About me

I am an Assistant Professor in the School of Computing. My research revolves around robotics, interactive virtual worlds, and data science. Before coming to Clemson, I was a postdoctoral researcher in the Department of Computer Science & Engineering at the University of Minnesota. I received my PhD in Computer Science from Utrecht University, where I developed motion planning algorithms for crowd simulation purposes, working under the supervision of Prof. Mark Overmars and Prof. Frank van der Stappen.

Research

My main research interests include motion planning, crowd simulation, and data analysis. I am particularly interested in the development of motion planning algorithms for virtual humans, autonomous robots and crowds of virtual characters. See below for some recent work.

Teaching

• Spring 2020: CPSC 8810 - Motion Planning . I am thrilled to be teaching motion planning this semester across three campuses (Clemson, ICAR, CURI-Charleston). This year will have a number of assignments on local collision avoidance, sampling-based planning (PRM, RRT), and RL-based control. See the course website for details.
• Fall 2019: Intro to AI, and Computer Graphics Images.
• Spring 2019: I'm teaching Motion Planning (CPSC 8810), and Intro to AI (CPSC 4820/6820). CPSC4820/6820 is a new course with the goal of providing an introduction to the fundamental concepts of Artificial Intelligence and Machine Learning. Topics will include: agents, uninformed and informed search techniques, reinforcement learning, perceptrons, and supervised learning. The course is suitable for undergraduate and young graduate students to gain a solid technical background and as a preparation for more advanced work in AI. See the course website for details.
• Fall 2018: CPSC 4040/6040. I am teaching Computer Graphics Images this fall. See the course website for details.
• Spring 2018: CPSC 8810. I am teaching motion planning this semester. We will cover different techniques with applications to robotics, and interactive computer graphics. The class will involve programming assignments, as well as a final project, either simulation-based or on a Turtlebot. See the course website for details.
• Fall 2017: CPSC 4040/6040. The class will focus on the theory and practice behind the generation and manipulation of digital images. Topics include image representation and storage, color systems, affine and general warps, compositing, morphing, and non-photorealistic transformations. See the course website for details.
• Spring 2017: CPSC 8050. The class will focus on motion planning techniques for robotics and computer graphics with topics that include A*, dynamic programming, local collision avoidance, kalman filtering, numerical optimization, etc. See the course website and here for more details.
• Fall 2016: CPSC 6040 - Computer Graphics Images.
