I am an assistant professor in computer science at UofSC and a visiting researcher at Google. My research involves developing theories in Causal AI and Statistical ML and apply them for solving problems in computer systems, autonomous robots, and software engineering. I am, in particular, interested in Representation Learning, Causal Transfer Learning, Reinforcement Learning, Trustworthy AI, and ML for Systems.

Prior to joining the faculty at the University of South Carolina, I was a post-doc in the School of Computer Science at Carnegie Mellon University working with Christian Kaestner, and, before that, I was a post-doc in the Department of Computing at Imperial College London. I received my Ph.D. from the School of Computing at Dublin City University and my advisor was Claus Pahl.

Current Projects

NASA RASPBERRY-SI

NASA RASPBERRY-SI (2020–) Jianhai Su Pooyan Jamshidi

In this collaborative project (USC, CMU, York, UArk, NASA JPL/Ames/GRC), we develop technologies that enable learning-based autonomous planning and adaptation of space landers.

Causal AI: Structure Learning and Transfer Learning

Causal AI: Structure Learning and Transfer Learning (2018–) Mohammad Ali Javidian Pooyan Jamshidi

In this project, we are addressing the following important questions from theoretical and empirical perspectives: (i) How to learn reliable causal structures from data and how to use the learned causal structures for identifying causal invariances across environments? (ii) How to use the causal structure learning and counterfactual reasoning based on causal invariances for systems problems? In particular, we are extremely interested to apply these theoretical advancements for an explainable and guided performance debugging of highly-configurable systems.

ATHENA

ATHENA (2019–) Ying Meng Jianhai Su Pooyan Jamshidi

Despite achieving state-of-the-art performance across many domains, machine learning systems are highly vulnerable to subtle adversarial perturbations. In this project, we propose Athena, an extensible framework for building effective defenses to adversarial attacks against machine learning systems.

FlexiBO

FlexiBO (2018–) Md Shahriar Iqbal Jianhai Su Pooyan Jamshidi

One of the key challenges in designing machine learning systems is to determine the right balance amongst several objectives, which also oftentimes are incommensurable and conflicting. For example, when designing deep neural networks (DNNs), one often has to trade-off between multiple objectives, such as accuracy, energy consumption, and inference time. We developed FlexiBO, a flexible Bayesian optimization method, to address this issue.

BRASS MARS

BRASS MARS (2016–) Jianhai Su Pooyan Jamshidi

How do you build a software system that can function for a century without being touched by a human engineer? This is the herculean task being undertaken by the DARPA Building Resource Adaptive Software System’s (BRASS) program. We, at UofSC with several collborators at CMU, have been developing learning mechanisms to be integrated with quantitative planning to adapt/reconfigure robots to overcome environmental changes at runtime.
