Short Bio

Dr. Rigoutsos is the Founding Director of the Computational Medicine Center at Thomas Jefferson University. He joined Jefferson in early 2010 as a Professor with an appointment in the Department of Pathology, Anatomy & Cell Biology. He also has joint appointments in the Department of Cancer Biology, and the Department of Biochemistry & Molecular Biology, and is a member of the University's Sidney Kimmel Cancer Center.

Prior to joining Jefferson, Dr. Rigoutsos worked at IBM's Thomas J. Watson Research Center for nearly 18 years. There, he co-founded the Computational Biology Center in 1992. He also founded the Bioinformatics and Pattern Discovery group in 1998 and managed it until his departure from the company. In parallel to his IBM tenure, Dr. Rigoutsos was for a decade (2000-2010) a Visiting Lecturer at MIT's Dept. of Chemical Engineering where he taught graduate-level classes and summer professional courses in Bioinformatics, and co-supervised PhD students. Dr. Rigoutsos’ involvement in the field of Computational Biology spans more than 25 years. Since 1996, his efforts have revolved around the theoretical and practical aspects of pattern discovery and the design of pattern-based solutions to a variety of problems from genomics, genetics, molecular biology and medicine.

Beginning in 2002, Dr. Rigoutsos’ work has been focused nearly exclusively on the study of post-transcriptional regulation by non-coding RNAs, including microRNAs, pyknons, piRNAs, and tRNA-derived fragments. Of particular interest are the questions surrounding the biogenesis of such non-coding RNAs, the mechanisms of action and the automated discovery of their targets, the discovery of novel organism-specific regulatory sequences, and the elucidation of the roles of non-coding RNAs in the onset and progression of disease. Two notable algorithmic contributions by Dr. Rigoutsos are: 1) the Teiresias algorithm (see paper and code) for the deterministic and exhaustive discovery of patterns in one-dimensional data streams. Named after the Greek blind seer Teiresias, the algorithm can guarantee the deterministic and exhaustive discovery of all patterns in a given dataset that satisfy a user's criteria while obviating the need to enumerate the underlying search space. Because of its data agnostic nature the algorithm has found numerous applications in diverse fields including biology, medicine, computer security, and elsewhere.

2) the Berger-Rigoutsos algorithm (see paper) for dynamic gridding when using the adaptive mesh refinement method. When solving partial differential equations in 2 and 3 dimensions, an interesting problem arises: as one works on improving the solution at points needing refinement, it is important to maximize the use of the available computing power while minimizing unnecessary computation. This problem reduces to the problem of embedding the grid points needing refinement into rectangles that are neither too small nor too big. The Berger-Rigoutsos algorithm represents a natural solution to the problem and borrows its key idea from computer vision. Here are two beautiful videos of the algorithm tracking an evolving 2D bubble (watch video) or an evolving 3D bubble (watch video). The Berger-Rigoutsos algorithm is now a standard technique for handling clustering in adaptive mesh refinement.

A graduate of the Physics Dept. of the National and Kapodistrian University of Athens, Greece, Dr. Rigoutsos received a Master’s in Computer Science from the University of Rochester, and a Master’s and Doctoral degrees in Computer Science from the Courant Institute of Mathematical Sciences of New York University.
