop on Logic, Language, Information and Computation (WoLLIC) in Germany in August. A paper based on that presentation will be published as “First Order Extensions of Residue Classes and Uniform Circuit Complexity,” with A. Arratia, Logic, Language, Information and Computation, WoLLIC 2013, Lecture Notes in Computer Sciences (L. Libkin et al editors), 8071 (2013), 49-63.
