My research focuses on understanding the processes and time-scales over which brittle faults grow, interact and evolve. This includes studying fault structure and patterns of displacement accumulation on faults, fault scaling relationships, and the temporal evolution recorded in basin stratigraphy and in landscapes.  Geographically, much of my work on fault evolution and tectonic landscape development has been within the Eastern California shear zone and in the northern Basin & Range. I also have projects in south Louisiana looking at recently active faults, how salt flow affects these faults, and the contribution of these processes to subsidence and coastal wetland loss.

Nicholas Mattei is an Assistant Professor of Computer Science at Tulane University. His research focuses on the theory and practice of artificial intelligence; largely motivated by problems that require a blend of techniques to develop systems and algorithms that support decision making for autonomous agents and/or humans. Most of his projects and leverage theory, data, and experiment to create novel algorithms, mechanisms, and systems that enable and support individual and group decision making.

Before joining Tulane he was a Research Staff Member in the IBM TJ Watson Research Laboratory in the IBM Research AI – Reasoning Lab where he worked on a number of topics including Complex Question Answering / Natural Language Inference, Decision Making, and issues in AI, Ethics, and Society. Before that he was a senior researcher working with Prof. Toby Walsh in the AI & Algorithmic Decision Theory Group at Data61 (formerly known as the Optimisation Group at NICTA). At NICTA he was the founder and maintainer of PrefLib: A Library for Preferences; the associated PrefLib:Tools available on Github; and has been the founder/co-chair for the Exploring Beyond the Worst Case in Computational Social Choice (2014, 2015, 2016 2017) held at AAMAS. He was/is also an adjunct lecturer in the School of Computer Science and Engineering (CSE) and member of the Algorithms Group at the University of New South Wales. He previously worked as a programmer and embedded electronics designer for nano-satellites at NASA Ames Research Center. He received his Ph.D from the University of Kentucky under the supervision of Prof. Judy Goldsmith in 2012.

Nicholas has served on the SPC or PC of AAAI, AAMAS, AIES, IJCAI, COMSOC, ECAI, CP and other major AI conferences.  He has reviewed for AIJ, AGNT, JAIR, IEEE Intelligent Systems, ACM:TEAC and other journals.  He serves as the AI, Ethics, and Society Officer for ACM:SIGAI and as the Public Relations coordinator for JAIR.

Parisa Kordjamshidi currently is an assistant professor of computer science at Tulane University and holds a joint appointment as a research scientist at IHMC. Her main research interests are artificial intelligence, machine learning, natural language processing, Information extraction and Declarative learning based programming. She has worked on the extraction of formal semantics and structured representations from natural language, with a specific focus on spatial semantics representation. Her current research is dedicated to declarative learning based programming (DeLBP). The goal of this programming paradigm is to facilitate programming for building systems that require a number of learning and reasoning components that interact with each other and receive data from heterogeneous resources. Such a language would help machine learning researchers as well as experts in various domains who are not experts in machine learning, to design complex intelligent systems and evaluate them. She tries to develop such a language and apply it on various application domains.

Dr. Kordjamshidi received her PhD from KU Leuven University, in 2013 and was a postdoc in University of Illinois at Urbana-Champaign before joining Tulane and IHMC. She is a member of Editorial board of Journal of Artificial Intelligence Research (JAIR). She has organized a number of international workshops and served as program committee of conferences such as IJCAI, AAAI, ACL-IJCNLP, COLING and ECAI. The results of her research have been published in several international peer-reviewed conferences and journals including ACM-TSLP, JWS, BMC-Bioinformatics, IJCAI.

Research Interests

Artificial Intelligence, Machine Learning, Natural language Processing, Declarative Learning based programming, Knowledge representation, information extraction, Extraction of spatial semantics from language, big data, and text mining.

My research interests are in algorithms, machine learning and computational biology. Specifically, my work is focused on the design and analysis of algorithms with guarantees on running time and solution quality that are motivated by, and are necessary for, problems in computational biology. Applications of my work include protein structure prediction and determination, protein-protein interactions, compound screening, as well as problems in high-throughput sequencing and proteomics.
